Saliva detection of SARS-CoV-2 for mitigating company outbreaks: A surveillance experience, Milan, Italy, March 2021

Abstract

Monitoring the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) communitywide transmission with a suitable and effective sampling method would be of great support for public health response to the spreading due to asymptomatic subjects in the community. Here, we describe how using saliva samples for SARS-CoV-2 detection has allowed for a weekly surveillance of a small business company and the early detection of coronavirus disease 2019 cases. As on 23rd March, two cases were detected and investigated, and control measures were rapidly applied.
