The Centers for Disease Control and Prevention has substantially revised its COVID-19 guidance. Social distancing guidance of six feet is no more. Quarantining is no longer recommended if you were exposed to COVID-19. Instead, the CDC recommends that you wear a high-quality mask for 10 days and get tested on day 5. Isolation recommendations for those who are sick or test positive for COVID-19 are revised yet again. Breakthrough cases are no longer considered rare and vaccination status differentiation is out.
