一般講演(ポスター発表) PB1-182 (Poster presentation)
As a zoonotic disease, rabies has been found worldwide in more than 150 countries and territories. Being rabies free for more than 50 years, positive cases were rediscovered in Taiwan in July 2013. Since then, 408 cases were reported till December 2014. To start up prevention works like distributing vaccine-laden baits, spatial patterns and dynamics of the disease should be assessed. Also, to prevent future outbreaks in rabies-negative area, such as northern Taiwan, understanding of the possible infection paths is required. This study tends to find out important properties and patterns of the positive cases. We used the point data from July 2013 to June 2014, examining positive cases’ elevations, hotspots, and the spatial expansion pattern. The preliminary result shows that (1) most positive cases appeared at low elevation areas, (2) multi-origins hotspots were found and (3) rabies in western Taiwan express a radial expansion from hotspots, but in eastern Taiwan the disease first headed south before it went north. These results point out the importance of lowland regions around hotspots, which should set up sanitary cordon. The different spreading patterns might due to differences in topography. Important environmental factors affecting the host animal movements should be studied.
