Can i pick up a staph infection at home or work?

Not easy: Unless you have an immune deficiency of some kind the chance of getting a staph infection is very low, staph grows normally on the skin but rarely invades the skin or other parts of the body.

More likely w/ MRSA: Staph is all over. There is usually an intrinsic or extrinsic inciting event. If the innate immune system is healthy it usually wards staph off. But if there is a breach in the skin barrier, a staph infection may ensue, but walled off quickly by the immune system. If its a more virulent form of staff such as community acquired mrsa, the chance of an "staph infection" such as an abscess is higher.
