The current situation of echinococcosis in the Far East and South of Russia

Objective: to assess the epidemic situation of echinococcosis in the period 2012–2022 in the endemic territories of the Far Eastern Federal District and South of Russia. Materials and methods: based on the data of the annual statistical reporting forms No. 2 "Information on infectious and parasitic diseases", data from the Reference Center for Monitoring Larval Helminthiasis of Rostov Research Institute Microbiology and Parasitology of Rospotrebnadzor, an analysis of the incidence of echinococcosis in the territories of the Far East and South of Russia in the period 2012–2022 was carried out. For seroepidemiological examination of a conditionally healthy population by the ELISA method, the diagnostic kit "Echinococcus-IgG-ELISA-BEST" (JSC "Vector-Best", Novosibirsk) was used. Results: it is shown that the epidemiological situation of echinococcosis is characterized by pronounced territorial unevenness. In the south of Russia, epidemiological problems with echinococcosis persisted in Kalmykia (0.74–2.19 cases per 100,000 population) and in the Astrakhan region (0.60–1.48 cases per 100,000 population). Among the relatively healthy population, the average seropositivity to E.granulosus antigens in the Far East was 5.8%, in the south of Russia — 2,6%. Conclusions: the data obtained indicate an unfavorable epidemiological situation for echinococcosis in a number of regions of the Far East and South of Russia.
