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, 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.
• Maintaining good social distance (about 6 feet) is very important in preventing the spread of COVID-19.

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. This is not thought to be the main way the virus spreads, but we are still learning more about this virus. CDC recommends people practice frequent “hand hygiene,” which is either washing hands with soap or water or using an alcohol-based hand rub. CDC also recommends routine cleaning of frequently touched surfaces.
