SARS-CoV-2 typically spreads from person to person through respiratory droplets. When an infected person sneezes, coughs, talks, or breathes, it releases droplets. Someone nearby can inhale the droplets into their lungs, or the droplets can land in their eyes, nose, or mouth, infecting them.
Infected droplets also can land on surfaces or objects. When a person touches those surfaces and then touches their nose, mouth, or eyes without washing their hands, this also can cause an infection.
If a person is infected, they can spread the coronavirus even if they don't have symptoms of COVID-19.
