Varicella infection and the impact of late entry into the Irish healthcare system.

We present a case which highlights several areas of concern relating to the prevention and management of varicella in Ireland. We review the pathophysiology of this virus and highlight its greater potential for morbidity in certain groups, most particularly adult males. The experience and opinions with regard to varicella vaccination in the US and other temperate countries is reviewed along with evidence of changing epidemiology of varicella infection. The National Immunisation Advisory Committee (NIAC) guidelines are reviewed in the context of our experience.
