Crowded living conditions, like hospitals and prisons
In health care centers, people who carry MRSA are sometimes isolated from other patients to prevent the bacteria from spreading.
According to the CDC, here are some of the best ways to prevent MRSA:
Wash your hands thoroughly. Use soap and water or an alcohol-based hand sanitizer. Experts suggest that you wash your hands for as long as it takes you to recite the alphabet.
Cover cuts and scrapes with a clean bandage. This will help the wound heal. It will also prevent you from spreading bacteria to other people.
Do not touch other people's wounds or bandages.
Do not share personal items like towels or razors. If you use any shared gym equipment, wipe it down before and after you use it. Drying clothes, sheets, and towels in a dryer -- rather than letting them air dry -- helps kill bacteria.
