Facts on MRSA Disease

Overview

MRSA is the abbreviation for Methicillin-Resistant Staphylococcus aureus, a bacterial infection that is resistant to some types of antibiotics. MRSA does not respond to antibiotics called beta-lactam drugs. These are medications that are commonly prescribed for bacterial infections, and include amoxicillin and penicillin. If MRSA is not treated, the infection can spread to the bones or bloodstream and become life-threatening in some cases, according to the Mecklenburg County, North Carolina Health Department.

Causes

MRSA is caused by the staphlococcus aures bacteria. All people have bacteria on their skin and inside their noses, but the bacteria that causes MRSA is not as common. MRSA infections are spread through close personal contact.

Risk Factor

People who have immunodeficiencies such as the HIV virus, may be more prone to developing MRSA infections. People who live or work in large community settings, such as a school or a hospital may be more likely to develop infection, due to being in close contact with a large germ pool. Athletes also carry a higher risk.

Symptoms

Symptoms include a reddening of the skin, an infected area that may at first look like a pimple, or an infection that oozes pus. Some people with MRSA infections feel pain or experience swelling in the affected area of the body.

Diagnosis

MRSA infections (sometimes called MRSA disease) are diagnosed by taking a biopsy of the infected skin. Lab technicians will use the biopsied material to determine which specific medication will be an effective treatment.

Treatment

Treatment includes a regimen of non-resistant antibiotics. Infections may be drained as well to promote healing.

Prevention

Frequent hand washing can help prevent MRSA infections. Cleaning and covering open wounds prevents bacteria from entering the body. Athletes can prevent infection by making sure all uniforms and equipment are kept clean and sanitized with alcohol or antibacterial wipes.
