Objective Analysis of temporal and spatial epidemiological characteristics of HIV positive prostitutes and AIDS epidemic reports in Guigang City, Guangxi, from 2007 to 2017, and providing scientific basis for the prevention and control of HIV/AIDS in future.

Methods The township as a unit, ArcGIS10.2 was used analysis of epidemiological characteristics of time and space.

Results The global autocorrelation showed that the incidence of prostitutes existed spatial aggregation in 2015 and HIV/AIDS in 2007, 2009, 2010, 2011, 2013 ( P<0.05). GIS map showed that the majority of HIV/AIDS in Guigang City from 2007 to 2017 was in the northeast, followed by the western and southwest. The hotspot distribution was basically consistent with that of positive prostitutes. Analysis from the direction distribution (standard deviation ellipse) showed that the scope of reported incidence of AIDS epidemic was basically consistent with that of positive prostitutes.

Conclusion There are hot spots in the spatial distribution of AIDS reports and positive prostitutes in Guigang. The hotspot distribution is consistent .The key prevention and control people, area and time of HIV/AIDS should be confirmed according to the findings in Guigang, and rational resource allocation and regional prevention and control measures were put forward.
