Staph infection result from nasal swab what is it?

Nothing special: The presence of staph on a nasal swab means only that you are carrying a strain in the lush mucoid environment where it can thrive. It doesn't do well on the dry skin surface for long periods of time. With it in your nose you could spread it to bug bits by scratching with contaminated fingers, or to door handles or other objects. Since most have no symptoms, nasal carriage allows it to spread.
