CDC: Frequent, Brief Contacts Can Fan Spread Of Coronavirus

The CDC has updated its guidelines, warning that even brief, repeated encounters can spread the disease. This change redefines 'close contact' to include cumulative interactions over 15 minutes within 24 hours. The update is based on new research showing that shorter, repeated contacts can lead to infection. Previously, the CDC recommended quarantine for those in proximity to an infected person for 15 minutes or more. Now, the recommendation includes cumulative contacts over a day.
