Who is at the greatest risk for community-acquired MRSA infection?

Community-acquired Methicillin-resistant Staphylococcus aureus (MRSA) infections are often associated with certain high-risk groups due to their specific behaviors and living conditions that facilitate the transmission of the bacteria. Intravenous (IV) drug abusers are at greater risk because they frequently have skin punctures from needles that can become infected with MRSA. Additionally, IV drug users may have compromised skin integrity and may share needles, making them susceptible to infections in environments where MRSA is prevalent.

While children under 2 years of age, military personnel, and individuals living in shelters can also be at risk for MRSA infections, IV drug users are particularly vulnerable due to the combination of factors like exposure to unsanitary conditions and the direct introduction of bacteria into the bloodstream through injection practices. Understanding these risk factors is crucial for identifying and implementing preventative measures in communities where MRSA is a concern.
