CDC Announces Changes to Recommended Isolation and Quarantine Period
On December 27, 2021, the Centers for Disease Control and Prevention (CDC) shortened the recommended isolation time for COVID-19 positive individuals from 10 days to 5 days from the positive test date, if asymptomatic, followed by 5 days of wearing a mask around others. This applies regardless if the individual is vaccinated. If the individual has a fever, they should continue isolation until the fever ends.
Additionally, the CDC shortened the recommended quarantine time for those exposed to a person that is COVID-19 positive. Those unvaccinated or 6 months out from their second vaccine does (or more than 2 months after the Johnson and Johnson vaccine) should quarantine for 5 days followed by strict mask use for an additional 5 days. Those exposed but unable to quarantine for 5 days should wear a mask around others for 10 days after exposure. Individuals that received their booster vaccine dose do not need to quarantine following an exposure, but should wear a mask for 10 days after exposure.
It’s important that the mask is well-fitting.
Anyone exposed should also test at day 5 after exposure. However, if symptomatic, immediately quarantine until a negative test.
The CDC reported that these changes are supported by science showing that a majority of COVID-19 transmissions generally occur early in the 1-2 days prior to the onset of symptoms and 2-3 days after. For details, see the CDC’s media statement
