Abstract:
Objective To analyze the spatial distribution characteristics ofmultidrug-resistant (MDR) tuberculosis (TB) cases in Zhejiang province in 2010-2012.Methods Data on MDR-TB cases in Zhejiang province were collected and linked to the digital map at the county and district levels.ArcGIS 10.0 software was used for spatial analysis.Results Results from the spatial autocorrelation analysis showed that spatial aggregation appeared in MDR-TB distribution during 2010-2012 while local Moran's I spatial autocorrelation analysis identified several "high incidence regions" (Wuxing,Deqing,Yuhang,Gongshu,Jianggan,Xiaoshan,Yuecheng,Shaoxing Shengzhou,Changshan,Kecheng),and "low incidence region" (Haishu).Through Getis-Ord General G spatial autocorrelation analysis,18 "positive hotspots" (Wuxing,Nanxun,Deqing,Yuhang,Shangcheng,Xiacheng,Gongshu,Jianggan,Binjiang Xiaoshan Xihu,Haining,Yuecheng,Shaoxing,Zhuji,Shengzhou,Kecheng and Suichang) and 11 "negative hotspots" (Nanhu,Haiyan,Cixi,Dinghai,Zhenhai,Jiangbei,Jiangdong,Beilun,Yinzhou,Fenghua,and Yueqing) were identified.Conclusions Spatial analysis on MDR-TB incidence implied the spatial aggregation in Zhejiang province.Data showed that the hotspots with high population density and human movement were under progressive expansion.
