[Spatial and temporal characteristics of HIV/AIDS in Hubei province, 2010-2013].
Objective:To understand the spatial and temporal distribution of HIV/AIDS in Hubei province, and provide scientific evidence for the prevention and control of AIDS.Methods:GeoDa software was used for autocorrelation analysis, SatScan 9.2 software was used for statistical analysis of spatial scanning, and finally geographic information system was used for visualization.Results:A total of 6 952 HIV/AIDS cases were reported during 2010-2013 in Hubei, and the spatial autocorrelation analysis showed that GlobalMoran's Iindex was 0.266 (P<0.05), indicating that there was a positive spatial autocorrelation of HIV/AIDS. GlobalMoran's Iindex increased year by year (P<0.05), indicating that the increased spatial aggregation of HIV/AIDS during 2010-2013. The localMoran's Iindex showed that " high-high" clustering areas were in Wuhan, and the number of " high-high" clustering areas increased during 2010-2013. Moreover, the " high-high" clustering areas expanded from Wuhan to surrounding areas. Spatial and temporal scan analysis revealed that 19 counties in Wuhan, Huangshi, Ezhou, Xianning with a radius of 60.01 km (LLR=625.14,RR=3.23) were the main spatial and temporal clustering area during 2012-2013.Conclusion:The spatial changes of HIV/AIDS seemed to be regular from 2010 to 2013 in Wuhan, spatial correlation at provincial level decreased and the " high-high" clustering areas gradually expanded from Wuhan to surrounding areas, indicating that it is necessary to strengthen the AIDS prevention and control in these areas in Hubei.
