Objective To understand the dynamic changes of echinococcosis endemic in Sichuan Province from 2016 to 2019, in order to provide reference for further prevention and control. Methods In 2016—2019, ultrasonographic examination was carried out to detect echinococcosis in the permanent residents aged over 2 years within the surveillance sites of Sichuan Province. Feces of domestic dogs and stray dogs were collected for detection of Echinococcus coproantigen, and internal organs of livestock and rodents in the surveillance counties were examined by palpation and necropsy to identify hydatid infection. Results Population surveillance at 35 sites showed that the detection rate of new cases of echinococcosis showed a trend of decrease from 0.15% (72/48 976) in 2016 to 0.02% (13/81 725) in 2019 (P < 0.05). A total of 115 new patients were detected, of them 80.87% (93/115) were from Garze Tibetan Autonomous Prefecture. Among the new cases, 59.13% (68/115) were of alveolar echinococcosis (AE), 38.26% (44/115) cystic echinococcosis (CE), and 2.61% (3/115) were found to be extrahepatic echinococcosis. The positive rates of Echinococcus coproantigen in domestic dogs from 2016 to 2019 were 1.19% (28/2 348), 2.35% (52/2 212), 3.43% (69/2 010) and 0.95% (35/3 668), and in stray dogs 2.87%(13/453), 2.00% (8/400), 4.69% (15/320) and 0.80% (5/624), respectively, with significant difference between the years (P < 0.05), and these rates in 2019 decreased by 20% and 72% compared to 2016. During 2016—2019, the prevalence in livestock were 4.45% (146/3 283), 1.53% (50/3 273), 2.93% (75/2 564) and 2.18% (89/4 078), and the prevalence in rodents were 1.71% (123/7 204), 2.48% (185/7 470), 1.19% (67/5 613) and 1.47% (154/10 477), respectively, with significant difference between the years (P < 0.05), and the prevalence in 2019 decreased by 51% and 14% compared to that in 2016. Conclusion The detection rate of new echinococcosis cases, the positive rate of dog coproantigen, the infection rate in intermediate hosts showed a overall decreasing trend from 2016 to 2019 in Sichuan Province, but the positive rate of dog coproantigen and infection rate in intermediate hosts were fluctuated.
