Surveillance of echinococcosis in Bayingolin Mongol Autonomous Prefec-ture,Xinjiang Uygur Autonomous Region from 2017 to 2022
Objective To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture,Xinji-ang Uygur Autonomous Region from 2017 to 2022,so as to provide insights into formulation of echinococcosis control measures in the prefecture.Methods Villagers were randomly sampled using a multistage sampling method from class Ⅰ and Ⅱ echino-coccosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococ-cosis,while all patients undergoing ultrasound examinations in medical institutions in class Ⅲ endemic counties received active echinococcosis screening.In addition,livestock in centralized slaughterhouses or slaughtering sites were screened for echinococ-cosis using the palpation and necropsy method,and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs.The trends in detection of hu-man and livestock echinococcosis,detection of newly diagnosed human echinococcosis cases and detection of Echinococcus copro-antigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022.Results The mean de-tection rate of human echinococcosis was 0.13％(540/407 803)in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022,which appeared a tendency towards a decline over years(χ2trend = 1 217.21,P<0.001),and the highest detection of newly diag-nosed echinococcosis cases was seen in Hejing County(0.28％,191/67 865).The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022(χ2trend = 147.02,P<0.001),with the highest detection rate seen in He-jing County(3.44％,86/2 500),and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022(χ2trend = 302.46,P<0.001),with the highest detection rate in Qiemo County(2.74％,118/4 313).Conclusions The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture,Xinjiang Uygur Auton-omous Region from 2017 to 2022;however,there is still a high echinococcosis transmission risk in local areas.Sustainable inte-grated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.
