Facts About Mercer Disease

Mercer disease is caused by methicillin-resistant staphylococcus aureus bacteria, and is also known as MRSA (see Resources). According to the Centers for Disease Control, MRSA infections occur mostly in patients of health care facilities. CA-MRSA infections occur in people who have not been in a health care facility. These cases typically involve the skin.

  1. History

    • Penicillin was discovered in 1928 by Alexander Fleming and methicillin was later made from this base drug. The first cases of MRSA were reported by hospitals in the 1970s.

    Appearance

    • On the skin, Mercer disease looks like a pimple or boil. Other MRSA infections manifest as lung, blood or surgical site infections.

    Prevention

    • To prevent getting MRSA, wash hands often, keep cuts covered and do not share personal items. Use good hygiene to prevent infection (see Resources).

    Treatment

    • MRSA infections are treated with antibiotics either in or out of the hospital. Skin boils may be drained to cure infection.

    Prevent Spreading Infection

    • If a person has MRSA, he should cover the infected wound, keep his hands clean, do not share personal items and follow doctor's orders.
