The virus that causes COVID-19 spreads from person to person. It can be transmitted through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are in close contact (within about 6 feet) and can be inhaled into the lungs. It can also be spread when a person touches a contaminated surface and then touches their own mouth or nose, however this is not the main way the virus spreads.
