Symptoms usually appear 2 to 6 days after exposure to the virus. However, it sometimes takes longer — up to 14 days
Can a person who has been infected with COVID-19 get infected again?
The immune system responds to COVID-19 infection by stimulating white blood cells called lymphocytes to form antibodies that fight the infection. These antibodies and lymphocytes retain a temporary protective effect against reinfection. But it is only temporary. There have been many confirmed cases of reinfection with COVID-19. In other words, a person got sick with COVID-19, recovered, and then became infected again.
When are people infected with COVID-19 most likely to be contagious?
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.
Can I get COVID-19 twice?
The protection you get may be unpredictable, according to doctors, and those who have more severe bouts of COVID-19 typically end up with more robust protection from the virus. To prevent COVID-19 reinfections, health officials say vaccination is the best bet.
