What are the causes of staph infections?

Staphylococcus aureus (S. aureus) bacteria is a common cause of skin infections, such as boils and abscesses. It can also cause more serious infections, such as pneumonia, bloodstream infections, and toxic shock syndrome.

S. aureus bacteria are found on the skin and in the noses of many healthy people. These people are not infected with the bacteria, but they can still spread it to others.

S. aureus infections can occur when the bacteria enter the body through a break in the skin, such as a cut or scrape. They can also occur if the bacteria are inhaled or ingested.

Some of the risk factors for S. aureus infections include:

- Weakened immune system

- Diabetes

- Kidney disease

- Intravenous drug use

- Recent surgery

- Hospitalization

S. aureus infections can be treated with antibiotics, but they can sometimes be difficult to treat. Some strains of S. aureus are resistant to antibiotics, making them more difficult to kill.
