Coronavirus testing centers such as those employed in China, South Korea and Israel have shown to be valid measures to contain the epidemic [5] However, although COVID-19 transmission by asymptomatic subjects is a critical factor for ensuring an effective public health response to the epidemic, the best method of identifying asymptomatic infections is still unclear. The decision not to search for SARS-COV-2 in people with mild symptoms and not to include them in surveillance programmes is at least questionable, particularly because the future relaxation of containment measures will require even more active surveillance in order to ensure the early detection of new cases or clusters. ./cache/cord-310149-8idvf79g.txt ./txt/cord-310149-8idvf79g.txt
