Presentation Transcript
Staph aureus are bacteria that commonly cause skin infections.
  • 20 to 30% of healthy people have Staph on their skin.
  • Staph are resistant to some antibiotics, but all Staph infections can be treated with one or more antibiotics.
  • Some populations, like athletes, military recruits, children, and prisoners are at higher risk of Staph infections.
  • The risk of infection is increased when there are cuts in the skin, close skin-to-skin contact, crowded living conditions, poor hygiene, and contaminated items and surfaces.
Staph infection can be prevented through practicing good hygiene:1. Keep hands clean by washing with soap and water or using an alcohol-based hand sanitizer. 2. Keep cuts and scrapes clean and covered with a bandage until healed. 3. Avoid contact with other people’s wounds and bandages 4. Avoid sharing personal items such as towels or razors.
  • Employees and students with Staph infections do not need to be excluded from work or school if their wounds are clean and covered.
