The Centers for Disease Control and Prevention (CDC) has updated its guidelines for defining close contact with a person who tests positive for COVID-19. Previously, close contact was defined as occurring when someone was within 6 feet (about 2 meters) of an infectious person for 15 consecutive minutes. Now close contact includes people who were within 6 feet (about 2 meters) for a cumulative total of 15 minutes over a 24-hour period, as the CDC now advises that repeated, brief encounters also carry a risk of transmission.
Gregory A. Poland, M.D., an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, discusses the updated information from the CDC and the latest information from the Food and Drug Administration on COVID-19 treatments and vaccines.
