COVID-19 is a new disease, and scientists are still learning about it, including the severity of illness it causes, and to what extent it may spread in the U.S. Currently, COVID-19 seems to be spreading easily and sustainably in the community.
The virus is thought to spread mainly from person-to-person:
- Between people who are in close contact with one another (within about 6 feet).
- Through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
People are thought to be most contagious when they are most symptomatic (the sickest).
