Abstract:

At present, the problem of echinococcosis and alveococcosis remains relevant both for the Kyrgyz Republic (KR) and for endemic in this nosology Alai district of Osh region and Kochkor district of Naryn region. An important component of the epidemiological surveillance of cystic (CE) and alveolar echinococcosis (AE) is instrumental monitoring (screening) for the purpose of early diagnosis and determining the accuracy of the distribution map. The article presents the results of an instrumental (ultrasound) examination of a conditionally healthy population of 56 villages in two districts of the Kyrgyz Republic (Alai and Kochkor) for 2016. The study revealed a high prevalence of both alveolar and cytic echinococcosis. For AE, there was a prevalence of 7.1% [5.7%-8.9%] in Alay region which was significantly higher than in in Kochkor region where the prevalence was of 3.6% [1.8%-3.9%] p<0.01. For CE the prevalence was lower in Alay with a value of 0.9% [0.4%-1.6%] while in Kochkor prevalence was 1.7% [1.0%-2.7%), p<0.01.The men were more likely to have AE and mostly in Kochkor. The results obtained in the course of the study may indicate a high level of actual morbidity of the population with this helminthiasis in the population under study and show the need for targeted early anti-epidemiological and preventive measures.
