When it comes to the duration of COVID-19 infection, the evidence suggests that people with mild to moderate symptoms remain contagious for no more than 10 days after the onset of symptoms. However, research has aligned more closely with CDC isolation guidelines, which assume that most people will stop being infectious after five days. A pre-impression study of nearly 100 college students vaccinated at Boston University suggests that most were no longer contagious after five days. Therefore, there is a chance that people may still be infectious beyond their seven-day isolation period if they still have symptoms.
After ten days, most people are no longer contagious. Multiple studies have shown that there is very little or no transmission after day ten, regardless of the variant. It is important to note that the period of infection with COVID-19 varies from person to person. Most people with COVID-19 will have a mild illness and recover within a few days. However, it is important to follow the CDC guidelines and isolate for at least seven days if you have been exposed to the virus or are showing symptoms.
This will help reduce the spread of the virus and protect those around you.
