Because hospital and community strains of MRSA generally occur in different settings, the risk factors for the two strains differ.
Risk factors for HA-MRSA
- Being hospitalized. MRSA remains a concern in hospitals, where it can attack those most vulnerable — older adults and people with weakened immune systems.
- Having an invasive medical device. Medical tubing — such as intravenous lines or urinary catheters — can provide a pathway for MRSA to travel into your body.
- Residing in a long-term care facility. MRSA is prevalent in nursing homes. Carriers of MRSA have the ability to spread it, even if they're not sick themselves.
Risk factors for CA-MRSA
Nov. 13, 2012
- Participating in contact sports. MRSA can spread easily through cuts and abrasions and skin-to-skin contact.
- Living in crowded or unsanitary conditions. Outbreaks of MRSA have occurred in military training camps, child care centers and jails.
- Men having sex with men. Homosexual men have a higher risk of developing MRSA infections.
