COVID-19 spreads from person to person through droplets in the air. There are large droplets and small droplets. Large droplets come from the lungs of one person during coughing or sneezing, and are then inhaled into the nose or mouth by a nearby person.
COVID-19 can also spread through very small droplets in the air-smaller than those expelled in a cough or sneeze. Activities like singing and loud voice produce these types of droplets and should therefore be avoided. COVID-19 can spread from one person to another even if the person does not show any symptoms of the disease.
