Previously, if you were exposed to a person infected with SARS-CoV-2, the recommendation was that you quarantine for 14 days. That’s based on good evidence that most people will have developed symptoms by day 14 and, even if they don’t have symptoms, the risk of being infectious past day 14 is also low.
