What is COVID-19?

Coronavirus Disease 2019 (COVID-19) is a new disease, and we are still learning about how it spreads and the severity of illness it causes. The virus that causes COVID-19 is believed to spread person-to-person between people who are in close contact (being within about 6 feet) with one another. Some people without symptoms may be able to spread the virus.

The virus likely spreads primarily through saliva or mucus droplets produced when an infected person coughs, sneezes, or talks. This is somewhat like how the flu (influenza) and other infections such as the common cold spread.

These droplets can land in the mouths or noses of people who are nearby or possibly be breathed in. Droplets can remain on surfaces such as countertops and doorknobs for hours to days.
