BACKGROUND Although live-attenuated varicella-zoster virus (VZV) vaccines have been proven to be safe and effective in preventing varicella and real-word evidence shows routine childhood immunization programs are effective in dramatically reducing varicella associated morbidity and mortality, varicella vaccine is not included in the National Immunization Program (NIP) in Hungary. The purpose of...
With continuing occurrence of varicella despite increasing vaccine coverage for the past 20 years, a case-based study, a case-control study, and an immunogenicity and safety study were conducted to address the impact of varicella vaccination in South Korea. Varicella patients under the age of 16 years were enrolled for the case-based study. For the case-control study, varicella patients between...
BACKGROUND In the Netherlands, incidence of physician's consultations and hospitalizations for varicella is low compared to other countries. Better knowledge about the severity of varicella among Dutch hospitalized patients is needed. Therefore, a medical record research was conducted among hospitalized patients with diagnosis varicella. METHODS Hospital admissions due to varicella in 2003-20...
A healthy 22-year-old man developed acute varicella pericarditis, characterised by an enanthem with diagnostic rising titres of varicella zoster antibodies but without the typical exanthem. This, the third reported case of varicella pericarditis, is the first to be documented without a typical varicella eruption.
To determine vaccine effectiveness (VE), a varicella outbreak in a highly vaccinated day-care center (DCC) population in Pennsylvania was investigated. In Pennsylvania, proof of immunity is required for children >or=12 months old for DCC enrollment. Questionnaires were administered to parents of children who had attended the DCC continuously during the study period (1 November 1999-9 April 2000...
National varicella immunization coverage using the current 1-dose immunization strategy has increased among vaccine-eligible children 19 through 35 months of age from 27% in 1997 to 88% by 2005. These high immunization rates have resulted in a 71% to 84% decrease in the reported number of varicella cases, an 88% decrease in varicella-related hospitalizations, a 59% decrease in varicellarelated ...
Background and Purpose—The purpose of this study was to determine whether infection with varicella is causal for arterial ischemic stroke (AIS) in children. Methods—First, a prospective cohort study was conducted in young children (aged 6 months to 10 years) with AIS at 2 institutions (cohort study). The presence of varicella infection ,12 months before AIS was determined and compared with the ...
OBJECTIVE Routine varicella zoster vaccination for children aged 18 months began in Australia from November 2005. The aim of this study was to compare the current incidence and outcomes of congenital and neonatal varicella in Australia with similarly collected data from 1995 to 1997. METHODS Active national prospective surveillance was carried out for congenital and neonatal varicella using t...
To the Editor: Varicella is the leading cause of vaccine-preventable death among children in the developed world. Adults with a definite history of chickenpox are usually immune, and 71% to 93% of adult patients without a definite history of varicella are also seropositive. A serologic test may thus be cost-effective for determining varicella zoster virus (VZV) immunity in adults with a negativ...
Varicella in childhood is a self-limiting disease, which usually follows a benign course. However, complications, although rare, may have serious consequences. Ischaemic stroke secondary to post varicella angiopathy is a well-described complication and is estimated to account for up to a third of all strokes in infants. We present three previously healthy children who presented to our centre wi...
