BACKGROUND There are limited population-based data regarding pediatric herpes zoster (HZ). METHODS Children aged <12 years with varicella infections between 2000 and 2006 were identified from a national population-based database and followed-up for a diagnosis of HZ until December 2008. Since a routine varicella vaccination program was started in 2004, vaccinated children without medically at...

Background: Varicella zoster virus (VZV) infection is one of the nosocomial infections and healthcare workers (HCWs) are at high risk group who work in the hospital with likelihood of varicella acquisition or transmission. This study evaluated the VZV seroprevalence in this high risk population in Babol, Iran. Methods: Serological testing for VZV using enzyme linked immunosorbent assay (ELISA)...

The aim of this study was to examine the most cost-effective strategy screening and vaccinating measles- varicella-susceptible health care workers (HCWs). A retrospective cost-effectiveness analysis conducted at a tertiary hospital in Korea with 300 HCWs who were high risk infection. Self-reported histories vaccinations, infectious diseases, contact such cases collected. Serological tests for i...

The recent introduction of a vaccine for varicella has raised questions about whether, for adults, a patient's history of varicella infection is useful in determining if vaccination is necessary. We report findings on 184 family medicine patients aged 18 to 65 years who were asked if they had a history of varicella infection and were subsequently tested for varicella antibodies. A history of in...

Serological evidence for hepatic cellular injury may occur during uncomplicated varicella. The magnitude of abnormalities may be helpful as a guide in the management of children with progressive varicella or varicella-associated Reye's syndrome, but liver function tests may be in the normal range. Viraemia was not detected during the acute stage of varicella-associated Reye's syndrome.

BACKGROUND Varicella zoster virus (VZV) causes varicella and, later in the life of the host, may reactivate to cause herpes zoster (HZ). Because it is hypothesized that exposure to varicella may boost immunity to latent VZV, the vaccination-associated decrease in varicella disease has led some to suggest that the incidence of HZ might increase. We assessed the impact that varicella vaccination ...

A quadrivalent vaccine combining measles, mumps, rubella, and varicella antigens (MMRV) was developed to increase the coverage of varicella vaccine and reduce the number of injections children receive. Although the varicella antigen is as immunogenic in the latest formulation of MMRV vaccine as when it is administered alone, up to 14% of vaccine recipients do not achieve protective levels of an...

INTRODUCTION Varicella (chickenpox) can cause serious complications and admission to hospital. Several countries included the varicella vaccine in their immunization schedules. MATERIAL AND METHODS A descriptive and retrospective study of hospitalizations due to varicella and its complications was conducted in a referral center from 2005 to 2011. RESULTS A total of 1192 children with varice...

BACKGROUND/AIMS The transmission rate of air-borne infectious diseases may vary secondary to climate conditions. The study assessed time trends in the seasonality of hospitalized varicella cases in a temperate region in relation to climatic parameters prior to the implementation of universal varicella immunization. METHODS A retrospective descriptive study was conducted among all pediatric an...

complication of infection with maternal varicella before 20 weeks of pregnancy. Prospective studies in Europe and North America have shown that the incidence of congenital varicella syndrome in maternal varicella contracted in the first 20 weeks of pregnancy is about 1%–2%. Based on this estimated risk (1%), on an estimated risk of varicella infection during pregnancy of two maternal infections...
