TL;DR: A spatial-temporal model of schistosomiasis japonica transmission, a disease caused by parasites that are transported via surface water and that live in both snail and human hosts, suggests that better understanding of intervillage connectedness can be exploited in the design of cost-effective control strategies.
Abstract: Spatial interaction and connectivity are important factors in the spread of infectious diseases. We developed a spatial-temporal model of schistosomiasis japonica transmission, a disease caused by parasites that are transported via surface water and that live in both snail and human hosts. The model employed a spatial interaction matrix based on neighborhood relationships and hydrologic connectivity to assess the effect of intervillage parasitic transport on disease transmission and control. Satellite remote-sensing data served as input to the model for predicting snail density within each village, and for deriving a digital elevation model that was used to quantify hydrologic connectivity. Simulations of the model with varying levels of connectivity and in the presence and absence of chemotherapy control were run for 227 villages near Xichang City, in southwest Sichuan province, China. Increasing connectivity resulted in a geographic clustering of parasites within particular villages that produc...

TL;DR: In his Perspective “Waterborne infectious diseases—could they be consigned to history?” (Special Issue on Freshwater Resources, 25 Aug., p. 1077), A. Fenwick presents a hopeful outlook, based principally on drug effectiveness and distribution, for gaining control over serious waterborne diseases.
