Former Surgeon General Jerome Adams advised against following recent COVID-19 guidance from the Centers for Disease Control and Prevention (CDC) asserting that some people infected with the virus could end their quarantine after just five days.

“I love the CDC. Grew up wanting to work there and have been one of their most ardent defenders. I never dreamed the day would come when I would advise people NOT to follow their guidance,” Adams said in a tweet on Tuesday. “They wouldn’t even follow it for their own family.”
