Students will be allowed to stay in classrooms even if exposed to Covid-19, CDC says

The Centers for Disease Control and Prevention says students can remain in class even after an exposure to Covid-19. 

NBC News reports the CDC no longer recommends that people quarantine after exposure to Covid unless they are in high-risk settings, such as jails, nursing homes and homeless shelters.

Schools, however, are not considered high risk. The CDC now says that in case of an exposure, students and school staff who remain asymptomatic should wear a high-quality mask for 10 days, and get tested on day five.

If someone tests positive for Covid, they must isolate for at least five days -- as that is the most contagious time during a case of Covid, the CDC says. Isolation can end after day five as long as symptoms are improving and any fever is gone; however, masking remains recommended through day 10.

The CDC also says masks are still recommended in indoor areas with high levels of Covid transmission, which includes schools. 

Because quarantining is no longer needed, the CDC has also dropped its "test to stay" recommendations following an exposure.
