People who test positive for the coronavirus need to isolate themselves for only five days if they don’t show symptoms, the Centers for Disease Control and Prevention said Monday. This cuts in half the earlier recommendation of 10 days of isolation.
Data shows that the majority of coronavirus transmission “occurs early in the course of illness,” the CDC explained — generally in the one or two days before symptoms begin and two or three days after.
“Therefore, people who test positive should isolate for 5 days and, if asymptomatic at that time, they may leave isolation if they can continue to mask for 5 days to minimize the risk of infecting others,” the CDC said in a statement.
The CDC has also updated its recommended quarantine period for people exposed to the virus. It says unvaccinated people should quarantine for five days, followed by five days of “strict mask use.” Exposed people who are more than six months past their second dose of the Pfizer-BioNTech or Moderna vaccines, or two months out from a Johnson & Johnson vaccine, should also quarantine for five days.
People who have gotten their booster shot don’t need to quarantine after exposure but should wear a mask for the next 10 days.
