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. Each health department determines community spread differently based on local conditions. For information on community spread in your area, please visit your local health department’s website.

COVID-19 Community Levels are a tool to help communities decide what prevention steps to take based on the latest data. Levels can be low, medium, or high and are determined by looking at the percent of hospital beds being used by patients with COVID-19, the rate of new hospital admissions in the population, and the rate of new COVID-19 cases in the community. People can take different steps depending on the COVID-19 Community Level in their area.

Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition associated with COVID-19 where different body parts can become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal organs. For information, see MIS-C.

Look for emergency warning signs* of COVID-19. If someone is showing any of these signs, seek emergency medical care immediately:

• Trouble breathing
• Persistent pain or pressure in the chest
• New confusion
• Inability to wake or stay awake
• Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone

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

You should get tested for COVID-19:

• If you have symptoms of COVID-19.
• At least 5 days after you last had close contact with someone with COVID-19, even if you don’t develop symptoms (you do not have to get tested if you have already tested positive for COVID-19 in the past 90 days.)
• You are going to an indoor event or a gathering
• Before and after travel
• For COVID-19 screening (schools, workplaces, congregate settings, etc.)

For more information on testing, see

• Testing for COVID-19
• Self-Testing at Home or Anywhere
• Test for Current Infection
• Test for Past Infection

Yes, it is possible. A negative test does not rule out an infection.

• If you have a negative test but have symptoms of COVID-19, you may have tested before the virus was detectable or you may have another illness, such as the flu.
• If you do not have symptoms of COVID-19 but were a close contact to someone with COVID-19 and you tested negative 5 days after exposure, that means the virus was not detected by the test. You are likely not infected, but an infection cannot be completely ruled out.

Even if you test negative, you still should take steps to protect yourself and others. See Testing for Current Infection for more information.

Discussions with health department staff are confidential. This means that your personal and medical information will be kept private and only shared with those who may need to know, like your health care provider.

If you have been diagnosed with COVID-19, your name will not be shared with your close contacts. If you meet the local criteria to be interviewed, the health department will only notify people you were in close contact with that they might have been exposed to COVID-19. Each state and jurisdiction use their own method for collecting and protecting health information. To learn more, contact your state or local health department.

For COVID-19, a close contact is anyone who was less than 6 feet away from an infected person for a total of 15 minutes or more over a 24-hour period (for example, three individual 5-minute exposures for a total of 15 minutes) – excluding K-12 school settings. An infected person can spread COVID-19 starting from 2 days before they have any symptoms (or, if they are asymptomatic, 2 days before their specimen that tested positive was collected), until they meet the criteria for discontinuing isolation. You can use this tool to help determine who is a close contact: How to Determine a Close Contact for COVID-19.

If you have COVID-19, tell your close contacts you have COVID-19 so that they can follow CDC guidance for close contacts. Recommendations for close contacts to quarantine, get tested, and wear well-fitting masks after exposure to COVID-19 will vary depending on vaccination status and history of prior COVID-19 diagnosis within the past 90 days. See COVID-19 Quarantine and Isolation for more information By letting your close contacts know they may have been exposed to COVID-19, you are helping to protect them and others within your community.

You can call, text, or email your contacts. If you would like to stay anonymous, there is also an online tool that allows you to tell your contacts by sending out emails or text notifications anonymously (www.tellyourcontacts.orgexternal icon).

Except in K-12 school settings, a person is still considered a close contact even if one or both people wore a mask when they were together.

If you have been in close contact with someone who has COVID-19, you should be tested at least 5 days after your last close contact, even if you do not have symptoms of COVID-19. If you have tested positive for COVID-19 in the past 90 days, you should not be tested again. The health department may be able to provide resources for testing in your area.

For more information, see COVID-19 Contact Tracing.

Watch for or monitor your symptoms of COVID-19. If your symptoms worsen or become severe, seek medical care.

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.

Do not wipe or bathe your pet with chemical disinfectants, alcohol, hydrogen peroxide, or other products, such as hand sanitizer, counter-cleaning wipes, or other industrial or surface cleaners. Talk to your veterinarian if you have questions about products for bathing or cleaning your pet. If your pet gets hand sanitizer on their skin or fur, rinse or wipe down your pet with water immediately. If your pet ingests hand sanitizer (such as by chewing the bottle) or is showing signs of illness after use, contact your veterinarian or pet poison control immediately.

Pets infected with the virus that causes COVID-19 may or may not get sick. Of the pets that have gotten sick, most only had mild illness and fully recovered. Serious illness in pets is extremely rare.  Most pets that have gotten sick from the virus that causes COVID-19 were infected after close contact with a person with COVID-19. Pets may have fever, coughing, difficulty breathing or shortness of breath, lethargy (unusual lack of energy or sluggishness), sneezing, runny nose, eye discharge, vomiting, or diarrhea. If your pet is sick and you think it might be from the virus that causes COVID-19, talk to your veterinarian.

Currently, there is no evidence to suggest that wildlife might be a source of infection for people in the United States. The risk of getting COVID-19 from wild animals is low. For more information on handling wildlife, see Reducing the Risk of SARS-CoV-2 Spreading between People and Wildlife.

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 bats in the United States. 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..
