Serious infections due to methicillin-resistant Staphylococcus aureus: An evolving challenge for physicians

Abstract 

Methicillin-resistant Staphylococcus aureus (MRSA) is a well-recognized major cause of nosocomial infection worldwide. During the past decade, however, the epidemiology of staphylococcal infections has partially changed, with an increase in the number of patients who acquire infections in the community. The changing epidemiology is a cause for concern among physicians, leading to an increase in the number of patients with infections due to MRSA diagnosed at hospital admission and in the emergency department. The aims of this article are to review the current state of knowledge regarding MRSA infections, to identify those factors which may help physicians to recognize the patients at high risk, and to manage these infections appropriately.
