THE ACTUAL STATUS OF TOXOCAROSIS INCIDENCE IN THE CHUVASH REPUBLIC

Abstract

Toxocarosis is helminthosis caused by representatives of Nematoda type, manifested by nonspecific symptoms (from allergic manifestations to involvement of the lungs, eyes, the brain and other organs), depending on the localization of the larva in the human body. Currently, in the Russian Federation there is a tendency to increase the incidence, which makes it necessary to analyze the actual situation for this helminthosis. The aim of the study is to assess current epidemiological situation on the incidence of toxocarosis in the Chuvash Republic in the period from 2008 to 2021. The paper analyzes statistical data on the incidence of toxocarosis in the Chuvash Republic (Russia) from 2008 to 2021. During the period under study, the incidence of toxocarosis ranged from 0.91 to 6.74 per 100 thousand of population and made 4.09±0.44 per 100 thousand of population, and a decrease in this indicator was also noted in the republic over the past 13 years. However, the incidence of toxocarosis in Chuvashia remains at a level exceeding that of the average in Russia. A high incidence of toxocarosis was found to be confined to forest-growing areas (the Volga oak-forest-steppe, the South-eastern steppe and the South-western steppe regions), in which the soil-forming materials are mainly clays and loams.
