The prevalence of methicillin-resistant Staplrylococcus aureus (MRSA)
varies in different European countries, in different cities in the sam
e country or even within a city or a hospital. It is thought that the
overall incidence of MRSA is higher than ever before, although the rea
sons for this are unclear. MRSA typing can identify epidemic MRSA in m
any countries. The spread of a closely related clone in Northern Europ
e is a cause for concern, as it is resistant to many agents. In the UK
, control measures are threatened by changing patterns of health care
and patient demography. Resistance to mupirocin, a valuable agent in t
he control of MRSA, has emerged in many hospitals in the UK, thus the
agent must be used judiciously.
