CDC is updating the recommended quarantine period for anyone in the general public who is exposed to COVID-19. For people who are unvaccinated or are more than six months out from their second mRNA dose (or more than 2 months after the J&J vaccine) and not yet boosted, CDC now recommends quarantine for 5 days followed by strict mask use for an additional 5 days.
Alternatively, if a 5-day quarantine is not feasible, it is imperative that an exposed person wear a well-fitting mask at all times when around others for 10 days after exposure.
Individuals who have received their booster shot do not need to quarantine following an exposure, but should wear a mask for 10 days after the exposure.
For all those exposed, best practice would also include a
test for SARS-CoV-2 at day 5 after exposure. If symptoms occur,
individuals should immediately quarantine until a negative test confirms
symptoms are not attributable to COVID-19.
