Abstract

Background.-Although measles is a highly infectious disease, the live measles vaccines provides protection for ever 20 year, and immunity may be lifelong this study assessed measles seroprevalence in school children in the Cochabamba region of Bolivia. Methods.- A seroepidemiological survey of measles immunity in 5-16 year old schoolchildren (n=441) living in the Cochabamba region of Bolivia was performed in march and april of 2010, representative regional samples of school children from 14 schools were obtained a parent- administered questionnaire collected sociodemographic and tested for measles antibodies using and enzyme-linked fluorescent antibody test. The measles prevalence and corresponding the ANOVA or the kruskal-wallis test according to whether the data were distributed normally (Kolmogorov- Smirnov test p. value  0.005) plus the chi- square test of fishers exact test a needed. Results: The global seroprevalence of measles was 69.61% (95% CI 65.32-73.90and was higher in adolescents (84.16%, 95% CI 77.04- 91.28) and Spanish speakers (74.74, 95%, CI 68.56-80.92) the seroprevalence did no differ according to socio-economic status, living area, or number of family members in the household. Conclusions: This study found a high prevalence of meals susceptibility in Bolivia children thus, herd inmunity may not have been established, and some outbreak could occur. authorities should redress this situation before endemic measles transmission occurs nationally and regionally, and there is an urgent need conduct more seroprevalence studies in the region.
