Guidance from the CDC:
To help prevent the spread of COVID-19:
Wear a mask to protect yourself and others and stop the spread of COVID-19.
Stay at least 6 feet (about 2 arm lengths) from others who don’t live with you.
Clean your hands often, either with soap and water for 20 seconds or a hand sanitizer that contains at least 60% alcohol.
Avoid close contact with people who are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
Monitor your health daily.
