While people become less contagious over time, they are still contagious with COVID for an average of eight days. That may vary depending on factors including underlying health conditions and the severity of illness.
“A big study came out in the fall of 2023 which showed that most people are the most contagious on day four of symptoms with COVID and then it wanes from there,” said Dr. Roberts. While people become less contagious over time, they are still contagious with COVID for an average of eight days.
Consider staying away from people at high risk of getting very sick until: 10 days have passed since your symptoms started, 10 days have passed since you tested positive (if you never developed symptoms), or. You test negative for COVID-19 with an antigen test (such as an at-home test)
People with COVID-19 can be infectious from 1–2 days before and up to 8–10 days after symptoms begin. The majority of transmission appears to occur during the early periods of infection, particularly in the 1–2 days before symptoms start and within the first few days of symptom onset.
Avoid close contact with those who are sick. Stay home if you are ill. Cover your cough and sneezes with tissue. Wash hands frequently with soap and water.

Updated Guidance: The updated Respiratory Virus Guidance recommends that people stay home and away from others until at least 24 hours after both their symptoms are getting better overall, and they have not had a fever (and are not using fever-reducing medication).
Stopping the Spread of COVID-19 to Others Stay home unless you need medical care. Don't go to work or school and avoid public places like stores. Stay away from others. Wear a mask. Wash your hands. Call your close contacts.
You have had no fever for at least 72 hours (that is three full days of no fever without the use medicine that reduces fevers) AND. Other symptoms have improved (for example, when your cough or shortness of breath have improved) AND. At least seven days have passed since your symptoms first appeared.
You must monitor yourself for symptoms, wear a mask at all times around others, wash hands, and stay at least 6 feet from others for 14 days after exposure.
