The Centers for Disease Control and Prevention has changed the amount of time it would take for someone to be considered a close contact of a person with COVID-19. Previous language defined a close contact as someone who spent at least 15 minutes within 6 feet of a confirmed case. The CDC now defines a close contact as someone who was within 6 feet of an infected person for a total of 15 minutes or more over a 24-hour period. People considered close contacts are supposed to quarantine and get tested for the virus. In a study published Wednesday, the CDC and Vermont health officials found that multiple, short and nonconsecutive exposures to persons confirmed to have COVID-19 led to transmission of the virus. During the contact tracing investigation, it was discovered that the coronavirus was transmitted to a correctional facility employee who interacted with individuals later found to be positive for the coronavirus.
