Among 101,349 lab-confirmed SARS-CoV-2 cases in Qatar, the risk of reinfection was estimated to be 0.02%, with a reinfection incidence rate of 0.36 per 10,000 person-weeks. Out of 243 patients with at least one positive swab ≥45 days from the first positive swab, 54 (22%) had strong or good evidence for reinfection. Viral genome sequencing confirmed four reinfections out of 12 cases with available genetic evidence.
