Actions You Can Take Based on Current Activity Level

  • Get vaccinated against respiratory illnesses. COVID-19 and flu vaccines are recommended for people 6 months and older. RSV vaccine is recommended for people at high risk—talk with your health care provider for details. Go to vaccines.gov for a location near you.
  • Wash hands often with soap and water for 20 seconds, especially after coughing or sneezing.
  • Cover coughs and sneezes with a tissue or your elbow.
  • Stay home if you are sick with respiratory illness to prevent spreading it to others. Return to normal activity when your symptoms have improved, and you are fever free for 24 hours.

  • Consider wearing a well-fitted mask when around others indoors.
  • Avoid crowded areas when possible.
  • Improve air quality by bringing in fresh air from outside (opening doors or windows or using exhaust fans), purifying air indoors, or gathering outdoors.
