Mayo Clinic Q&A: CDC Updates Close Contact Guidelines

The Centers for Disease Control and Prevention (CDC) has updated its guidelines for defining close contact with a person who is positive for COVID-19. Previously, close contact was defined as occurring when someone was within 6 feet of an infectious person for 15 consecutive minutes. Now close contact includes people who were within 6 feet for a total of 15 minutes over a 24-hour period, as the CDC now advises that repeated, brief encounters also carry a risk of transmission.
