Researchers estimate that people who get infected with the coronavirus can spread it to others 2 to 3 days before symptoms start and are most contagious 1 to 2 days before they feel sick.

Anyone who has had close contact with someone with COVID-19 should stay home for 14 days after their last exposure to that person.

On average, symptoms showed up in the newly infected person about 5 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14. In rare cases, symptoms can show up after 14 days.4 days ago

Symptoms may include: fever or chills; cough; shortness of breath; fatigue; muscle and body aches; headache; new loss of taste or smell; sore throat; congestion or runny nose; nausea or vomiting; diarrhea.

Anyone who has COVID-19 should isolate for 10 full days, according to current guidance from the U.S. Centers for Disease Control and Prevention.

People with COVID-19 can spread the virus to other people for 10 days after they develop symptoms, or 10 days from the date of their positive test if they do not have symptoms. The person with COVID-19 and all members of the household should wear a well-fitted mask and consistently, inside the home.

If both of you are healthy and feeling well, are practicing social distancing and have had no known exposure to anyone with COVID-19, touching, hugging, kissing, and sex are more likely to be safe.

Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. An infection of a fully vaccinated person is referred to as a “vaccine breakthrough infection.”
