Objective To analyze the spatial and temporal distribution characteristics of dengue fever (DF) in Guangdong province, China during 2006-2011 and to provide a scientific basis for the prevention and control of dengue. Methods The annual incidence of DF in the county-level areas (counties or districts) of Guangdong province was determined during 2006-2011. The geographic pattern of DF incidence was examined by spatial autocorrelation analysis. Results The incidence rates of DF in the Pearl River Delta region and Han River Delta region were >4/105 and >2.5/105, respectively. Moran'sⅠ statistics of DF distribution were significant from 2006 to 2007 (P=0.005) and from 2009 to 2011 (P=0.001), but it was not significant from 2007 to 2008 (P=0.814). Conclusion The risk of DF is not randomly distributed among the county-level areas in Guangdong province, and the Pearl River Delta region and Han River Delta region are high-risk areas.
