STAT News: CDC expands definition of ‘close contacts,’ after study suggests Covid-19 can be passed in brief interactions

STAT News: CDC expands definition of ‘close contacts,’ after study suggests Covid-19 can be passed in brief interactions. “Previously, the CDC described a close contact as someone who spent 15 minutes or more within six feet of someone who was infectious. Now, the agency says it’s someone who spent a cumulative 15 minutes or more within six feet of someone who was infectious over 24 hours, even if the time isn’t consecutive, according to an agency spokesperson.”
