Abstract
To determine optimal quarantine duration, we evaluated time from exposure to diagnosis for 107 close contacts of severe acute respiratory syndrome coronavirus 2 Omicron variant case-patients. Average time from exposure to diagnosis was 3.7 days; 70% of diagnoses were made on day 5 and 99.1% by day 10, suggesting 10-day quarantine.
Keywords: 2019 novel coronavirus disease; COVID-19; Omicron; SARS-CoV-2; VOC; coronavirus disease; respiratory infections; severe acute respiratory syndrome coronavirus 2; variant; viruses; zoonoses.
