Viral shedding

When a virus replicates inside your body and is released (shed) into the environment. At that point, the person who has a virus is infectious, meaning they can pass the virus onto someone else.

SARS-CoV-2 is most infectious when symptoms are worse and viral shedding is high. People who are presymptomatic or asymptomatic are infectious, meaning that viral shedding occurs early on in the infection.
