[Intestinal parasites in secondary school students in the Martin District]

The authors report on the prevalence of intestinal parasites in 1763 students of selected secondary schools in District Martin from 1988 to 1990 as continuation of parasitologic surveillance of pre-school children collectives and of elementary school pupils. The situation in occurrence of geohelminthiasis in the investigated group of students is considered to be very favorable and could reflect, in some degree, the parasitologic surveillance and treatment of positive cases in the seventies. The prevalence of intestinal protozoa, especially Giardia intestinalis, is in examined students only a little lower as the values given by our authors for population of children. This indicates a shift of epidemiologic importance from geohelminthiases towards the protozoal infections. (Tab. 5, Ref. 18).
