Helminth-protozoal infestations in preschoolers of the Astrakhan region

Objective: to study and analyze the clinical and epidemiological situation on the incidence of parasitic invasions in preschool children in the Astrakhan region.

Materials and methods. The research was conducted at the Department of Infectious Diseases and Epidemiology of Astrakhan State Medical University, on the basis of the epidemiological department of the Federal Budgetary Institution of Health «Center for Hygiene and Epidemiology in the Astrakhan Region».

Results. 17.8% (884 people) of protozoan cases were detected, of which the majority were lamblia — 96.8% (856 people); in rare cases, amoebas were recorded — 2.5% (22 people) and in isolated cases — blastocysts — 0.7% (6 people). The structure of helminthiasis incidence in children is completely different, with a total of 82.2% (4,098 people) of cases identified, including enterobiasis — 99.1% (4,066 people), ascariasis — 0.7% (30 people), toxocariasis — 0.1% (4 people), trichuriasis and diphyllobothriasis — 0.02% each (1 person each).

Conclusions. Enterobiasis was detected in most cases in preschool children, with infection rate being 99.1%. The structure of protozoan morbidity among preschool children, compared to helminthiasis, is several times smaller and amounts to 17.8%, of which giardiasis was most frequently identified (96.8%). The most common patient complaints were lack of appetite, restless sleep, loose stools, nausea, and weakness.
