MRSA

The latest development in the saga of methicillin-resistant Staphylococcus aureus, reviewed by Dr Newsom in his useful editorial (November 2004, JRSM1), is the emergence of community-acquired MRSA (CA-MRSA) in various parts of the world.24 One wonders about the future, especially when the manifestations have included severe necrotizing pneumonia in previously healthy individuals. In a study from Taiwan, carriage of MRSA was identified in a substantial proportion of schoolchildren without any apparent risk factors.5 Another report suggests, alarmingly, that CA-MRSA may have its own independent origins, distinct from hospital-originated strains.6 Despite vigorous attempts at containment, it seems that MRSA is undergoing this microbiological evolution in several parts of the world. Novel approaches will be needed, to counter these epidemiological trends.
