“…In other temperate countries the age‐specific seroprevalence is similar. Fairley & Miller (1996) found in their UK study that > 90% of individuals had been infected by 15 years of age, and Eguiluz et al (1987) demonstrated 80% seroprevalence to VZV by seven years of age in Spanish children. Seroprevalence is also high in Japanese children ( Taylor‐Wiedeman et al .…”

Varicella zoster virus (VZV) predominantly affects children in temperate countries, with near-universal seroconversion occurring by late childhood. However, in tropical regions, VZV infection is common in adolescents and adults. This review identifies age-related VZV seroprevalence patterns in a number of Asian countries which indicate that seroconversion in tropical countries occurs at a later age than in temperate countries. Seasonal and regional variations in acute disease within some Asian countries suggest that temperate climates might favour transmission of the varicella virus, with incidence peaking during cooler months and in cooler, more temperate regions. VZV infection is often more severe in adults than in children, suggesting that tropical countries may be at risk of greater morbidity and mortality as a result of later-age seroconversion. Susceptibility of pregnant women and their infants, and of people infected with HIV/AIDS is also cause for concern. Vaccination may be beneficial in reducing the impact of VZV in Asian populations.

“…In temperate climates in the absence of vaccine, varicella is a near-universal and a relatively banal childhood infection with a high burden of morbidity but a low case fatality rate. The primary manifestation of varicella-zoster virus (VZV) infection is experienced in childhood before the age of 4 years, with annual peaks occurring in the late winter and early spring (Meunch et al 1986;Preblud 1986;Eguiluz et al 1987;Taylor-Wiedeman et al 1989;Trlifajova et al 1989;Heath & Kangro 1990;Schmid & Jumaan 2010). Although a delayed onset of natural immunity and no apparent seasonality occur in tropical regions, around 20% of the population remains susceptible into adulthood (Ooi et al 1992;Garnett et al 1993;Barzaga et al 1994;Arvin 1996;Lee 1998;Lolekha et al 2001;Schmid & Jumaan 2010) when outbreaks or complications such as pneumonia, hospitalisation, and a greater burden of care can result (Almuneef et al 2006).…”

Abstractobjectives To determine the seroprevalence of varicella-zoster viral (VZV) infections in schoolchildren from the Cochabamba region (Bolivia), and its association with socio-demographic variables, socio-economic status and geographical location.methods Seroepidemiological survey (n = 436) on VZV of schoolchildren living in the Cochabamba region of Bolivia in 2010. An ELISA test was used to measure varicella antibodies. Parents or guardians completed a questionnaire regarding socio-demographic information (age, gender, living area, parental educational level, presence of siblings and number of family members in the household), and a blood sample was collected from each child to check for VZV antibodies. A descriptive and bivariate analysis was performed.results The global prevalence of VZV was 78.2% (95% CI 74.3-82

“…In temperate regions, varicella is a disease of preschool and school-age children. [3][4][5][6][7][8] In tropical regions, varicella typically occurs at a later age [9][10][11][12] with many cases in adolescents and adults who are at risk of developing more severe disease. A recent study in Bangkok also showed that 70.4% of the population younger than 20 years of age were seropositive, and this increased to 98-100% by the age of 40.…”

Abstract. Blood samples were collected from healthy subjects, aged 9 months-29 years in urban and rural communities from 4 distinct regions in Thailand, to determine the seroprevalence rate of varicella-zoster virus (VZV) antibody and its relationship with demographic, climatic, and socioeconomic factors. The overall seroprevalence rate was 52.8% and increased from 15.5% in the 9-month to 4-year-old group to 75.9% in the 20-29 year-olds. The ageadjusted seroprevalence was significantly higher in the cooler than in the warmer regions. In the warmer regions only, the age-specific seroprevalence was significantly higher in the urban population than in the rural population. In Thailand, climate is the main determinant of VZV seroprevalence. The delayed onset of natural immunity is more marked in warmer climate areas. Population density is a secondary determinant; in the warmer areas, the pattern of adolescent and adult susceptibility was greater in rural than in urban areas.
