She holds appointments at Lenox Hill Hospital and Mount Sinai Medical Center. Hospital-acquired methicillin-resistant Staphylococcus aureus, also known as healthcare-acquired MRSA or HA-MRSA, is a potentially deadly strain of staph bacteria.
Causes
When it occurs in these settings, it's known as health care-associated MRSA (HA-MRSA). HA-MRSA infections usually are associated with invasive procedures or devices, such as surgeries, intravenous tubing or artificial joints.
Prevention
Oral antibiotic options for treating skin and soft-tissue infections in patients with community-associated MRSA include clindamycin, trimethoprim/sulfamethoxazole (TMP/SMX; Bactrim, Septra), a tetracycline (doxycycline or minocycline [Minocin]), and linezolid (Zyvox).
Complications
However, MRSA infection can be serious, so seek medical care. If you are already being treated for an infection, watch for signs that your medicine isn't working. If you are taking an antibiotic, call your health care provider if: The infection is no better after three or four days of antibiotic therapy. The rash spreads.

For years, antibiotics have been prescribed for colds, flu and other viral infections that don't respond to these drugs. Even when antibiotics are used appropriately , they contribute to the rise of drug-resistant bacteria because they don't destroy every germ they target. Bacteria live on an evolutionary fast track, so germs that survive treatment with one antibiotic soon learn to resist others.

Why is MRSA so hard to treat?
Each time the bacteria causes an outbreak, it has the potential to produce mutations that promote its survival. This means that the bacteria become more infectious and more difficult to treat.

- Different varieties of Staphylococcus aureus bacteria, commonly called "staph," exist. Staph bacteria are normally found on the skin or in the nose of about one-third of the population. The bacteria are generally harmless unless they enter the body through a cut or other wound, and even then they usually cause only minor skin problems in healthy people. According to the Centers fo…
