What is Methicillin-Resistant Staphylococcus Aureus (MRSA)?*
Methicillin-resistant Staphylococcus aureus (MRSA) is a serious bacterial skin infection that can be spread through close skin-to-skin contact, inadequate hygiene, openings in the skin, crowded living conditions, and contaminated objects. There are typically two settings in which people can become infected.
MRSA infections that are acquired by otherwise healthy people who have not been hospitalized or who have not undergone a medical procedure within the past year are characterized as community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA). These infections usually appear as pimple or boil that can be red, swollen and painful. Health care-associated MRSA (HA-MRSA), which accounts for the vast majority of MRSA infections, is acquired by patients with compromised immune systems in hospitals or other health care settings, and could include surgical wound infections, urinary tract infections, bloodstream infections, and pneumonia.
