KNUDSON, ANGÉLICA et al. Frequency of E. vermicularis infection in rural schoolchildren in Quipile, Colombia, 2001. Rev. salud pública [online]. 2003, vol.5, n.1, pp.87-99. ISSN 0124-0064.

Objectives To study the prevalence of Enterobius vermicularis infection in children aged 3 to 14 years in a rural zone of the town of Quipile , Colombia. Methods 159 children from 14 villages, with a homogeneous distribution ac­cording to their degree of scholarity, were studied. The detection of En­terobius vermicularis eggs was done by the Graham method. The design was a cross-sectional descriptive study, for which a convenience non-prob­abilistic sampling was carried out. Fisher´s exact test and X² were performed for data analysis. Multivariate analysis by multiple correspondences was also carried out. Results 2,5 % of the children were found to be infected with E. vermicularis and 5 % with Ascaris lumbricoides . This frequency is low when compared to reports from other authors; one of the possible causes is the sampling method used. Conclusions Deficient sanitation conditions of the population studied as well as the low frequency of anal hygiene practices may represent behav­ioural risk factors which favour the transmission of this helminth.
