If HCWs are indeed at high risk of contracting and carrying SARS-CoV-2 virus, then the current HCWs virological surveillance for COVID-19 should be able to detect SARS-CoV-2-positive cases among HCWs. Therefore, we reviewed the HCWs surveillance results at our hospital. Our hospital is one of major medical centers designated for COVID-19 treatment in Taipei, and successfully treated 29 laboratory-confirmed COVID-19 cases during the period from February 4, 2020 to July 6, 2020. 5 Since March 31, 2020, in consistent with Taiwan Central Epidemic Command Center's HCWs surveillance policy, 5 all HCWs who developed fever or any respiratory symptoms were required to be tested for SARS-CoV-2 regardless of the presence of occupational exposure history or not .
