U.S. CDC shortens recommended Covid-19 isolation and quarantine time for infected persons without symptoms

The CDC also shortened the recommended time for people to quarantine if they are exposed to the virus to a similar five days if they are vaccinated. People who are fully vaccinated and boosted may not need to quarantine at all, the CDC said.

"Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation from 10 days for people with COVID-19 to five days, if asymptomatic, followed by five days of wearing a mask when around others," the CDC said in a statement.

"The change is motivated by science demonstrating that the majority of SARS-CoV-2 transmission occurs early in the course of illness, generally in the 1-2 days prior to onset of symptoms and the 2-3 days after. Therefore, people who test positive should isolate for five days and, if asymptomatic at that time, they may leave isolation if they can continue to mask for five days to minimize the risk of infecting others."   ...
