What is COVID-19?
COVID-19 is a respiratory illness caused by the SARS-CoV-2 virus. The virus is constantly changing and can lead to the emergence of variants that may have new traits, like different ways of spreading or how sick it makes people.
Who gets COVID-19 and how?
COVID-19 is caused by a strain of the coronavirus. Coronavirus is a common virus that can cause cold-like symptoms. Many people with COVID-19 have no symptoms, or think they just have a common cold.
The virus that causes COVID-19 spreads through the air when a person coughs, sneezes, sings, or talks. It can also spread when droplets land on surfaces and then are rubbed into the eyes, nose, or mouth. COVID-19 most commonly spreads during the first week of the infection. Anyone infected with COVID-19 can spread it, even if they do NOT have symptoms.
People who are at high risk for getting very sick or requiring medical attention if they get COVID-19 are premature infants, older adults, people with chronic health conditions, and people with weakened immune systems.
What are the symptoms of COVID-19?
Children with COVID-19 usually have mild symptoms or no symptoms. A child with COVID-19 may have one or more of these symptoms:
- Fever
- Runny nose and congestion
- Sore throat
- Cough
- Headache
- Tiredness
- Muscle pain
- Loss of taste or smell
- Nausea or Vomiting
- Diarrhea
Children with COVID-19 generally don’t get as sick as adults. However, a rare but serious concern is Multisystem Inflammatory Syndrome in Children (MIS-C). MIS-C causes inflammation in different parts of the body, like the heart, lungs, brain, and digestive tract. It usually occurs two to six weeks after a child gets COVID-19. Symptoms include abdominal pain, vomiting, diarrhea, dizziness, and rash. Children with these symptoms should be seen by a health care provider to be evaluated for MIS-C.

Should a child with COVID-19 stay home?
Children should stay home if they have COVID-19 symptoms.
- If a child tests positive for COVID-19, they should stay home until they are fever free for 24 hours and their symptoms are mild and improving.
- The California Department of Public Health recommends that children mask around other people indoors for the 10 days after they became sick or tested positive. They can remove their mask sooner than 10 days if they have two sequential negative tests at least one day apart.
- Avoid contact with people at higher risk for COVID-19 for 10 days, including the elderly.
Most children with COVID-19 get better by resting at home, staying hydrated, and managing their symptoms. Children with COVID-19 may need to see their health care provider if they have a chronic illness, their symptoms are restricting their activity, or their symptoms are getting worse. A child’s health care provider may suggest over-the-counter medications for fever, cough, and congestion.
Children should see a health care provider immediately if they have difficulty breathing, confusion, chest pain, inability to stay awake, or changes in the skin, lip, or nail color (e.g., they become pale, gray, or blue).
Tips to reduce the risk of COVID-19
Practicing healthy habits can reduce the likelihood of getting COVID-19:
- Use the Daily Health Check, exclusion policy, and staff health policy to guide health and safety decisions in your program.
- Practice good handwashing.
- Stay up-to-date with vaccinations.
- Show children how to cover their cough and sneeze.
- Follow the routine schedule for cleaning, sanitizing, and disinfecting in Caring for Our Children Appendix K
- Ventilate the indoor space by using an exhaust fan, open windows, and/or portable air cleaner; maintain and check the program’s HVAC system and use MERV 13+ filters.
- Spend time outdoors, when possible. See recommendations about Active Outdoor Play for more information.
What to do if a child has been exposed to someone with COVID-19:
- Monitor for COVID-19 symptoms.
- Test the child for COVID-19 if they develop symptoms, according to the California Department of Public Health.
