Review of methicillin-resistant Staphylococcus aureus nasal carriage

Staphylococcus aureus is one of the commonest human pathogens capable of causing a wide range of infections, especially hospital and community associated infections. The anterior nares are the most common ecological niches, as it can be found on other non-nasal sites such as, throat, perineum, skin, hairline, groin and the axilla. A great deal of virulence from this organism occurs through cross-infection spread from patient to patient in hospitals and other institutional settings. In contrast, healthy individuals have a small risk of contracting an invasive infection caused by the organism, but they can be carriers of the organism, thereby posing as threats to susceptible individuals. This work tried to review the current trends in methicillin resistant staphylococcus aureus nasal carriage across some selected countries of the world and by extension the world as a whole.
