MRSA, or methicillin-resistant Staphylococcus aureus, is a type of bacteria that can cause infections in various parts of the body. Unlike most strains of staph, MRSA is resistant to commonly used antibiotics, making it more challenging to treat. While many MRSA infections are not serious, some can be life-threatening.
The symptoms of MRSA depend on the location of the infection. The most common signs of a MRSA skin infection include:
Swelling
Redness
Pain
Pus-filled abscesses
Yellow crusting
If MRSA infects the lungs and causes pneumonia, symptoms may include:
Shortness of breath
Fever
Chills
In rare cases, MRSA can lead to more severe infections, such as abscesses in the spleen, kidney, or spine, endocarditis (heart valve infections), osteomyelitis (bone infections), and joint infections.
Staph bacteria are common and can live on the skin or in the nose without causing harm. However, when staph enters the body through a cut or wound, it can cause an infection. Over time, some strains of staph, like MRSA, have become resistant to antibiotics that once effectively treated them.
MRSA is spread through contact with an infected person or by touching contaminated surfaces. People with weakened immune systems, such as those in hospitals or nursing homes, are at a higher risk of developing MRSA infections.
Treatment for MRSA depends on the severity and location of the infection. For minor skin infections, your doctor may prescribe oral antibiotics or recommend draining the abscess. More severe infections may require intravenous antibiotics and hospitalization.
To prevent the spread of MRSA, practice good hygiene, such as washing your hands regularly, covering wounds, and avoiding sharing personal items like towels or razors.
If you suspect you have a MRSA infection, contact your healthcare provider immediately. Signs that you should seek medical attention include:
A spreading, painful, red rash or abscess
No improvement after 3-4 days of antibiotic treatment
Worsening fever
A weakened immune system
By understanding the symptoms, causes, and treatment options for MRSA, you can take steps to protect yourself and others from this potentially serious infection. If you have concerns about MRSA, consult your healthcare provider for personalized advice and treatment.
