The Centers for Disease Control and Prevention streamlined its guidance Thursday for keeping COVID-19 in check, de-emphasizing social distancing, nixing screening tests for those without symptoms and no longer recommending that people who aren’t current on vaccines should quarantine after being exposed to the virus.

The CDC had previously urged people who are unvaccinated, or hadn’t had a booster shot to “stay home and quarantine for at least five full days,” after exposure, while those current on the vaccine or who had recovered from COVID-19 in the past 90 days did not have to stay home unless they had symptoms.
