Abstract:

The Cattle is one of the important middle hosts of schistosomiasis in China. In this study, the infected cattle data of ten counties in Jianghan Plain(Hubei Province, China) were geospatially visualized between 2008 and 2012, the micro-geographical distribution and the temporal heterogeneity of those infected cattle were also analyzed for schistosomiasis control strategies design. The results showed the high-risk cluster areas of infected cattle mainly distributed in the Four-Lakes Region, which particularly included the inside embankment areas in the countyies of Shashi, Jiangling, Gong’an and Qianjiang and the outside embankment areas of city of Shishou. The cattle infected high risk period is 2008 and 2009, and the cattle infected areas also decreased later after 2009. The cattle infected ratios(infected individuals in all cattle) decreased significantly with time increasing between 2008 and 2012. The cattle infected areas can be divided into three types: inside embankment areas, outside embankment areas and hilly areas. Multi-level model results showed the area types and yearly variations could significantly affect the cattle infected ratios(type = -0.3, P < 0.001; year*type=-0.07, P < 0.01). The cattle infected ratios were highest in inside embankment areas, middle in outside embankment areas, and lowest in hilly areas. This study showed the cattle infected ratios in this region had significantly spatiotemporal heterogeneity, and those characteristics can be used in the schistosomiasis control strategies design.
