title: Prevalence and risk factors for intestinal parasitic infections in a rural community in "consolación del sur" municipality, cuba.
abstract: Intestinal parasites are very common infections worldwide and they are responsible for significant public health problems. The World Health Organization estimates that one-third of the world population is infected and some epidemiologic factors related to the transmission have been identified. The purpose of this investigation was to study the prevalence of intestinal parasitic infections in people living in the rural community of "El Canal", Consolación del Sur municipality and the association with some epidemiologic risk factors. All participants were subjected to three methods of parasitological examinations on the stool samples and by immunodiagnostic tests which allow the detection of excretory-secretory antigens of adults with Fasciola hepatica. The global prevalence rate of intestinal parasitic infections (IPIs) was 18%, and 16.7% for protozoan infections, while the rate of helminth infection was lower (5.3%) in the population studied. The univariate analysis identified three factors associated with intestinal pathogenic protozoan infections which include livestock work, drinking water from well\river and eating unwashed fruits\vegetables. The multivariate analysis using introduction test logistic regression ratified the association of these risk factors. Contrary to what have been published in the majority of Cuban studies carried out in rural places, a higher prevalence of protozoan than helminth infection was found. This discrepancy may be explained because the majority of the workers in this rural community were stock-breeders and they are not involved in other agricultural work. The identification of risk factors is important in order to design appropriate strategies for control of IPIs in communities.
