Universal Screening of Severe Acute Respiratory Syndrome Coronavirus 2 with Polymerase Chain Reaction Testing after Rally of Trainee Doctors

There were two rallies of medical students and trainee doctors, where 9,000 participants gathered. We performed polymerase chain reaction (PCR)-based universal screening for the participants using pooling at a tertiary care hospital. Around 609 (94%) of 646 participants underwent PCR tests for severe acute respiratory syndrome coronavirus 2; all of them tested negative. Our data suggested low transmission rates in open air mass gatherings when appropriate personal protective practices were followed.
