Who is at risk for HA-MRSA infections?

Immunocompromised patients are at heightened risk for Healthcare-Associated Methicillin-Resistant Staphylococcus aureus (HA-MRSA) infections due to their weakened immune systems. Individuals whose immune responses are compromised—due to conditions such as cancer, diabetes, HIV/AIDS, or the use of immunosuppressive medications—are less equipped to fight off infections. HA-MRSA is particularly concerning in healthcare settings where such patients are often found, as the bacteria can thrive and spread in these environments.

In contrast, individuals with a strong immune system (like those implied in the first choice) generally have an effective defense against infections, including those caused by antibiotic-resistant bacteria. Practicing good hygiene can significantly reduce the risk of many infections, including HA-MRSA, so people who maintain high standards of personal cleanliness are less likely to develop these infections. Lastly, while teenagers may have certain behaviors that could expose them to infections, they do not necessarily hold a unique risk for HA-MRSA unless they are immunocompromised or in specific environments that increase their exposure. Thus, the correct identification of immunocompromised patients as at risk highlights the importance of targeting protective measures for those most vulnerable in healthcare settings.
