“…74.6-78.7%) came to a same conclusion with Iranian's rate of VZV prevalence (Siennicka et al, 2009). Results from that study demonstrated a close relationship between seroprevalence and age but no correlation with gender, rural/urban areas and geographical regions of Poland (Siennicka et al, 2009).…”

Varicella zoster virus (VZV) causes chicken pox as a primary infection following which it becomes latent in neurons. It may then reactivate to cause shingles (herpes zoster). Severity of lesions and VZV pathogenicity are depended on the host's immune response and variant in VZV Dr Athina Myrto ChioniIdentification of VZV seroprevalance rate in general population may lead to develop new health strategic managements such as vaccination. Therefore, we aimed to provide a systematic review of the seroprevalence of VZV infection among Iranian population and estimate age-and gender-specific prevalence of VZV.Keywords "seroprevalence", "varicella zoster virus", and "Iran" were searched in international electronic databases and also in national Persian databases. Twenty two pooled studies among 262 total studies containing (240 published articles, 18 dissertations, and 4 proceedings abstracts) from 1992 to 2014 with total sample size of 7867 individuals were included in the final review.Data was analyzed using random effect method. The heterogeneity was calculated using I-square statistics.The overall IgG seroprevalence rate of VZV infection in general population of Iran was 78.50% (95% CI; 77.74% -79.25%). There was significant heterogeneity among the studies (P<0.0001; I²=99.4%). Furthermore, the relative risk of VZV infection is high in females (80.47%, 95% CI; 79.40% -81.54%) and older adults (95.30%, 95% CI; 94.11% -96.48%).Our results may represent a true background and estimation of VZV infection in Iran and generate the cost-benefits immunization program. Moreover, the ensuing data suggests further attention on disease seroprevalence in order to obtain efficient data for therapeutic intervention targeted against VZV.

“…Their results have indicated a low level of immunity, e.g. 97.31% among subjects aged 18-19, or 95% and 98% among children and teenagers (aged 1-19), respectively [11,12]. A review of the serologic studies on the immunity to varicella in the European countries among various age groups confirms the existence of considerable differences.…”

Objectives: The aim of the study was to evaluate the following: i) number of midwives and nurses at risk for contracting varicella; ii) effectiveness of infectious disease prevention among healthcare personnel; iii) attitude of healthcare personnel towards immunization. Material and methods:A total of 524 midwives and nurses from obstetric, neonatal, and pediatric wards were investigated. Quantitative data analysis was performed.Results: Overall, 14.7% potentially seronegative respondents were identified. Out of those with a positive history of varicella, 6.56% contracted the disease after starting work, and > 70% had contact with the varicella-zoster virus. Overall, 9.54% of the respondents had a history of varicella, 3.12% were informed about the possibility of immunization, and 1.56% of those with a negative history of the disease were offered a state-funded vaccine. In the same group, the number of vaccinated people amounted to 13.28%, and 26.13% would accept a state-funded vaccine. Conclusions:Varicella may constitute a significant threat to maternal and fetal health at obstetric, neonatal, and pediatric wards, which must be considered when providing care to women in the reproductive age. Occupational health physicians should confirm the immunity status of the patients and suggest immunization to seronegative subjects. Regular workshops are necessary to update the knowledge of medical professionals and patients in order to shape their attitudes and beliefs about immunization.

“…The bio-bank contained samples collected mainly for the purpose of routine check-ups or investigations before surgical procedures. Details of the sample collection and laboratory testing are available elsewhere [42]. Altogether 1244 samples were included in the study, the number per year ranged from 108 to 500.…”

The dynamics of the infectious disease transmission are often best understood by taking into account the structure of population with respect to specific features, for example age or immunity level. The practical utility of such models depends on the appropriate calibration with the observed data. Here, we discuss the Bayesian approach to data assimilation in the case of a two-state age-structured model. Such models are frequently used to explore the disease dynamics (i.e. force of infection) based on prevalence data collected at several time points. We demonstrate that, in the case when the explicit solution to the model equation is known, accounting for the data collection process in the Bayesian framework allows us to obtain an unbiased posterior distribution for the parameters determining the force of infection. We further show analytically and through numerical tests that the posterior distribution of these parameters is stable with respect to a cohort approximation (Escalator Boxcar Train) of the solution. Finally, we apply the technique to calibrate the model based on observed sero-prevalence of varicella in Poland.
