How Coronavirus Spreads
COVID-19 is a new disease and we are still learning how it spreads, the severity of illness it causes, and to what extent it may spread in the United States.

*Person-to-person spread
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.
*Can someone spread the virus without being sick?
People are thought to be most contagious when they are most symptomatic (the sickest).
Some spread might be possible before people show symptoms; there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.
*Spread from contact with contaminated surfaces or objects
It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.
