Age and prior exposure influences SARS-CoV-2 virus shedding, affects incubation period

This study found that age and prior exposure influences viral shedding dynamics of SARS-CoV-2 dynamics, and older individuals and those with more exposure exhibit lower shedding. This is important because the speed of shedding correlates with the incubation period, which can aid in COVID-19 response planning. This work was supported by a Stand Up To Cancer‐LUNGevity-American Lung Association Lung Cancer Interception Dream Team Translational Research Grant.
