BACKGROUND In 2004, routine varicella vaccination was recommended in Germany for children 11-14 months of age with one dose, and since 2009, with a second dose at 15-23 months of age. The effects on varicella epidemiology were investigated. METHODS Data on varicella vaccinations, cases and complications were collected from annual parent surveys (2006-2011), monthly paediatric practice surveil...

BACKGROUND Varicella is a common childhood disease. Only 5% of first varicella-zoster-virus infections occur asymptomatically. Most data on the burden of varicella stem from health service databases. This study aims to provide insight in the burden of varicella from a parent's perspective including cases outside the healthcare system. METHODS An internet questionnaire was developed for parent...

Persistent multiple pulmonary nodules were observed on the chest X ray of a nonimmunocompromised woman 6 months after she was treated with acyclovir for a varicella-related myelitis without respiratory symptoms. Early antiviral therapy given for varicella infections might decrease the intensity of clinical symptoms without actually preventing the occurrence of varicella-zoster virus-related les...

Varicella (chickenpox) is a highly contagious disease caused by varicella zoster virus (VZV). After infection, the virus remains dormant in sensory dorsal root ganglia. Reactivation of latent VZV is associated with cutaneous disease occurring in $1 dermatomes, termed herpes zoster (HZ). Historically, HZ has been considered significantly less infectious than varicella and has not been thought to...

INTRODUCTION Varicella is an acute disease with significant morbidity. However, there is little knowledge on the seroepidemiology of the disease in Singapore. The objective of this study was to assess the seroprevalence of varicella zoster virus (VZV) antibodies in military recruits in Singapore and to ascertain the predictive value of a self-reported history of varicella. The latter is a possi...

Background.  In the United States, measles, mumps, rubella, and varicella immunity is now primarily achieved through vaccination. Monitoring population immunity is necessary. Methods.  We evaluated seroprevalence of antibodies to measles, mumps, rubella, and varicella using the National Health and Nutrition Examination Survey during 2009-2010. Results.  Measles, mumps, rubella, and varicella se...

Varicella (chicken pox) is a highly contagious disease which is caused by Varicella Zoster Virus (VZV), a ubiquitous human α herpes virus. Nosocomial varicella in hospital employees can be costly to the hospital and disruptive to patient care. This case report describes an occupationally related outbreak of chickenpox in hospital staff and the lessons which were learnt by the hospital during th...

We describe the case of an eight-year-old boy with X-linked agammaglobulinemia who developed mild varicella despite regular intravenous immunoglobulin (IVIG) therapy. He maintained protective antibody levels against varicella and the previous batches of IVIG that he received had adequate varicella-specific IgG levels. The case illustrates that IVIG may not prevent VZV infection.

Ninety throat swabs from 30 healthy children who received varicella vaccine were tested for varicella zoster virus DNA by the polymerase chain reaction. Seroconversion was observed in 27 of 30 (90%) vaccinees. The positive rates were 7.4% (2/27) at one week and 0% (0/27) at four weeks after vaccination. These rates were considerably lower than those in normal children with varicella.
