What is viral shedding?
Aug. 12, 2020

When a person is infected with a virus, the virus multiplies in the body and can be released into the environment through sneezing, coughing or even speaking. This release is called "shedding" and viral shedding is how COVID-19 is spread from person to person. How long a person who has COVID-19 will shed virus is still unknown.
