Home > Health Library > Staph Infection
Staphylococcus aureus (staph) is a type of bacteria that can cause infections. Staph bacteria normally live on the skin. They don't usually cause problems. They only become a problem when they cause infection. The infection has a higher chance of becoming serious in people who are weak or ill or who are being treated in the hospital. Sometimes staph bacteria can cause more serious widespread infection.
In the hospital, staph infections are more likely to occur in wounds, burns, or places where there is a break in the skin or where tubes enter the body. In the community, these infections are more likely to occur among people who have cuts or wounds and who have close contact with one another.
