The CDC states that, "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 or sneezes.
These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs."
To prevent the spread of the virus:
Clean your hands often
Make sure to wash for at least 20
seconds with soap or 60%- 90%
alcohol by volume sanitizer.
Avoid close contact
Stay home if you’re sick
Cover coughs and sneezes
Wear a facemask if you are sick
Only wear a mask if you yourself are sick or
if you are caring for someone who is.
Clean and disinfect
