1. Social epidemiology of a large outbreak of chickenpox in the Colombian sugar cane producer region: a set theory-based analysis
There are few social epidemiologic studies on chickenpox outbreaks, although previous findings suggested the important role of social determinants. This study describes the context of a large outbreak of chickenpox in the Cauca Valley region, Colombia (2003 to 2007), with an emphasis on macro-determinants. We explored the temporal trends in chickenpox incide

2. Uso de modelos de análise de decisão nos programas de vacinação contra a varicela / Use of decision analysis models in the programs of vaccination against varicella
BACKGROUND: The choice between different decision analysis models introduces variability in the results of economic evaluations. Static models do not take into account the indirect effects of vaccination, thus compromising the overall assessment of vaccination benefits. This work developed two models one dynamic and another static to conduct cost-effectivene

3. Study of predictive factors of severity and death due to chickenpox in residents of Greater Sao Paulo Metropolitan Area, 2003 / Estudo de fatores preditores de gravidade e óbito por varicela em residentes da região metropolitana da grande São Paulo (SP), 2003
Introduction: Chickenpox is a benign exanthematous disease of childhood, whose primary infection is caused by the Varicella-zoster virus. In the State of São Paulo, in 2003, 58,972 chickenpox cases were notified following outbreaks, configuring a hyperendemic year for the disease. From a total of 60 deaths in the whole State, 47 happened in children up to 4

4. Varicella-Zoster in children attended in day cares of Taubaté / "Varicela -Zóster em crianças de creches municipais de Taubaté"
Objective: To evaluate the morbidity associated to varicella in day cares centers of Taubaté and the parent s knowledge about the disease. Subjects and Methods: Cross-sectional study, including 664 children that had varicella after admission to the day care centers. Parents of children were interviewed by one of the participant of the study that filled in p

5. Molecular epidemiology of varicella-zoster virus in East London, England, between 1971 and 1995.
The molecular epidemiology of varicella-zoster virus in London, England, between 1971 and 1995 was examined by using two informative polymorphic markers, variable repeat region R5 and a BglI restriction site in gene 54. Viruses from 105 cases of chickenpox and 144 of zoster were typed. Two alleles of R5, A and B, were found at prevalences of 89 and 6%, respe

6. Social epidemiology of chickenpox in two British national cohorts.
STUDY OBJECTIVE--To provide a quantitative description of factors independently predictive of reported chickenpox infections in two national cohorts of British children. DESIGN--Longitudinal cohort study design employing logistic regression analysis of data obtained in the 1970 British Births Survey (later to become the Child Health and Education Study, CHES

7. Mass vaccination to control chickenpox: the influence of zoster.
The impact of transmission events from patients with shingles (zoster) on the epidemiology of varicella is examined before and after the introduction of mass immunization by using a stochastic mathematical model of transmission dynamics. Reactivation of the virus is shown to damp stochastic fluctuations and move the dynamics toward simple annual oscillations

8. Preventing Varicella-Zoster Disease
Varicella-zoster virus (VZV), the cause of chickenpox and shingles, is a pathogen in retreat following the introduction of mass vaccination in the United States in 1995. The live attenuated Oka vaccine, which is safe and immunogenic, gives good protection against both varicella and zoster in the short to medium term. It has undoubtedly been highly effective

9. Epidemiology of multiple sclerosis in the north-east (Grampian region) of Scotland--an update.
The north-east of Scotland (Grampian Region) has undergone three incidence and prevalence surveys, including the present one, since 1970. Results from these indicate a true increase in the prevalence of the disease in the region. The incidence of the disease has remained continuously high and shows a slightly upward trend. Literature on the subject of repeat
