Chickenpox

Varicella is one of the most common infectious diseases, with a worldwide distribution. According to a WHO position paper, the global annual disease burden of varicella is estimated to be million cases. Varicella-related hospitalization rates differ widely worldwide. Varicella may potentially afflict any organ; hematological, neurological, respiratory, cutaneous, hepatic, gastrointestinal, urinary, and bone complications are the most frequently reported. The incidence of varicella complications differs among scientific reports. For example, the pooled prevalence of neurological complications resulting from a systematic review of the literature identifies the likelihood of pediatric neurological complications in the range of Patients with a history of underlying malignancy, steroid use or immunosuppressive therapy, HIV infection, or solid organ transplantation are susceptible to disseminated varicella due to impaired cellular immunity.

Infection with varicella zoster virus VZV causes varicella chickenpox , which can be severe in immunocompromised individuals, infants and adults. Primary infection is followed by latency in ganglionic neurons. During this period, no virus particles are produced and no obvious neuronal damage occurs.

Chickenpox (Varicella) Vaccines

Metrics details. Chickenpox vaccine is not included in the routine childhood vaccination programme in Sweden. The aim of this study was to estimate the baseline of national chickenpox disease burden, as comprehensive studies, required for an assessment regarding vaccine introduction, are lacking. From each data source, records regarding chickenpox were identified and extracted, either using relevant diagnosis codes ICD or key words. A descriptive analysis with regards to number of cases and incidence, severity, and seasonality, was carried out covering the time period to


Cohort studies may help to clarify the nature of the association between Varicella-Zoster Virus and Three Other Herpesviruses among Adults with Zoster Vaccines as Immune Adjuvants in Glial Tumor Treatment? Article.


Varicella zoster virus-associated morbidity and mortality in Africa – a systematic review

Universal childhood vaccination against varicella began in the United States as a 1-dose schedule in , changing to a 2-dose schedule in The exogenous boosting hypothesis, which postulates that reexposure to circulating wild-type varicella delays the onset of herpes zoster, predicts a transient increase in the incidence of herpes zoster, peaking in adults 15—35 years after the start of varicella vaccination. This was a retrospective study of administrative claims data from the MarketScan Commercial and Medicare databases between —

Chickenpox , also known as varicella , is a highly contagious disease caused by the initial infection with varicella zoster virus VZV. Chickenpox is an airborne disease which spreads easily from one person to the next through the coughs and sneezes of an infected person. Since its introduction in , the varicella vaccine has resulted in a decrease in the number of cases and complications from the disease. Chickenpox occurs in all parts of the world. The early prodromal symptoms in adolescents and adults are nausea, loss of appetite, aching muscles, and headache.

Varicella-zoster virus VZV causes chickenpox and may subsequently reactivate to cause herpes zoster later in life. The exogenous boosting hypothesis states that re-exposure to circulating VZV can inhibit VZV reactivation and consequently also herpes zoster in VZV-immune individuals. Using this hypothesis, mathematical models predicted widespread chickenpox vaccination to increase herpes zoster incidence over more than 30 years. Some countries have postponed universal chickenpox vaccination, at least partially based on this prediction.
