How can you get rid of a staph infection?

Depends on where. Antibiotics are usually needed to get rid of staph infections, which are usually pus-forming. There are different kinds of staph bacteria, with some being more resistant to antibiotics (such as MRSA strains) than others, and with some being more dangerous than others. The location and the background health of the patient also determines the kind of antibiotic treatment, so a doctor is needed.
