Objective: To analyze the spatial-time distribution characteristics of schistosomiasis in Jiangling County, Hubei Province from 2006 to 2011.
Methods: The surveillance data of schistosomiasis of Jiangling County from 2006 to 2011 were collected, and a spatial database was established. The spatial-time permutation cluster analysis was performed by SaTScan 9.1.1 to detect the spatial-time cluster areas of schistosomiasis, and a risk map was drawn by ArcGIS 10.0.
Results: Compared to 2006, the infection rates of human, cattle and Oncomelania hupensis snails decreased by 47.67%, 93.34% and 52.41%, respectively in 2011. The space-time permutation clustering analysis of the infection rates of human, cattle and snails showed 4, 3 and 4 clusters, respectively, and all the clustered areas were distributed in inner embankment areas.
Conclusions: From 2006 to 2011, the schistosomiasis endemic situation presents a decline trend in Jiangling County. The detected cluster areas are the important areas for schistosomiasis control. The space-time permutation statistics could be used in the analysis of endemic situation of schistosomiasis.

Objective: To identify the spatial distribution pattern of spread in Hubei Province, so as to provide insights into precision snail control in the province.
Methods: Data pertaining to emerging and reemerging snails were collected from Hubei Province from 2020 to 2022 to build a spatial database of snail spread. The spatial clustering of snail spread was identified using global and local spatial autocorrelation analyses, and the hot spots of snail spread were identified using kernel density estimation.

Objectives: Schistosomiasis is a zoonotic infectious disease that seriously harms people's physical and mental health. As early as 1985, the WHO suggested that health education and health promotion should be the focus of schistosomiasis prevention work. This study aimed to explore the effect of health education on controlling the risk of schistosomiasis transmission after schistosomiasis blocking and to provide a scientific basis for the further improvement of intervention strategies after schistosomiasis interruption in China and other endemic countries.

Objective: This study aims to explore the spatiotemporal distribution of schistosomiasis in Jiangling County, and provide insights into the precise schistosomiasis control.
Methods: The descriptive epidemiological method and Joinpoint regression model were used to analyze the changes in infection rates of humans, livestock, snails, average density of living snails and occurrence rate of frames with snails in Jiangling County from 2005 to 2021. Spatial epidemiology methods were used to detect the spatiotemporal clustering of schistosomiasis transmission risk in Jiangling county.

A new formulation (suspension concentrate, SC) of PBQ [1-(4-chlorophenyl)-3-(pyridin-3-yl) urea] was used in water network schistosomiasis-endemic areas to test its molluscicidal efficacy and the acute toxicity to crustaceans. PBQ (20% SC), 26% metaldehyde, and niclosamide suspension concentrate [MNSC (26% SC)] were used both in ditch and field experiments for the molluscicidal efficacy comparison. Acute toxicity tests of two molluscicides were conducted using and .
