There is currently no vaccine to prevent coronavirus disease 2019 (COVID-19).

The best way to prevent illness is to avoid being exposed to this virus.

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, sneezes or talks.
• These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
• Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms.
