Staying Safe During COVID-19

Know How it Spreads


  • 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.


Take steps to protect yourself


Clean your hands often

  • Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.

  • If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.

  • Avoid touching your eyes, nose, and mouth with unwashed hands.


Avoid close contact


Take steps to protect others


Stay home if you’re sick


Cover coughs and sneezes

  • Cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow.

  • Throw used tissues in the trash.

  • Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not readily available, clean your hands with a hand sanitizer that contains at least 60% alcohol.


Wear a facemask if you are sick

  • If you are sick: You should wear a facemask when you are around other people (e.g., sharing a room or vehicle) and before you enter a healthcare provider’s office. If you are not able to wear a facemask (for example, because it causes trouble breathing), then you should do your best to cover your coughs and sneezes, and people who are caring for you should wear a facemask if they enter your room. Learn what to do if you are sick.

  • If you are NOT sick: You do not need to wear a facemask unless you are caring for someone who is sick (and they are not able to wear a facemask). Facemasks may be in short supply and they should be saved for caregivers.


Clean and disinfect

  • Clean AND disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.

  • If surfaces are dirty, clean them: Use detergent or soap and water prior to disinfection.
