Abstract: Objective To analyze the epidemic situation and risk factors of schistosomiasis in Hubei Province from 2015 to 2022, and to provide a scientific basis for the goal of all schistosomiasis-endemic counties in the province reaching the elimination standard by 2030. Methods According to the requirements of the National Schistosomiasis Surveillance Plan (2014 edition) and National Schistosomiasis Surveillance Plan (2020 edition), the snail situation and the risk of wild fecal transmission, along with regional distribution in schistosomiasis endemic areas in Hubei Province from 2015 to 2022 were analyzed and the risk was rated. Results From 2015 to 2022, a total of 60 203 risk monitoring environments per time was carried out, with 10 223 460 frames of snails inspected, capturing 2 344 094 snails, among which 1 357 479 live snails, and an average density ranging from 0.07-0.29 snails/0.11 m2. In 2015 and 2017, 11 and 3 schistosomiasis-infected snails were detected respectively, corresponding to 3 and 2 positive snail environments. The proportion of wild feces distribution environment in the total monitoring environment showed a downward trend, with cow dung accounting for the highest proportion (69.27%). A total of 19 549 wild feces were collected, of which 78 were positive for schistosomiasis. Since 2018, only one positive cow dung was found in 2019, and none in other years. From 2015 to 2020, the density of live snails and the proportion of wild feces in the monitoring environment in each risk monitoring county (city, district) had significantly reduced, with areas of higher snail density such as Gongan County, Yangxin County with higher density of live snails decreasing to below 1 per 0.11 m2 from 2017. Among the 60 203 risk monitoring environments, 53 were identified as GradeⅠrisk (not detected since 2020), 1 999 as GradeⅡrisk, and 58 030 as GradeⅢrisk. Conclusions From 2015 to 2022, the overall schistosomiasis epidemic in Hubei Province showed a downward trend. However, the risk of schistosomiasis transmission still exists in some areas. In the future, we should continue to strengthen the epidemic monitoring in key areas, improve the sensitivity and level of monitoring, and prevent the rebound of the epidemic.

Objective To understand the change of hydrological regime in the Yangtze River and schistosomiasis endemic situation after the implementation of Three Gorges Project in Hubei Province. Methods The data of hydrological regime of the Yangtze River,schistosomiasis epidemic situation,and Oncomelania hupensis snail status were collected and analyzed in Hu-bei Province from 2002 to 2012. Results After the implementation of the Three Gorges Project in 2003,the water level of the Yangtze River slightly rose from January to March,the average water level in May and August both reduced compared with that in 2002,and the time of water withdrawal was moved up. The endemic situation of schistosomiasis showed a decline tendency in areas along the Yangtze River in Hubei Province. The positive rate of serological tests in the residents and the Schistosoma ja-ponicum infection rate in bovine decreased by 2.97%and 92.64%respectively. The numbers of human and bovine infected with S. japonicum decreased by 48.35%and 94.48%,respectively. Conclusion After the implementation of the Three Gorges Proj-ect,the schistosomiasis endemic situation shows a decline tendency in the areas along the Yangtze River in Hubei Province ,but the long-term monitoring still need to be carried out.

Objective To study the endemic trend of schistosomiasis japonica in Hubei Province,so as to provide the theo?retical basis for surveillance and forecasting of schistosomiasis. Methods The time?series auto regression integrated moving av?erage(ARIMA)model was applied to fit the infection rate of residents of Hubei Province from 1987 to 2013,and to predict the shot?term trend of infection rate. Results The actual values of infection rate of residents were all in the 95%confidence inter?nals of value predicted by the ARIMA model. The prediction showed that the infection rate of residents of Hubei Province would continue to decrease slowly. Conclusion The time?series ARIMA model has good prediction accuracy,and could be used for the short?term forecasting of schistosomiasis.

Objective To assess the schistosomiasis endemic situation in the national surveillance sites in Hubei Province, so as to provide the evidence for the prevention and control of schistosomiasis. Methods According to the national surveillance protocol,a longitudinal surveillance of endemic situation of schistosomiasis was carried out in 16 national surveillance sites from 2005 to 2010. Results In general,the positive rates of IHA,Kato-Katz technique and infection rates of Schistosoma japonicum decreased from 15.67%,10.93%and 1.71%in 2005 to 10.48%,8.54%and 0.90%in 2010,and declined by 33.12%,22.70%and 47.95%,respectively. The infection rates of S. japonicum of the male were higher than that of the female,and the peak infec-tion rates were in the groups aged above 30 years. The endemic situation of fishermen and farmers were relatively serious. The in-fection rates of S. japonicum in cattle decreased from 11.69%in 2005 to 1.41%in 2010,and declined by 88.01%(χ2 =298.79, P<0.001). The areas with infected Oncomelania hupensis snails,the densities of living snails,the rates of infected snails and the densities of infected snails decreased by 90.88%,61.66%,80.00%and 92.00%,respectively. Conclusion The schistosomiasis endemic situation in the national surveillance sites in Hubei Province mitigates in 6 years,but the prevention is still a very daunt-ing task.
