You’ve probably heard about recent “super bug,” or MRSA, skin infections affecting young people. So what is MRSA and how can you protect yourself?
MRSA stands for methicillin-resistant Staphylococcus aureus. Staphylococcus aureus is a type of bacteria with lots of different strains.
Many strains of staph bacteria are quite common. Most people have staph bacteria living on their skin or in their noses without causing any problems. If staph bacteria get into a person’s body through a cut, scrape or rash, they can cause minor skin infections. Most of these heal on their own if a person keeps the wound clean and bandaged. Sometimes doctors prescribe antibiotics to treat more stubborn staph infections.
What makes the MRSA different from other staph infections is that it has built up an immunity to the antibiotics doctors usually use to treat staph infections. (Methicillin is a type of antibiotic, which is why the strain is called “methicillin-resistant.”)
MRSA is making headlines, but it’s not a new infection. The first case was reported in 1968. In the past, MRSA usually affected people with weakened immune systems, such as those living in long-term care facilities like nursing homes.
But now some otherwise healthy people who are not considered at risk for MRSA are getting the infection. Doctors call this type of infection community-associated MRSA (CA-MRSA) because it affects people who spend time together in groups, such as schools, college dorms or military barracks.
When lots of people come together and are likely to touch the same surfaces, have skin-to-skin contact, or share equipment that has not been cleaned, an infection can spread faster than it would otherwise. That’s why recent MRSA infections involved athletes in gyms and locker rooms. If the MRSA bacteria get onto a kneepad, for example, and someone with a skinned knee wears the pad without cleaning it, that person’s risk of infection is higher.
HOW TO PROTECT YOURSELFMRSA may sound scary because it is resistant to some antibiotics. But it’s actually easy to prevent MRSA from spreading by practicing simple cleanliness.Protect yourself by taking these steps:
- Wash your hands often using plain soap and water for at least 15 seconds each time. You might also want to carry alcohol-based instant hand sanitizers or wipes in your bag for times when you can’t wash your hands.
- If you have a cut or broken skin, keep it clean and covered with a bandage.
- Don’t share razors, towels, uniforms, or other items that come into contact with bare skin.
- Clean shared sports equipment with antiseptic solution before each use or use a barrier (clothing or a towel) between your skin and the equipment.
Even in the rare event that someone on campus becomes infected with MRSA, you can protect yourself by washing your hands, wiping any surfaces before they come into contact with your skin, and keeping any cuts covered.
HOW IS MRSA TREATED?MRSA infections can require different medications and approaches to treatment than other staph infections. For example, if a person has a skin abscess caused by MRSA, the doctor is more likely to have to drain the pus from the abscess in order to clear the infection.
In addition to draining the area, doctors may prescribe antibiotics for some people with MRSA infections. In a few cases, MRSA can spread throughout the body and cause problems like blood and joint infections – although complications like these are very rare in healthy people.
People with infections can also help prevent future bacteria from becoming resistant to antibiotics by taking the antibiotics that have been prescribed for them in the full amount until the prescription is finished (unless a doctor tells them it’s OK to stop early). Germs that are allowed to hang around after incomplete treatment of an infection are more likely to become resistant to antibiotics.
WHEN TO SEE A DOCTORCall the doctor or go to your student health center if:
- You have an area of skin that is red, painful, swollen and/or filled with pus.
- l You have an area of swollen, painful skin and also feel feverish or sick.
- l Skin infections seem to be passing among your family members (or among your roommates, fellow dorm dwellers, or students in your classes) or if two or more of them have skin infections at the same time.
Serious cases of MRSA are still rare. By taking these easy prevention steps, you can help keep it that way! For more answers and advice from the health experts of Nemours, visit MyStudentHealthZone.com.
