Methicillin-resistant Staphylococcus aureus (MRSA) Q&As
 
What is MRSA?
Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria that is resistant to certain or all types of the beta-lactam classes of antibiotics, such as penicillins, penicillinase-resistant penicillins (e.g. cloxacillin) and cephalosporins. 

What causes MRSA?
Staphylococcus aureus (S. aureus) bacteria lives on the skin, nose, the lower intestine, and may cause an infection and resist antibiotics (people may carry the bacteria without having symptoms). Risk factors for MRSA acquisition include invasive procedures, prior treatment with antibiotics, and prolonged hospital stays.

How does MRSA spread?
The spread of MRSA occurs through contact and can live on surfaces. Good hand hygiene is the single-most effective way to prevent the spread of infectious diseases like MRSA.
