Methicillin-resistant Staphylococcus aureus, or MRSA, a drug-resistant bacteria that is sometimes fatal, was once only seen in healthcare settings, but it has spread to schools and gyms.

To guard against MRSA and other germs, the APIC recommends:

-- Practice proper hand hygiene, washing hands for at least 15 seconds and using hand sanitizer containing a minimum of 60 percent of alcohol the right way -- rub until hands are dry.

-- Not share towels, razors, equipment and sports gear. Heavily trafficked environments like gyms or classrooms are potential bacteria breeding grounds -- keep wounds covered and clean, avoid touching wounds of others and shower after sports activities.

-- Superbugs are a man-made problem, thanks in large part to the improper use of antibiotics -- don't press a doctor to prescribe unnecessary antibiotics.

-- In a healthcare setting, wash your hands after touching surfaces like bed rails and IV poles.

-- Demand proper hand hygiene from healthcare providers -- request they use hand sanitizer before and after you are treated.

-- Wash hands before and after visiting someone in a healthcare setting. Anyone entering a hospital can unintentionally bring in, or take a bug home.
