"The most common cause of staph infections, S. aureus is a bacteria found on the skin or in the nose of about 25-30 percent of people. It also can be the culprit in minor skin infections like pimples and boils, as well as major diseases like meningitis, endocarditis, toxic shock syndrome and pneumonia."
I had this - staph aureus. It's AWFUL. I had to be on bactrum. It got rid of it. I had cold chills and dizziness.
I have transported patients with MRSA and never got it. I wore gloves and washed my hands after. I cleaned the ambulance with care. I wasn't worried about getting it, and I didn't. Luck of the draw?
