COVID-19 FAQS

Frequently Asked Questions Provided by CDC

Coronavirus Disease 2019 Basics

A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

A diagnosis with coronavirus 229E, NL63, OC43, or HKU1 is not the same as a COVID-19 diagnosis. Patients with COVID-19 will be evaluated and cared for differently than patients with common coronavirus diagnosis.

On February 11, 2020 the World Health Organization announced an official name for the disease that is causing the 2019 novel coronavirus outbreak, first identified in Wuhan China. The new name of this disease is coronavirus disease 2019, abbreviated as COVID-19. In COVID-19, ‘CO’ stands for ‘corona,’ ‘VI’ for ‘virus,’ and ‘D’ for disease. Formerly, this disease was referred to as “2019 novel coronavirus” or “2019-nCoV”.

There are many types of human coronaviruses including some that commonly cause mild upper-respiratory tract illnesses. COVID-19 is a new disease, caused be a novel (or new) coronavirus that has not previously been seen in humans. The name of this disease was selected following the World Health Organization (WHO) best practiceexternal iconexternal icon for naming of new human infectious diseases.

People in the U.S. may be worried or anxious about friends and relatives who are living in or visiting areas where COVID-19 is spreading. Some people are worried about getting the disease from these people. Fear and anxiety can lead to social stigma, for example, toward people who live in certain parts of the world, people who have traveled internationally, people who were in quarantine, or healthcare professionals.

Stigma is discrimination against an identifiable group of people, a place, or a nation. Stigma is associated with a lack of knowledge about how COVID-19 spreads, a need to blame someone, fears about disease and death, and gossip that spreads rumors and myths.

Stigma hurts everyone by creating more fear or anger toward ordinary people instead of focusing on the disease that is causing the problem.

People can fight stigma by providing social support in situations where you notice this is occurring. Stigma affects the emotional or mental health of stigmatized groups and the communities they live in. Stopping stigma is important to making communities and community members resilient. See resources on mental health and coping during COVID-19. Everyone can help stop stigma related to COVID-19 by knowing the facts and sharing them with others in your community.

CDC’s overall case numbers are validated through a confirmation process with jurisdictions. The process used for finding and confirming cases displayed by different places may differ.

CDC’s COVID-19 case numbers include many publicly reported numbers, including information from state, local, territorial, international and external partners.

Delays in reporting can cause the number of COVID-19 cases reported on previous days to increase. (Sometimes this effect is described as “backfill.”) State, local, and territorial health departments report the number of cases that have been confirmed and share these data with CDC. Since it takes time to conduct laboratory testing, cases from a previous day may be added to the daily counts a few days late.

 

How COVID-19 Spreads

COVID-19 is caused by a coronavirus called SARS-CoV-2. Coronaviruses are a large family of viruses that are common in people and may different species of animals, including camels, cattle, cats, and bats.  Rarely, animal coronaviruses can infect people and then spread between people. This occurred with MERS-CoV and SARS-CoV, and now with the virus that causes COVID-19. The SARS-CoV-2 virus is a betacoronavirus, like MERS-CoV and SARS-CoV. All three of these viruses have their origins in bats. The sequences from U.S. patients are similar to the one that China initially posted, suggesting a likely single, recent emergence of this virus from an animal reservoir. However, the exact source of this virus is unknown.

More information about the source and spread of COVID-19 is available on the Situation Summary: Source and Spread of the Virus.

The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).

COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in many affected geographic areas. Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.

Learn what is known about the spread of newly emerged coronaviruses.

The number of cases of COVID-19 being reported in the United States is rising due to increased laboratory testing and reporting across the country. The growing number of cases in part reflects the rapid spread of COVID-19 as many U.S. states and territories experience community spread. More detailed and accurate data will allow us to better understand and track the size and scope of the outbreak and strengthen prevention and response efforts.

The virus that causes COVID-19 is spreading from person-to-person. People are thought to be most contagious when they are symptomatic (the sickest). That is why CDC recommends that these patients be isolated either in the hospital or at home (depending on how sick they are) until they are better and no longer pose a risk of infecting others. More recently the virus has also been detected in asymptomatic persons.

How long someone is actively sick can vary so the decision on when to release someone from isolation is made using a test-based or non-test-based strategy (i.e. time since illness started and time since recovery) in consultation with state and local public health officials. The decision involves considering the specifics of each situation, including disease severity, illness signs and symptoms, and the results of laboratory testing for that patient.

Learn more about CDC’s guidance on when to release someone from isolation and discharge hospitalized patients with COVID-19. For information on when someone who has been sick with COVID-19 is able to stop home isolation see Interim Guidance for Discontinuation of In-Home Isolation for Patients with COVID-19.

Someone who has been released from isolation is not considered to pose a risk of infection to others.

Quarantine means separating a person or group of people who have been exposed to a contagious disease but have not developed illness (symptoms) from others who have not been exposed, in order to prevent the possible spread of that disease. Quarantine is usually established for the incubation period of the communicable disease, which is the span of time during which people have developed illness after exposure. For COVID-19, the period of quarantine is 14 days from the last date of exposure because the incubation period for this virus is 2 to 14 days. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because they have not developed illness during the incubation period.

Coronaviruses are generally thought to be spread from person to person through respiratory droplets. Currently, there is no evidence to support transmission of COVID-19 associated with food. Before preparing or eating food it is important to always wash your hands with soap and water for at least 20 seconds for general food safety. Throughout the day use a tissue to cover your coughing or sneezing, and wash your hands after blowing your nose, coughing or sneezing, or going to the bathroom.

It may be possible that a person can get COVID-19 by touching a surface or object, like a packaging container, that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

In general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from food products or packaging.

Learn what is known about the spread of COVID-19.

Based on information about this novel coronavirus thus far, it seems unlikely that COVID-19 can be transmitted through food – additional investigation is needed.

It is not yet known whether weather and temperature affect the spread of COVID-19. Some other viruses, like those that cause the common cold and flu, spread more during cold weather months but that does not mean it is impossible to become sick with these viruses during other months.  There is much more to learn about the transmissibility, severity, and other features associated with COVID-19 and investigations are ongoing.

Community spread means people have been infected with the virus in an area, including some who are not sure how or where they became infected.

Generally coronaviruses survive for shorter periods at higher temperatures and higher humidity than in cooler or dryer environments. However, we don’t have direct data for this virus, nor do we have direct data for a temperature-based cutoff for inactivation at this point. The necessary temperature would also be based on the materials of the surface, the environment, etc. Regardless of temperature please follow CDC’s guidance for cleaning and disinfection.

At this time, CDC has no data to suggest that this new coronavirus or other similar coronaviruses are spread by mosquitoes or ticks. The main way that COVID-19 spreads is from person to person. See How Coronavirus Spreads for more information.

 

How to Protect Yourself

This is a rapidly evolving situation and the risk assessment may change daily. The latest updates are available on CDC’s Coronavirus Disease 2019 (COVID-19) website.

COVID-19 case counts for the United States are updated regularly online. See the current U.S. case count of COVID-19.

Visit the COVID-19 Prevention and Treatment page to learn about how to protect yourself from respiratory illnesses, like COVID-19.

There is information for people who have had close contact with a person confirmed to have, or being evaluated for, COVID-19 available online.

In light of new data about how COVID-19 spreads, along with evidence of widespread COVID-19 illness in communities across the country, CDC recommends that people wear a cloth face covering to cover their nose and mouth in the community setting. This is an additional public health measure people should take to reduce the spread of COVID-19 in addition to (not instead of) social distancing, frequent hand cleaning and other everyday preventive actions. A cloth face covering is not intended to protect the wearer, but may prevent the spread of virus from the wearer to others. This would be especially important in the event that someone is infected but does not have symptoms. A cloth face covering should be worn whenever people must go into public settings (grocery stores, for example). Medical masks and N-95 respirators are reserved for healthcare workers and other first responders, as recommended by current CDC guidance.

There is still a lot that is unknown about COVID-19 and how it spreads. Coronaviruses are thought to be spread most often by respiratory droplets. Although the virus can survive for a short period on some surfaces, it is unlikely to be spread from domestic or international mail, products or packaging. However, it may be possible that people can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.

Learn more about safe handling of deliveries and mail.

In healthcare settings across the United States, donated blood is a lifesaving, essential part of caring for patients. The need for donated blood is constant, and blood centers are open and in urgent need of donations. CDC encourages people who are well to continue to donate blood if they are able, even if they are practicing social distancing because of COVID-19. CDC is supporting blood centers by providing recommendations that will keep donors and staff safe. Examples of these recommendations include spacing donor chairs 6 feet apart, thoroughly adhering to environmental cleaning practices, and encouraging donors to make donation appointments ahead of time.

  • Currently there is no evidence to suggest contact lens wearers are more at risk for acquiring COVID-19 than eyeglass wearers.
  • Contact lens wearers should continue to practice safe contact lens wear and care hygiene habits to help prevent against transmission of any contact lens-related infections, such as always washing hands with soap and water before handling lenses.
  • People who are healthy can continue to wear and care for their contact lenses as prescribed by their eye care professional.

Find more information about how coronavirus spreads and how to protect yourself.

Visit CDC’s contact lens website for more information on healthy contact lens wear and care.

  • Hydrogen peroxide-based systems for cleaning, disinfecting, and storing contact lenses should be effective against the virus that causes COVID-19.
    • For other disinfection methods, such as multipurpose solution and ultrasonic cleaners, there is currently not enough scientific evidence to determine efficacy against the virus.
  • Always use solution to disinfect your contact lenses and case to kill germs that may be present.
  • Handle your lenses over a surface that has been cleaned and disinfected.

COVID-19 and Children

Based on available evidence, children do not appear to be at higher risk for COVID-19 than adults. While some children and infants have been sick with COVID-19, adults make up most of the known cases to date. You can learn more about who is at higher risk for severe illness from COVID-19 at People who are at higher risk for severe illness.

You can encourage your child to help stop the spread of COVID-19 by teaching them to do the same things everyone should do to stay healthy.

  • Avoid close contact with people who are sick.
  • Stay home when you are sick, except to get medical care.
  • Cover your coughs and sneezes with a tissue and throw the tissue in the trash.
  • Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Clean and disinfect frequently touched surfaces and objects (e.g., tables, countertops, light switches, doorknobs, and cabinet handles).
  • Launder items, including washable plush toys, as appropriate and in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry from an ill person can be washed with other people’s items.

You can find additional information on preventing COVID-19 at Prevention for 2019 Novel Coronavirus and at Preventing COVID-19 Spread in Communities. Additional information on how COVID-19 is spread is available at How COVID-19 Spreads.

More information on Children and Coronavirus Disease 2019 (COVID-19) is available online.

No. The symptoms of COVID-19 are similar in children and adults. However, children with confirmed COVID-19 have generally presented with mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher risk for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.

CDC recommends that everyone 2 years and older wear a cloth face covering that covers their nose and mouth when they are out in the community. Cloth face coverings should NOT be put on babies or children younger than 2 because of the danger of suffocation. Children younger than 2 years of age are listed as an exception as well as anyone who has trouble breathing or is unconscious, incapacitated, or otherwise unable to remove the face covering without assistance.

Wearing cloth face coverings is a public health measure people should take to reduce the spread of COVID-19 in addition to (not instead of) social distancing, frequent hand cleaning ,and other everyday preventive actions. A cloth face covering is not intended to protect the wearer but may prevent the spread of virus from the wearer to others. This would be especially important if someone is infected but does not have symptoms. Medical face masks and N95 respirators are still reserved for healthcare personnel and other first responders, as recommended by current CDC guidance.

Outbreaks can be stressful for adults and children. Talk with your children about the outbreak, try to stay calm, and reassure them that they are safe. If appropriate, explain to them that most illness from COVID-19 seems to be mild. Children respond differently to stressful situations than adults. CDC offers resources to help talk with children about COVID-19.

This is a new virus and we are still learning about it, but so far, there does not seem to be a lot of illness in children. Most illness, including serious illness, is happening in adults of working age and older adults. However, children do get the virus and become ill. Many schools across the country have announced dismissals for temporary periods. Keep track of school dismissals in your community. Read or watch local media sources that report school dismissals. If schools are dismissed temporarily, use alternative childcare arrangements, if needed.

If your child/children become sick with COVID-19, notify their childcare facility or school. Talk with teachers about classroom assignments and activities they can do from home to keep up with their schoolwork.

Discourage children and teens from gathering in other public places while school is dismissed to help slow the spread of COVID-19 in the community.

 

School Dismissals and Children

  • The key to slowing the spread of COVID-19 is to practice social distancing. While school is out, children should not have in-person playdates with children from other households. If children are playing outside their own homes, it is essential that they remain 6 feet from anyone who is not in their own household.
  • To help children maintain social connections while social distancing, help your children have supervised phone calls or video chats with their friends.
  • Make sure children practice everyday preventive behaviors, such as washing their hands often with soap and water. Remember, if children meet outside of school in groups, it can put everyone at risk.
    • Revise spring break plans if they included non-essential travel.
  • Information about COVID-19 in children is somewhat limited, but current data suggest children with COVID-19 may have only mild symptoms. However, they can still pass this virus onto others who may be at higher risk, including older adults and people who have serious underlying medical conditions.
  • Stay in touch with your child’s school.
    • Many schools are offering lessons online (virtual learning). Review assignments from the school, and help your child establish a reasonable pace for completing the work. You may need to assist your child with turning on devices, reading instructions, and typing answers.
    • Communicate challenges to your school. If you face technology or connectivity issues, or if your child is having a hard time completing assignments, let the school know.
  • Create a schedule and routine for learning at home, but remain flexible.
    • Have consistent bedtimes, and get up at the same time, Monday through Friday.
    • Structure the day for learning, free time, healthy meals and snacks, and physical activity.
    • Allow flexibility in the schedule—it’s okay to adapt based on your day.
  • Consider the needs and adjustment required for your child’s age group.
    • The transition to being at home will be different for preschoolers, K-5, middle school students, and high school students. Talk to your child about expectations and how they are adjusting to being at home versus at school.
    • Consider ways your child can stay connected with their friends without spending time in person.
  • Look for ways to make learning fun.
    • Have hands-on activities, like puzzles, painting, drawing, and making things.
    • Independent play can also be used in place of structured learning. Encourage children to build a fort from sheets or practice counting by stacking blocks.
    • Practice handwriting and grammar by writing letters to family members. This is a great way to connect and limit face-to-face contact.
    • Start a journal with your child to document this time and discuss the shared experience.
    • Use audiobooks or see if your local library is hosting virtual or live-streamed reading events.

Check with your school on plans to continue meal services during the school dismissal. Many schools are keeping school facilities open to allow families to pick up meals or are providing grab-and-go meals at a central location.

  • Watch your child for any signs of illness.
    • If you see any sign of illness consistent with symptoms of COVID-19, particularly fever, cough, or shortness of breath, call your healthcare provider and keep your child at home and away from others as much as possible. Follow CDC’s guidance on “What to do if you are sick.”
  • Watch for signs of stress in your child.
  • Teach and reinforce everyday preventive actions.
    • Parents and caretakers play an important role in teaching children to wash their hands. Explain that hand washing can keep them healthy and stop the virus from spreading to others.
    • Be a good role model—if you wash your hands often, they’re more likely to do the same.
    • Make handwashing a family activity.
  • Help your child stay active.
    • Encourage your child to play outdoors—it’s great for physical and mental health. Take a walk with your child or go on a bike ride.
    • Use indoor activity breaks (stretch breaks, dance breaks) throughout the day to help your child stay healthy and focused.
  • Help your child stay socially connected.

Older adults and people who have serious underlying medical conditions are at highest risk of getting sick from COVID-19.

  • If others in your home are at particularly high risk for severe illness from COVID-19, consider extra precautions to separate your child from those people.
  • If you are unable to stay home with your child during school dismissals, carefully consider who might be best positioned to provide childcare. If someone at higher risk for COVID-19 will be providing care (older adult, such as a grandparent or someone with a serious underlying medical condition), limit your children’s contact with other people.
  • Consider postponing visits or trip to see older family members and grandparents. Connect virtually or by writing letters and sending via mail.

 

Children and Youth with Special Healthcare Needs

Children with complex, chronic medical conditions, including children with physical, developmental, behavioral, or emotional differences, can have special healthcare needs. It’s not known yet whether all of these children are at higher risk for severe illness from COVID-19.

Although most COVID-19 cases in children are not severe, serious illness that needs to be treated at the hospital still happens. Some data on children reported that the majority who needed hospitalization for COVID-19 had at least one underlying medical condition. The most common underlying conditions reported among children with COVID-19 include chronic lung disease (including asthma), heart disease, and conditions that weaken the immune system. This information suggests that children with these underlying medical conditions may be at risk for more severe illness from COVID-19.

More data are needed to learn which underlying or complex medical conditions may put children at increased risk. CDC is monitoring new information as it becomes available and will provide updates as needed.

Learn more about caring for children with special health care needs during a disaster and people who are at higher risk for severe illness from COVID-19.

In addition to following the recommendations to prevent getting sick and running essential errands, families should take extra steps recommended for persons with higher risk of severe COVID-19 illness and steps outlined for those with potential COVID-19 exposure or confirmed illness.

  • Identify potential alternative caregivers, if you or other regular caregivers become sick and are unable to care for your child. If possible, these alternative caregivers would not be at higher risk of severe illness from COVID-19 themselves.
  • Try to have at least one month of medication and medical supplies on hand. Some health plans allow for a 90-day supply of prescription medications. Consider discussing this option with your child’s healthcare provider.
  • Review any care plans for your child, such as an asthma action plan, and make sure caregivers and backup caregivers are familiar with these plans.
  • If you do not have care plans or an emergency notebook, try to make them. They typically include important information about your child’s medical conditions, how to manage those conditions, how to get in touch with your child’s doctors, allergies, information on medications (names, dosages, and administration instructions), preferences (food and other) or special needs, daily routines and activities, friends, and details about routines that are important to support behavioral and emotional health.
  • Learn if your child’s healthcare providers, including doctors and therapists, have new ways to be contacted or new ways of providing appointments. If they offer telemedicine visits, find out how those are arranged and any additional information you need.
  • If your child receives any support care services in the home that need to be continued, make plans for what you will do if those direct care providers get sick, or if persons in your household are sick.
  • Discuss with the support care agencies and the providers ways to minimize risk for exposure to the virus that causes COVID-19.
    • If your child or other persons in your household are sick with COVID-19 and are able to recover at home, inform your direct care providers and consider postponing or rescheduling services until the criteria for discontinuing home isolation have been met.
    • Ask service providers if they are experiencing any symptoms of COVID-19, or if they have been in contact with someone who has COVID-19.
    • Tell the service provider to:
      • Wear a cloth face covering if they will be close (less than 6 feet) to you or persons in your household. Their cloth face covering helps protect you if they are infected but do not have symptoms.
      • Ask them to wash their hands with soap and water or, if unavailable, use hand sanitizer with at least 60% alcohol when they enter your home, before and after helping your child (dressing, bathing/showering, transferring, toileting and/or diapering, feeding), after handling tissues, and after changing linens or doing laundry. Learn more about proper handwashing.
    • Service providers and families should:
      • Routinely clean and disinfect frequently touched objects and surfaces (counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, bedside tables), and equipment such as wheelchairs, scooters, walkers, oxygen tanks and tubing, communication boards, and other assistive devices. Refer to CDC’s recommendations for Cleaning and Disinfecting Your Home.

Helping children understand and follow recommendations, like social distancing and wearing cloth face coverings, can be challenging if your child has intellectual disabilities, sensory issues, or other special healthcare needs.

  • Keeping children at home and sheltering in place can lower stress created by social distancing and cloth face covering recommendations. Reach out to others for help in running essential errands.
  • Behavioral techniques can be used to address behavioral challenges and to develop new routines. These include social stories, video modeling, picture schedules, and visual cues. Try rewarding your child in small ways with his or her favorite non-food treat or activities to help switch routines and to follow recommendations.
  • Many of the organizations you turn to for information and support around your child’s complex, chronic medical condition may have information on their websites to help families address issues related to COVID-19.
  • Your child’s therapist(s) and/or teachers may also have resources to help successfully introduce new routines to your child.

Additional information on caring for children and on child development specific conditions are available.

Supporting children with special healthcare needs can put additional demands and stress on families, especially during emergency situations. You have likely found ways to manage the stress and challenges unique to your family’s situation. It is important to continue your family’s coping methods, including reaching out to other family members, friends, support groups, and organizations that have been helpful in the past.

See information on ways to cope with stress (such as visiting parks, trails, or open spaces) and making your family stronger.
If you, or someone you care about, are feeling overwhelmed with emotions like sadness, depression, or anxiety, or feel like you want to harm yourself or others:

If your child with special healthcare needs becomes sick with symptoms of COVID-19, contact your child’s healthcare provider. If your child has new or worsening emergency warning signs, such as trouble breathing, pain or pressure in the chest, confusion or inability to wake them up, or bluish lips or face, call 911. If you think your child may have COVID-19, notify the operator so that first responders may be appropriately prepared to protect themselves and others.

Notify your child’s healthcare provider if someone else in your house becomes sick with COVID-19, so they can provide any advice specific for your child.

See additional information if someone in the home is sick with COVID-19 or suspected of having COVID-19.

  • Call your child’s healthcare provider if you have any concerns about your child’s medical conditions. If you need emergency help, call 911.
  • Emergency departments have infection prevention plans to protect you and your child from getting COVID-19 if your child needs care for medical conditions not related to COVID-19. Do not delay getting emergency care for your child’s underlying condition or complex medical condition because you are afraid of getting exposed to COVID-19 when visiting the healthcare setting.

If your child’s healthcare provider tells you to go to the hospital for any health problem, including COVID-19:

  • Ask the healthcare provider to let the hospital know you are coming and to share the important information the hospital will need to know to care for your child.
  • Visiting policies may have changed due to COVID-19. If your child’s hospital policy does not allow an adult to stay with a child, ask your child’s healthcare provider for a statement explaining your child’s need for a familiar adult to be present.
  • Bring your care plans/emergency notebook with you along with paper and pen to write down questions you have during your time at the hospital.

 

Preparing Your Home and Family for COVID-19

Create a household plan of action to help protect your health and the health of those you care about in the event of an outbreak of COVID-19 in your community:

  • Talk with the people who need to be included in your plan, and discuss what to do if a COVID-19 outbreak occurs in your community.
  • Plan ways to care for those who might be at greater risk for serious complications, particularly older adults and those with severe chronic medical conditions like heart, lung or kidney disease.
    • Make sure they have access to several weeks of medications and supplies in case you need to stay home for prolonged periods of time.
  • Get to know your neighbors and find out if your neighborhood has a website or social media page to stay connected.
  • Create a list of local organizations that you and your household can contact in the event you need access to information, healthcare services, support, and resources.
  • Create an emergency contact list of family, friends, neighbors, carpool drivers, health care providers, teachers, employers, the local public health department, and other community resources.

Practice everyday preventive actions to help reduce your risk of getting sick and remind everyone in your home to do the same. These actions are especially important for older adults and people who have severe chronic medical conditions:

  • Avoid close contact with people who are sick.
  • Stay home when you are sick, except to get medical care.
  • Cover your coughs and sneezes with a tissue and throw the tissue in the trash.
  • Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Clean and disinfect frequently touched surfaces and objects (e.g., tables, countertops, light switches, doorknobs, and cabinet handles).
  • Launder items, including washable plush toys, as appropriate and in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry from an ill person can be washed with other people’s items.

Most people who get COVID-19 will be able to recover at home. CDC has directions for people who are recovering at home and their caregivers, including:

  • Stay home when you are sick, except to get medical care.
When to Seek Medical Attention

If you have any of these emergency warning signs* for COVID-19 get medical attention immediately:

  • Trouble breathing
  • Persistent pain or pressure in the chest
  • New confusion or inability to arouse
  • Bluish lips or face

*This list is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning to you.

Call 911 if you have a medical emergency: Notify the operator that you have, or think you might have, COVID-19. If possible, put on a cloth face covering before medical help arrives.

  • Use a separate room and bathroom for sick household members (if possible).
  • Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Provide your sick household member with clean disposable facemasks to wear at home, if available, to help prevent spreading COVID-19 to others.
  • Clean the sick room and bathroom, as needed, to avoid unnecessary contact with the sick person.
  • Avoid sharing personal items like utensils, food, and drinks.

Talk to the school or facility about their emergency operations plan. Understand the plan for continuing education and social services (such as student meal programs) during school dismissals. If your child attends a college or university, encourage them to learn about the school’s plan for a COVID-19 outbreak.

Plan for potential changes at your workplace. Talk to your employer about their emergency operations plan, including sick-leave policies and telework options. Learn how businesses and employers can plan for and respond to COVID-19.

Handwashing is one of the best ways to protect yourself and your family from getting sick. Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol.

Clean and disinfect frequently touched surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.  If surfaces are dirty, clean them using detergent or soap and water prior to disinfection. To disinfect, most common EPA-registered household disinfectants will work. See CDC’s recommendations for household cleaning and disinfection.

CDC recommends handwashing with soap and water for at least 20 seconds or, using alcohol-based hand sanitizer with at least 60% alcohol when soap and water are not available. These actions are part of everyday preventive actions individuals can take to slow the spread of respiratory diseases like COVID-19.

  • When washing hands, you can use plain soap or antibacterial soap. Plain soap is as effective as antibacterial soap at removing germs.
  • If soap and water are not readily available, you can use an FDA-approved alcohol-based hand sanitizer that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label.

CDC does not encourage the production and use of homemade hand sanitizer products because of concerns over the correct use of the ingredientsexternal iconexternal icon and the need to work under sterile conditions to make the product. Local industries that are looking into producing hand sanitizer to fill in for commercial shortages can refer to the World Health Organization guidancepdf iconexternal iconpdf iconexternal icon. Organizations should revert to the use of commercially produced, FDA-approved product once such supplies again become available.

  • To be effective against killing some types of germs, hand sanitizers need to have a strength of at least 60% alcohol and be used when hands are not visibly dirty or greasy.
  • Do not rely on “Do It Yourself” or “DIY” recipes based solely on essential oils or formulated without correct compounding practices.
  • Do not use hand sanitizer to disinfect frequently touched surfaces and objects. See CDC’s information for cleaning and sanitizing your home.

In Case of an Outbreak in Your Community

During an outbreak, stay calm and put your preparedness plan to work. Follow the steps below:

Protect yourself and others.

  • Stay home if you are sick. Keep away from people who are sick. Limit close contact with others as much as possible (about 6 feet).

Put your household plan into action.

  • Stay informed about the local COVID-19 situation. Be aware of temporary school dismissals in your area, as this may affect your household’s daily routine.
  • Continue practicing everyday preventive actions. Cover coughs and sneezes with a tissue and wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use a hand sanitizer that contains 60% alcohol. Clean frequently touched surfaces and objects daily using a regular household detergent and water.
  • Notify your workplace as soon as possible if your regular work schedule changes. Ask to work from home or take leave if you or someone in your household gets sick with COVID-19 symptoms, or if your child’s school is dismissed temporarily. Learn how businesses and employers can plan for and respond to COVID-19.
  • Stay in touch with others by phone or email. If you have a chronic medical condition and live alone, ask family, friends, and health care providers to check on you during an outbreak. Stay in touch with family and friends, especially those at increased risk of developing severe illness, such as older adults and people with severe chronic medical conditions.

Depending on the situation, public health officials may recommend community actions to reduce exposures to COVID-19, such as school dismissals. Read or watch local media sources that report school dismissals or and watch for communication from your child’s school. If schools are dismissed temporarily, discourage students and staff from gathering or socializing anywhere, like at a friend’s house, a favorite restaurant, or the local shopping mall.

Follow the advice of your local health officials. Stay home if you can. Talk to your employer to discuss working from home, taking leave if you or someone in your household gets sick with COVID-19 symptoms, or if your child’s school is dismissed temporarily. Employers should be aware that more employees may need to stay at home to care for sick children or other sick family members than is usual in case of a community outbreak.

CDC makes recommendations, shares information, and provides guidance to help slow down the spread of COVID-19 in the U.S. including guidance for schools and businesses. CDC regularly shares information and provides assistance to state, local, territorial, and tribal health authorities. These local authorities are responsible for making decisions including  “stay at home” or “shelter in place.” What is included in these orders and how they are implemented are also decided by local authorities. These decisions may also depend on many factors such as how the virus is spreading in a certain community.

Please contact your local health department to find out more.

CDC cannot address the policies of any business or organization. CDC shares recommendations based on the best available science to help people make decisions that improve their health and safety. Employers, schools, and organizations may decide to visibly screen for symptoms or perform on-site symptom checks.

If your employer, school, or organization requires you to present documentation regarding COVID-19 before returning to work or school (for example, proof of a negative COVID-19 lab test, if a test was performed, contact your healthcare provider to ask if he or she would be able to provide a form of documentation for you. Documentation of self-isolation and self-quarantine may not be possible.

CDC has guidance for when and how people with COVID-19 can discontinue home isolation: https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-when-sick.html.

CDC also has guidance for what people should do if they think they have been exposed or feel sick: https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/social-distancing.html.

In all cases, follow the guidance of your healthcare provider and local health department. Local decisions depend on local circumstances.

 

Higher Risk

COVID-19 is a new disease and there is limited information regarding risk factors for severe disease. Based on currently available information and clinical expertise, older adults and people of any age who have serious underlying medical conditions might be at higher risk for severe illness from COVID-19.

Based on what we know now, those at high-risk for severe illness from COVID-19 are:

People of all ages with underlying medical conditions, particularly if not well controlled, including:

  • People with chronic lung disease or moderate to severe asthma
  • People who have serious heart conditions
  • People who are immunocompromised
    • Many conditions can cause a person to be immunocompromised, including cancer treatment, smoking, bone marrow or organ transplantation, immune deficiencies, poorly controlled HIV or AIDS, and prolonged use of corticosteroids and other immune weakening medications
  • People with severe obesity (body mass index [BMI] ≥40)
  • People with diabetes
  • People with chronic kidney disease undergoing dialysis
  • People with liver disease

If you are at higher risk of getting very sick from COVID-19, you should:

  • Stock up on supplies
  • Take everyday precautions to keep space between yourself and others
  • When you go out in public, keep away from others who are sick
  • Limit close contact and wash your hands often
  • Avoid crowds, cruise travel, and non-essential travel

If there is an outbreak in your community, stay home as much as possible. Watch for symptoms and emergency signs. If you get sick, stay home and call your doctor. More information on how to prepare, what to do if you get sick, and how communities and caregivers can support those at higher risk is available on People at Risk for Serious Illness from COVID-19.

This list is based on:

  • What we are learning from the outbreak in other countries and in the United States.
  • What we know about risk from other respiratory infections, like flu.

As CDC gets more information about COVID-19 cases here in the United States, we will update this list as needed.

Currently, there is no evidence to show that taking ibuprofen or naproxen can lead to a more severe infection of COVID-19.

People with high blood pressure should take their blood pressure medications, as directed, and work with their healthcare provider to make sure that their blood pressure is as well controlled as possible. Any changes to your medications should only be made by your healthcare provider.

Based on available information, adults aged 65 years and older and people of any age with underlying medical conditions included on this list are at higher risk for severe illness and poorer outcomes from COVID-19. CDC is collecting and analyzing data regularly and will update the list when we learn more. People with underlying medical conditions not on the list might also be at higher risk and should consult with their healthcare provider if they are concerned.

We encourage all people, regardless of risk, to:

  • Take steps to protect yourself and others.
  • Call your healthcare provider if you are sick with a fever, cough, or shortness of breath.
  • Follow CDC travel guidelines and the recommendations of your state and local health officials.

Generally, well-controlled means that your condition is stable, not life-threatening, and laboratory assessments and other findings are as similar as possible to those without the health condition. You should talk with your healthcare provider if you have a question about your health or how your health condition is being managed.

Severity typically means how much impact the illness or condition has on your body’s function.  You should talk with your healthcare provider if you have a question about your health or how your health condition is being managed.

Most people with disabilities are not inherently at higher risk for becoming infected with or having severe illness from COVID-19.  Some people with physical limitations or other disabilities might be at a higher risk of infection because of their underlying medical condition.

  • People with certain disabilities might experience higher rates of chronic health conditions that put them at higher risk of serious illness and poorer outcomes from COVID-19. Adults with disabilities are three times more likely to have heart disease, stroke, diabetes, or cancer than adults without disabilities.

You should talk with your healthcare provider if you have a question about your health or how your health condition is being managed.

 

What CDC is Doing

CDC is working with other federal partners in a whole-of-government response. This is an emerging, rapidly evolving situation and CDC will continue to provide updated information as it becomes available. CDC works 24/7 to protect people’s health. More information about CDC’s response to COVID-19 is available online.

 

COVID-19 and Animals

At this time, there is no evidence that animals play a significant role in spreading the virus that causes COVID-19. Based on the limited information available to date, the risk of animals spreading COVID-19 to people is considered to be low.  A small number of pets have been reported to be infected with the virus that causes COVID-19, mostly after contact with people with COVID-19.

Pets have other types of coronaviruses that can make them sick, like canine and feline coronaviruses. These other coronaviruses cannot infect people and are not related to the current COVID-19 outbreak.

However, since animals can spread other diseases to people, it’s always a good idea to practice healthy habits around pets and other animals, such as washing your hands and maintaining good hygiene. For more information on the many benefits of pet ownership, as well as staying safe and healthy around animals including pets, livestock, and wildlife, visit CDC’s Healthy Pets, Healthy People website.

No. At this time, routine testing of animals for COVID-19 is not recommended.

Although we know certain bacteria and fungi can be carried on fur and hair, there is no evidence that viruses, including the virus that causes COVID-19, can spread to people from the skin, fur, or hair of pets.

However, because animals can sometimes carry other germs that can make people sick, it’s always a good idea to practice healthy habits around pets and other animals, including washing hands before and after interacting with them.

We are still learning about this virus, but it appears that it can spread from people to animals in some situations. Until we learn more about this new coronavirus, you should restrict contact with pets and other animals while you are sick with COVID-19, just like you would with people. When possible, have another member of your household care for your animals while you are sick. If you are sick with COVID-19, avoid contact with your pet, including

  • Petting
  • Snuggling
  • Being kissed or licked
  • Sharing food or bedding

If you must care for your pet or be around animals while you are sick, wash your hands before and after you interact with pets and wear a cloth face covering.

We don’t know for sure which animals can be infected with the virus that causes COVID-19. CDC is aware of a small number of pets, including dogs and cats, reported to be infected with the virus that causes COVID-19, mostly after close contact with people with COVID-19. A tiger at a zoo in New York has also tested positive for the virus.

Recent research shows that ferrets, cats, and golden Syrian hamsters can be experimentally infected with the virus and can spread the infection to other animals of the same species in laboratory settings. Pigs, chickens, and ducks did not become infected or spread the infection based on results from these studies. Data from one study suggested dogs are not as likely to become infected with the virus as cats and ferrets. These findings were based on a small number of animals, and do not show whether animals can spread infection to people.

At this time, there is no evidence that animals play a significant role in spreading the virus that causes COVID-19. Based on the limited information available to date, the risk of animals spreading COVID-19 to people is considered to be low. Further studies are needed to understand if and how different animals could be affected by the virus that causes COVID-19 and the role animals may play in the spread of COVID-19.

We are still learning about this virus and how it spreads, but it appears it can spread from humans to animals in some situations. CDC is aware of a small number of pets, including cats, reported to be infected with the virus that causes COVID-19, mostly after close contact with people with COVID-19. Most of these animals had contact with a person with COVID-19. A tiger at a New York zoo has also tested positive for the virus that causes COVID-19.

At this time, there is no evidence that animals play a significant role in spreading the virus that causes COVID-19. Based on the limited data available, the risk of animals spreading COVID-19 to people is considered to be low. The virus that causes COVID-19 spreads mainly from person to person, typically through respiratory droplets from coughing, sneezing, or talking.

People sick with COVID-19 should isolate themselves from other people and animals, including pets, during their illness until we know more about how this virus affects animals. If you must care for your pet or be around animals while you are sick, wear a cloth face covering and wash your hands before and after you interact with pets.

Walking a dog is important for both animal and human health and well-being. Walk dogs on a leash, maintaining at least 6 feet (2 meters) from other people and animals, do not gather in groups, and stay out of crowded places and avoid mass gatherings. Do not go to dog parks or public places where a large number of people and dogs gather. To help maintain social distancing, do not let other people pet your dog when you are out for a walk.

There is a small number of animals around the world reported to be infected with the virus that causes COVID-19, mostly after having contact with a person with COVID-19. Talk to your veterinarian about any health concerns you have about your pets.

If your pet gets sick after contact with a person with COVID-19, do not take your pet to the veterinary clinic yourself. Call your veterinarian and let them know the pet was around a person with COVID-19. Some veterinarians may offer telemedicine consultations or other plans for seeing sick pets. Your veterinarian can evaluate your pet and determine the next steps for your pet’s treatment and care.

Animals are only being tested in very rare circumstances. Routine testing of animals is not recommended at this time, and any tests done on animals are done on a case by case basis. For example, if the pet of a COVID-19 patient has a new, concerning illness with symptoms similar to those of COVID-19, the animal’s veterinarian might consult with public health and animal health officials to determine if testing is needed.

Based on the limited information available to date, the risk of animals spreading COVID-19 to people is considered to be low. There is no reason to think that any animals, including shelter pets, play a significant role in spreading the virus that causes COVID-19.

CDC does not have any evidence to suggest that imported animals or animal products pose a risk for spreading COVID-19 in the United States. This is a rapidly evolving situation and information will be updated as it becomes available. CDC, the U. S. Department of Agriculture (USDA), and the U.S. Fish and Wildlife Service (FWS) play distinct but complementary roles in regulating the importation of live animals and animal products into the United States.

  • CDC regulates animals and animal products that pose a threat to human health,
  • USDA regulateexternal icon animals and animal products that pose a threat to agriculture; and
  • FWS regulatesexternal icon importation of endangered species and wildlife that can harm the health and welfare of humans, the interests of agriculture, horticulture, or forestry, and the welfare and survival of wildlife resources.

Please refer to CDC’s requirements for bringing a dog to the United States. The current requirements for rabies vaccination apply to dogs imported from high-risk countries for rabies.

Imported animals will need to meet CDC and USDAexternal iconexternal icon requirements for entering the United States. At this time, there is no evidence that companion animals, including pets and service animals, can spread the virus that causes COVID-19. As with any animal introduced to a new environment, animals recently imported should be observed daily for signs of illness. If an animal becomes ill, the animal should be examined by a veterinarian. Call your local veterinary clinic before bringing the animal into the clinic and let them know that the animal was recently imported from another country.

This is a rapidly evolving situation and information will be updated as it becomes available.

Currently, there is no evidence to suggest the virus that causes COVID-19 is circulating in free-living wildlife in the United States, or that wildlife might be a source of infection for people in the United States. The first case of a wild animal testing positive for the virus in the United States was a tiger with a respiratory illness at a zoo in New York City. However, this tiger was in a captive zoo environment ,and public health officials believe the tiger became sick after being exposed to a zoo employee who was infected and spreading the virus.

If a wild animal were to become infected with the virus, we don’t know whether the infection could then spread among wildlife or if it could spread to other animals, including pets. Further studies are needed to understand if and how different animals, including wildlife, could be affected by COVID-19. Because wildlife can carry other diseases, even without looking sick, it is always important to enjoy wildlife from a distance.

Take steps to prevent getting sick from wildlife in the United States:

  • Keep your family, including pets, a safe distance away from wildlife.
  • Do not feed wildlife or touch wildlife droppings.
  • Always wash your hands and supervise children washing their hands after working or playing outside.
  • Leave orphaned animals alone. Often, the parents are close by and will return for their young.
  • Consult your state wildlife agency’s guidance if you are preparing or consuming legally harvested game meat.
  • Do not approach or touch a sick or dead animal – contact your state wildlife agency instead.

Other coronaviruses have been found in North American bats in the past, but there is currently no evidence that the virus that causes COVID-19 is present in any free-living wildlife in the United States, including bats. In general, coronaviruses do not cause illness or death in bats, but we don’t yet know if this new coronavirus would make North American species of bats sick. Bats are an important part of natural ecosystems, and their populations are already declining in the United States. Bat populations could be further threatened by the disease itself or by harm inflicted on bats resulting from a misconception that bats are spreading COVID-19. However, there is no evidence that bats in the United States are a source of the virus that causes COVID-19 for people. Further studies are needed to understand if and how bats could be affected by COVID-19.

Footnotes

1Fever may be subjective or confirmed

2Close contact is defined as—

a) being within approximately 6 feet (2 meters) of a COVID-19 case for a prolonged period of time; close contact can occur while caring for, living with, visiting, or sharing a health care waiting area or room with a COVID-19 case

– or –

b) having direct contact with infectious secretions of a COVID-19 case (e.g., being coughed on)

If such contact occurs while not wearing recommended personal protective equipment or PPE (e.g., gowns, gloves, NIOSH-certified disposable N95 respirator, eye protection), criteria for PUI consideration are met”

See CDC’s updated Interim Healthcare Infection Prevention and Control Recommendations for Persons Under Investigation for 2019 Novel Coronavirus.

Data to inform the definition of close contact are limited. Considerations when assessing close contact include the duration of exposure (e.g., longer exposure time likely increases exposure risk) and the clinical symptoms of the person with COVID-19 (e.g., coughing likely increases exposure risk as does exposure to a severely ill patient). Special consideration should be given to those exposed in health care settings.
