How do asymptomatic people (who don’t cough) transmit COVID-19?
gpt
You're still producing new virions if you are asymptomatic. Most likely happening in your mouth/throat. If an asymptomatic person touches their mouth and then any other surface, it is contaminated for several days. Also, most people clear their throat on a daily basis or has a one off cough every now and then, that could spread the disease as well.
