The Causes, Symptoms, and Treatment for MRSA

News stories of the superbug MRSA, or Methicillin-Resistant Staphylococcus Aureus, are almost as rampant as the strain of drug-resistant staph bacterial infection itself. With new stories emerging almost daily concerning the MRSA cropping up in elementary schools and athletic locker rooms, it’s not wonder this new “super bug” is on everyone’s mind.

Let’s examine the causes, symptoms, treatment, risk factors, and prevention for MRSA…

1. What is MRSA?

Methicillin-Resistant Staphylococcus Aureus (or MRSA) is strain of staphylococcus aureus (or staph) bacterium that infects various parts of the body with sores, boils, or mild skin infections. Typically, we all carry staph bacteria on our bodies (and inside our noses) without threat of infection.

However, staph bacterium is dangerous if it enters the body via wound or cut and causes an infection.  A primary cause of skin infections among Americans, staph infections are usually minor. But severe forms of staph infection, like MRSA, result with the infection of surgical wounds, organs (i.e., lungs causing pneumonia), and bloodstream of those with weakened immunity.
