Asymptomatic SARS-CoV-2 infections vary with age and geographical location

A distinguishing feature of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) compared to severe acute respiratory syndrome (SARS) is that it is spread not only via symptomatic people but also asymptomatic and pre-symptomatic people. Asymptomatic cases are becoming of increasing concern due to the potential of people unknowingly causing local outbreaks within their communities. In …
