Masks are recommended by government organizations as a simple barrier to help reduce the spray of droplets when coughing, sneezing or talking. Wearing masks is particularly important when social distancing is not feasible. For that reason, many workplaces and public buildings now require masks to reduce the spread of disease in our fight against COVID-19. Testing worn masks presents a unique opportunity to collect information about the presence of SARS-CoV-2 in a population.
