The Center for Disease Control and the World Health Organization recommend several basic measures to help prevent the spread of
- Wash your hands often and for at least 20 seconds.
- Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
- Clean and disinfect frequently touched objects.
- Stay home when you are sick.
- Contact a health worker if you have symptoms: fever and a dry cough are most common.
- DON’T touch your face.
- DON’T travel if you have a fever and cough.
- DON’T wear a face mask if you are well.
The science, according to the CDC, says that surgical masks won’t stop the wearer from inhaling small airborne particles, which can cause infection. Nor do these masks form a snug seal around the face. The CDC recommends surgical masks only for people who already show symptoms of coronavirus and must go outside, since wearing a mask can help prevent spreading the virus by protecting others nearby when you cough or sneeze. The agency also recommends these masks for caregivers of people infected with the virus.
