Have you ever had a wound or a boil somewhere on your body that hasn't healed in days? Sometimes we think, "Oh, it's just a small boil." But some wounds and infections don't heal even with regular antibiotics. In those cases, the cause may be a "superbug" that is a little more dangerous than a normal bacterium and doesn't easily get caught by drugs. Today we're going to talk about one such bacterium that has caused us a lot of concern in the medical world. That's MRSA.
Simply put, what is MRSA?
The name MRSA may sound a bit complicated. Its full name is Methicillin-resistant Staphylococcus aureus . Let's keep it simple.
- Staphylococcus aureus: This is a very common type of bacteria that lives harmlessly on our skin, inside our noses, and in other places. We call it "Staph" bacteria for short. Usually, if this bacteria enters our body, it can enter through a small wound or cut and cause a small abscess or abscess. However, these can be easily cured with commonly prescribed antibiotics.
- Methicillin-resistant: Here's the problem. `Methicillin` is a very commonly used antibiotic that belongs to the `Penicillin` family. "Resistant" means 'resistant.' That is, this particular strain of Staph bacteria called MRSA has developed the ability to resist many antibiotics, including `Methicillin.`
Simply put, MRSA is a type of Staph bacteria that has the ability to "fight and win" against common antibiotics. It's like fighting an enemy and building special armor to protect yourself from their weapons. This makes it very difficult to treat an MRSA infection, as there are very few drugs that work against it.
MRSA is a special member of the Staph bacteria family that has developed a superpower of resistance to antibiotics.
There are two main types of MRSA infections:
MRSA infections are divided into two main types based on how they can be transmitted to us. This is very important to understand.
1. Healthcare-Acquired MRSA (HA-MRSA): As the name suggests, this type is spread in healthcare settings such as hospitals, clinics, and nursing homes. People who have been hospitalized for a long time, have had surgery, or have had an intravenous line inserted into their body are at higher risk of contracting this type. Because antibiotics are often used in hospitals, bacteria there are more likely to develop resistance to them.
2. Community-Acquired MRSA (CA-MRSA): This is the type we should be most concerned about. It is not spread from a hospital, but from our general society. It can be spread in crowded places like schools, sports venues (gyms, playgrounds), military bases, boarding schools. Even a normally healthy person can get it.
What are the symptoms of a MRSA infection?
The symptoms of an MRSA infection depend on where in the body it has affected. Sometimes these may seem like a normal infection, but they can quickly become serious.
| Site of infection | Symptoms you may see |
|---|---|
| Skin and soft tissue infections | This is the most common type. Sometimes it starts as a red, swollen, painful bump , like a spider bite . It gradually enlarges and becomes an abscess filled with pus. The surrounding skin may become red and feel hot to the touch. |
| Lung infection (Pneumonia) | Severe cough, difficulty breathing, chest pain, high fever, and fatigue. |
| Spread of infection into the blood (Bacteremia) | This is a very serious condition. As the bacteria enter the bloodstream, symptoms such as high fever, chills, rapid heartbeat, and low blood pressure can occur. |
| Bone and joint infections (Osteomyelitis) | The infected bone or joint will experience severe pain, swelling, and redness, making it difficult to move the affected area. |
| Heart infection (Endocarditis) | Bacterial infection of the inner lining of the heart. May cause fever, weakness, difficulty breathing, and abnormal heart sounds (murmurs). |
How is MRSA transmitted?
MRSA is a contagious disease. This means that it can spread from one person to another. Some people have MRSA bacteria in their bodies (for example, inside their noses) but do not show any symptoms. We call them "colonized carriers." Even if they do not have any symptoms, they can still spread the bacteria to others.
Here are some of the main ways MRSA is transmitted:
- Direct contact: By touching a wound or skin of someone who has an infection.
- Touching contaminated surfaces: MRSA bacteria can live on surfaces like doorknobs, tables, and bed sheets for weeks. You can get infected if you touch such a surface and then touch your nose or mouth with the same hand.
- Sharing personal items: Sharing items like towels, razors, clothes, and sports equipment with an infected person can easily spread the infection. Imagine a rugby team sharing towels, and if one person has it, there is a high chance that the others will also be infected.
- Contaminated medical equipment: Infection can occur through improperly sterilized equipment or implanted devices (e.g., central venous line, breathing tube) in hospitals.
Who is at higher risk of developing MRSA?
Although anyone can get MRSA, some people are at a higher risk.
| Risk group | Reason |
|---|---|
| People receiving treatment in hospital | People who have been in the hospital for a long time, those who have undergone surgery, and those who have devices such as tubes inserted into their bodies are especially at risk. |
| People with weak immunity | People with medical conditions such as diabetes, kidney disease, HIV, or cancer can easily become infected due to weakened immune systems. |
| People who hang out in groups | The risk is higher in places like military barracks, dormitories, and prisons because people live in close proximity to each other and there is a greater chance of sharing personal items. |
| People who engage in contact sports | In sports such as rugby and wrestling, the risk of infection is high due to skin-to-skin contact, abrasions, and sharing of equipment. |
| People who inject illegal drugs | There is a high risk of blood-borne infection due to repeated use or sharing of the same injection needles. |
How do doctors diagnose and treat an MRSA infection?
If you suspect you have an MRSA infection, a doctor will take a sample from the infected area and send it to a lab for testing. This could be a sample of pus from a wound, a blood sample, a urine sample, or a phlegm sample.
The laboratory will grow the bacteria in this sample and examine it for ``Culture.'' Then, they will find out which antibiotics work on that bacteria and which do not work (Antibiotic Susceptibility Test). Only after this test is it confirmed that it is MRSA and the most appropriate medicine is chosen.
Treatment methods
MRSA treatment depends on the type and severity of the infection.
- For skin infections: Most often, if there is a pus-filled abscess, it is cut open and the pus is removed (Incision and Drainage). Sometimes this alone can control the infection. In addition, you may need to use antibiotic pills or ointments prescribed by your doctor.
- For severe infections: If the infection has spread to the bloodstream, lungs, or other internal organs, you may need to be hospitalized and given intravenous (IV) antibiotics . These are very strong medications. Sometimes more than one type of antibiotic may need to be given at the same time.
The most important thing is to never stop taking your prescribed course of antibiotics for any reason . If you stop taking the medication just because you feel better, the remaining bad bacteria can grow back and become resistant to the medication.
What should we do to stay safe from MRSA?
Although MRSA is a dangerous infection, we can do a lot to protect ourselves from it by maintaining good personal hygiene.
- Wash your hands often: This is the most important thing. Wash your hands thoroughly with soap and water for at least 20 seconds . Be sure to wash your hands after going out, before eating, and after using the bathroom. Use an alcohol-based hand sanitizer when water is not available.
- Keep wounds covered: Always keep any scrapes or cuts on your body clean and cover them with a clean bandage. Always wash your hands after touching a wound.
- Don't share personal items: Don't share things like towels, razors, clothes, and bars of soap with others. Be especially careful about this at the gym and in dormitories.
- Clean surfaces: Clean frequently touched surfaces, such as doorknobs, light switches, telephones, and sports equipment, with a disinfectant solution.
- Shower after exercise: Shower as soon as possible after working out at the gym or playing sports.
When to see a doctor? When to go to the ETU?
Not all skin lesions are MRSA, but there are some symptoms that we should be especially concerned about.
If you have a wound or boil that won't heal, especially if you have a disease that lowers your immune system, like diabetes, don't ignore it. Be sure to see your doctor.
Go to the Emergency Department (ETU) immediately if you have the following symptoms:
- High fever: If the fever is higher than 103°F (40°C).
- The wound is severe: If the wound is causing severe pain, has a foul odor, or is draining green, yellow, or brown fluid.
- Difficulty breathing and chest pain.
- Sudden drop in blood pressure: If you feel faint, dizzy, or faint.
- Confusion: If you feel dizzy.
These could be signs that the infection has spread throughout the body and is progressing to a very dangerous condition called sepsis . Therefore, it is not a good idea to delay at a time like this.
