The CDC recommends using common sense prevention practices:
Wash your hands often with soap and water for at least 20 seconds, especially before eating; and after blowing your nose, coughing, or sneezing.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Stay home when you are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
For people at higher risk of getting very sick from COVID-19, the CDC recommends:
Taking everyday precautions to keep space between yourself and others
In public, keep away from others who are sick, limit close contact, and wash hands often
Avoid crowds as much as possible
During a COVID-19 outbreak in your community, stay home as much as possible to further reduce your risk of being exposed.
