Methicillin-resistant staphylococcus aureus (MRSA) enters the body through a cut or break in the skin, and can manifest itself as a skin infection. Symptoms include redness, areas warm to the touch, seeping blister or boil and swelling.

Officials at the Allegheny County Health Department said other types of antibiotics can be used to treat the infection. 20% to 50% of us already have some form of staph in the body but there are no signs of illness. Some people seem to be immune from infection of certain strains. But others, called "carriers" are sensitive to staph and if they come in contact with the bacteria through a break in the skin can develop an infection.

So far there have been 72 cases reported this year, 37 of them by people 18 years old or younger.  None of these cases required hospitalization.

The MRSA bacteria live in damp, warm areas. They can transferred though soiled linens, razors, soaps or washcloths, to name a few.

A properly bandaged and treated infection is not life-threatening, and most other people who come into contact with it don't develop the illness. A small percentage are susceptible to infection.

Once a person becomes infected, they could have a recurrence.

Preventive measures include frequent hand washing, no sharing of towels or equipment, showering as soon as possible after physical activity, and washing personal items (including athletic practice gear) on a daily basis. In the event of a skin lesion, the area should be completely covered to aid in healing and to prevent transmission of infection.

Information on MRSA can be obtained from the Center for Disease Control (CDC) website (www.cdc.gov).
