Which of the following does NOT increase the risk of developing community-acquired MRSA?

1. Frequent antibiotic use

2. Close contact with individuals in crowded settings

3. Having a high white blood cell count

4. Having open wounds or cuts

The correct answer is: Having a high white blood cell count

Having a high white blood cell count does not increase the risk of developing community-acquired MRSA. Typically, a high white blood cell count is indicative of an active immune response, often signaling that the body is fighting an infection or inflammation. In contrast, the other options listed, such as frequent antibiotic use, close contact in crowded settings, and having open wounds or cuts, are associated with an increased susceptibility to MRSA infections. Frequent antibiotic use can disrupt the natural balance of bacteria on the skin and lead to antibiotic resistance. Close contact in crowded environments, like schools or sports facilities, facilitates the spread of staph bacteria, while open wounds provide a direct entry point for infections.
