Tracking changes in SARS-CoV-2 transmission with a novel outpatient sentinel surveillance system in Chicago, USA
Abstract
In this study, the authors develop a method for estimation of SARS-CoV-2 community transmission rates based on a sentinel population of people seeking outpatient testing with recent symptom onset. This method has fewer operational delays than methods based on hospital data, and may be subject to fewer biases.
