Staphylococcus aureus, commonly called “staph,” is a type of bacteria found on the skin or in the nose. About 30% of people have staph bacteria, but do not have any symptoms of an infection. MRSA (Methicillin-Resistant Staphylococcus aureus) is a staph that is resistant to commonly used antibiotics. Skin infections with MRSA often begin with an injury allowing the bacteria to enter the skin and develop into an infection.
MRSA is most commonly found in health care facilities but is a rapidly emerging public health problem in the larger community, often among athletes of close-contact sports such as wrestling, football and rugby. Community-associated MRSA has become the most frequent cause of skin and soft tissue infections presenting to emergency departments in the US.
In the community, most MRSA infections are skin infections that may appear as red, swollen, painful pustules or boils, and which may have pus or other drainage. These infections commonly occur at sites of visible skin trauma, such as cuts and abrasions, and in areas of the body covered by hair (back of neck, groin, buttocks, armpits, beard area).
Staph infections, including MRSA, generally start as small red bumps that resemble pimples, boils or spider bites. These can quickly turn into deep, painful abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin. But they can also burrow into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.
MRSA is transmitted through direct skin-to-skin contact with an infected person or through contact with items or surfaces that have come into contact with someone else’s infection (e.g., towels, sheets, sports equipment, bandages, razors). Breaks in the skin such as cuts or abrasions can allow MRSA to enter the body and cause infection. Unsanitary living conditions or participation in contact sports can increase the risk of MRSA transmission.
Keep an eye on minor skin problems—pimples, insect bites, cuts and scrapes. If you are a Brown student and think you have an infection, contact Health Services at 401.863-3953 for an appointment as soon as possible. Early treatment can help prevent the infection from becoming more serious.
Doctors diagnose MRSA by checking a tissue sample or nasal secretions for signs of the drug-resistant bacteria.
MRSA may be treated with antibiotics, particularly vancomycin, that have proved effective against particular strains. To help reduce the threat that MRSA will become resistant to these antibiotics, doctors may drain an abscess caused by MRSA rather than treating the infection with drugs.
MRSA might spread more easily among athletes because they may:
- Tend to have repeated skin-to-skin contact.
- Share items and surfaces that come into direct skin contact.
- Have difficulty staying clean during training or games.
- Get cuts or abrasions in the skin that, if left uncovered, allow staph and MRSA to enter and cause infection.
These common-sense precautions can help you reduce your risk and help prevent the spread of MRSA:
- Wash your hands. Careful hand washing is your best defense against germs. Scrub hands briskly for at least 15 seconds, then dry them with a disposable towel and use another towel to turn off the faucet. Carry a small bottle of hand sanitizer.
- Avoid sharing personal items such as towels, sheets, razors, clothing and athletic equipment. MRSA can be spread through contaminated objects as well as through direct contact.
- Wash towels and sheets frequently in hot water. Do not overload washing machine.
- Keep wounds covered. Cuts and abrasions should be kept clean and covered with sterile, dry bandages until they heal. The pus from infected sores may contain MRSA, and keeping wounds covered will help keep the bacteria from spreading.
- Shower immediately after athletic games or practices. Use soap and water. Don’t share towels.
- Ask your coach or athletic trainer whether you should sit out games or practices if you have a wound that’s draining or appears infected (red, swollen, warm to the touch or tender).
- If you have a cut or sore, wash towels and bed linens in a washing machine set to the “hot” water setting (with added blea ch if possible) and dry them in a hot dryer. Wash gym and athletic clothes after each wearing.
- If you have a skin infection that requires medical treatment, ask if you should be tested for MRSA. Testing for MRSA may get you the specific antibiotic you need to effectively treat your infection.
- Always use antibiotics appropriately. When you’re prescribed an antibiotic, take all of your doses, even if the infection is getting better. Don’t share antibiotics with others or save unfinished antibiotics for another time. Inappropriate use of antibiotics, including not taking all of your prescription and overuse, contributes to resistance. If your infection isn’t improving after a few days of taking an antibiotic, contact your medical provider.
