To the Editor: The article by Nelson and colleagues1 is a welcome contribution to understanding trends in varicella zoster virus (VZV) disease epidemiology in Australia, particularly ambulatory medical attendance, for which few data sources are available. They report a decline in general practitioner encounters for varicella (chicken pox) since the introduction of varicella vaccine that is consistent with the observed 69% reduction in national hospitalisation rates in children aged 1.5 to 4 years seen from January 2006 to June 2008, 2.5 years into the National Immunisation Program (NIP).2
