Epidemiological aspects of echinococcosis in the Kyrgyz Republic

In many regions of Central Asia and Russia, an increase in the number of cases of echinococcosis has been observed in recent years. The postoperative mortality rate of surgical patients with cystic echinococcosis has so far averaged 2,2%, and in 6,5% of cases there have been recurrences after surgery requiring a long recovery period. The goal of the research was to analyze the structure of morbidity and prevalence of echinococcosis in the Kyrgyz Republic. The analysis of the official data of the National Statistical Committee of the Kyrgyz Republic on morbidity and prevalence of infectious and parasitic diseases, including echinococcosis for the period from 2001 to 2022 was carried out. A retrospective analysis of epidemiological and laboratory-instrumental data of case histories of 1024 operated patients with echinococcosis in the secondary level hospital (City Clinical Hospital №1, Bishkek) for the period from 2018 to 2022 was performed. The incidence of echinococcosis in the Kyrgyz Republic from 2001 to 2021 increased 2.6-fold with an annual growth rate of 14,6%, reaching 19,2 per 100 thousand population by 2015 with a subsequent decrease in 2021 to 9,9 per 100 thousand population. The decrease in the number of new cases of echinococcosis in 2019- 2021, in our opinion, indicates an insufficient level of diagnostic measures, population migration and deterioration of the socio- economic and sanitary-epidemiological state of the country. Echinococcosis occurred more frequently in persons of working age (mean age 35±16 years), mostly inhabitants of rural areas (67,3%), having close contact with flesh-eating animals (58,4%). The prevalence of complicated forms of echinococcosis among the operated patients was 64,7%, which increased the period of hospitalization by 5,3±2,4 days
