MRSA infection is caused by a staph bacteria that is resistant to many of the antibiotics doctors use to treat other staph infections, explains Mayo Clinic. There are two types of MRSA: health care-associated MRSA and community-associated MRSA.

Risk factors for health care-associated MRSA include hospitalization, living in a long-term care facility and having an invasive medical device. Additionally, the use of medical tubing such as catheters or intravenous lines increases risk by allowing a path for MRSA to enter into the body.

Risk factors for community-associated MRSA include participating in contact sports such as wrestling, living in unsanitary or crowded conditions, and engaging in homosexual sex, notes Mayo Clinic. MRSA spreads easily through skin-to-skin contact.

Although MRSA infections resist the effects of many antibiotics and are very difficult to treat, both types of MRSA do respond to certain antibiotics, states Mayo Clinic.
