Methicillin-resistant staphylococcus aureus, also known as super bug MRSA, is a type of staph infection that is resistant to commonly used antibiotics, such as penicillin, oxacillin and amoxicillin. Staph infections are one of the top causes of skin infections in the United States, as stated by WebMD.
MRSA is spread from contact, exposure to the bacterium. People in nursing homes, medical centers and those with weak immune systems are at a higher risk of contracting MRSA than others, according to WebMD. There are two classifications of MRSA: health-care associated MRSA and community-associated MRSA, notes Medical News Today. Those at higher risk for contracting health-care associated MRSA include individuals who have open cuts or burns on the skin, and people who frequently take antibiotics. Community-associated MRSA is more common in people living in highly populated, unhygienic environments.
Symptoms of a MRSA infection include bumps on the body that look similar to spider bites or acne. The bumps and the surrounding areas may feel warm or be full of pus. People with a MRSA infection also develop a fever, according to Mayo Clinic. Other possible symptoms of MRSA include abscesses, bone and joint infections, and infections of the lungs and heart valves.
