Methicillin-Resistant Staph Infection

(MRSA; Methicillin-Resistant Staphylococcus aureus Infection; Infection, Methicillin-Resistant; Methicillin-Resistant Staphylococcus aureus Community-Acquired MRSA;CA-MRSA; Methicillin-Resistant Staphylococcus aureus Nosocomial MRSA;Healthcare-Associated MRSA;HA-MRSA)


Methicillin-resistant staphylococcus aureus (MRSA) is a potentially serious infection that resists antibiotics. MRSA can affect the skin, blood, bones, or lungs. A person can either be infected or colonized with MRSA.There are 2 types of MRSA infections:
  • Community-acquired—getting the infection outside of a healthcare setting, such as a hospital or clinic
  • Nosocomial—getting the infection while inside a healthcare setting
MRSA can spread several ways:
  • Contaminated surfaces
  • Person-to-person
  • From one area of the body to another


MRSA is caused by specific bacteria that resist antibiotics. Over time, bacteria adapt to repeated exposure to antibiotics, building up a resistance to them.
