What is asymptomatic transmission?

ANSWER

Asymptomatic means no symptoms. When someone has an infection, there is a period of time after they catch the germ before they have symptoms. This is called the incubation period. In some cases, people may catch the infection and never have any symptoms. Even with no symptoms, it’s possible to spread an infection. For example, the flu is contagious a day before someone develops symptoms. For COVID-19, the disease caused by the novel coronavirus, it’s most contagious when someone has symptoms, but it’s still possible to spread the infection from person to person even with no symptoms.
