How do i spread a staph infection on my butt?

Hand Contact: Most staph. Infections are spread from person-to-person by hand contact. These infections start by introducing the germ to a new site; if the skin is intact, then no infection developes and the person may just harbor the organisim. Any break in the skin may introduce the germ into the deeper layers of the skin, thereby setting up the potential for a serious infection. Frequent handwashing helps.
