What exacctly is a staff infection?

Not Medical Advice: As explained by WebMD, a staph infection is caused by a Staphylococcus (or "staph") bacteria. Actually, about 25% of people normally carry staph in the nose, mouth, genitals, or anal area, and don’t have symptoms of an infection. The foot is also very prone to picking up bacteria from the floor. The infection often begins with a little cut, which gets infected with bacteria. This can look like honey-yellow crusting on the skin.

These staph infections range from a simple boil to antibiotic-resistant infections to flesh-eating infections. The difference between all these is the strength of the infection, how deep it goes, how fast it spreads, and how treatable it is with antibiotics. The antibiotic-resistant infections are more common in North America, because of our overuse of antibiotics.

One type of staph infection that involves skin is called cellulitis and affects the skin's deeper layers. It is treatable with antibiotics.

This type of infection is very common in the general population and more common and more severe in people with weak immune systems. People who have diabetes or weakened immunity are particularly prone to developing cellulitis.
