Coronavirus (COVID 19) Spreads

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)
+ Via 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.

Spread from contact with infected 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.
When does spread happen?
+ 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 with this new coronavirus, but this is not thought to be the main way the virus spreads.

How efficiently does the virus spread?
How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious (like measles), while other viruses are less so. Another factor is whether the spread continues over multiple generations of people (if spread is sustained).
