“…Varicella zoster virus (VZV) causes both varicella (chickenpox) following primary infection and herpes zoster (HZ, shingles) associated with reactivation of latent VZV. Both illnesses are important causes of morbidity in Australia and represent a significant cost to the community [1][2][3][4][5][6]. A live attenuated varicella vaccine was introduced into the routine immunization schedule in the USA in 1995 and resulted in significant reductions in varicella incidence, hospitalizations, mortality, and associated healthcare costs [7][8][9][10][11].…”

Herpes zoster in Australia: evidence of increase in incidence in adults attributable to varicella immunization?

Rates of herpes zoster (HZ) hospitalizations, antiviral prescriptions, and New South Wales emergency-department presentations for age groups <20, 20-39, 40-59 and ⩾60 years were investigated. Trends were analysed using Poisson regression to determine if rates increased following funding of varicella immunization in Australia in November 2005. The regression analysis revealed significantly increasing trends of between 2% and 6% per year in both antiviral prescriptions and emergency-department presentations in all except the <20 years age group. When considered together, the differential changes in rates observed by age group provides preliminary evidence to indicate that HZ incidence is increasing in adults aged >20 years. However, it is not possible to attribute the increasing trends in HZ observed directly to the varicella immunization programme, and continued monitoring and analyses of data for a longer duration, both pre- and post-vaccine introduction, is required.

“…Reduction in wild chickenpox may cause a decrease in herd immunity necessitating booster vaccination, therefore possibly affecting any cost–benefit analysis in children. Vally et al however predict that routine vaccination in Australia should result in a decrease in direct and indirect costs as a result of chickenpox, provided high coverage rates can be achieved 16. The impact of routine varicella vaccination in childhood on herpes zoster epidemiology is an area where considerable debate exists.…”

We report the first reported cases of epidemiologically linked invasive group A streptococcal septicaemia, with one fatality, following primary chickenpox infection in previously fit and well children who attended the same preschool. Invasive group A streptococcal sepsis is a well documented complication of chickenpox, which requires prompt and aggressive treatment. Following the cluster, public health measures were put in place to prevent further disease. Varicella vaccination has been shown to significantly reduce hospital admissions as well as deaths related to chickenpox infection. This is the first reported cluster of two epidemiologically linked patients in the UK.
