Sensational news stories of late suggest that drug-resistant staph (MRSA, for methicillin-resistant staphylococcus aureus) is spreading only among men who have sex with men. But sexual orientation has nothing to do with MRSA danger. The really sensational news? You can now quickly identify whether an infection is plain old staph or the resistant kind.

A newly approved lab test can determine what kind of staph infection you have in just two hours; the older method took two days. This allows docs to prescribe the right kind of antibiotics immediately, minimizing recovery time.
