SARS-CoV-2, the causative agent of COVID-19, can spread from individuals with pre-symptomatic, symptomatic, and asymptomatic infections. As such, the COVID-19 pandemic has created a global public health crisis. Re-opening of societies and the control of virus spread will be facilitated by wide-scale surveillance. This talk describes development of an immunochromatographic assay for rapid detection of SARS-CoV-2 antigen, highlighting analytical and clinical performances. The talk also describes mathematical models of COVID-19 transmission in a major U.S. city, demonstrating that effective surveillance depends largely on frequency and coverage of testing.
