‘The US CDC published updated guidance regarding quarantine after known exposure to SARS-CoV-2. The CDC’s quarantine guidance continues to direct individuals to quarantine for 14 days* after the last known exposure to a COVID-19 patient, but the updated guidance provides options to shorten the quarantine period. Under the new guidance, individuals who do not exhibit any COVID-19 symptoms can end their quarantine as early as Day 10* without testing and Day 7* if they have a negative diagnostic test result (RT-PCR or antigen test). Importantly, for individuals who get tested, the test specimen should be collected within 48 hours of ending the quarantine period, which means that individuals should be tested at Day 5 or later. Even if a test conducted on Day 5 or 6 is returned before Day 7, in no case should quarantine be terminated prior to Day 7.’
