Dengue fever has reemerged as a serious public health issue worldwide. The disease is endemic in more than 100 countries, with an estimated 50-100 million cases annually. It is considered endemic to Cambodia and, despite multiple control programs, the country has 10,000-40,000 hospitalized cases per year for children less than 15 years of age. In order to have control approaches that are more effective, the patterns of dengue cases in Cambodia need to be further explored. This study seeks to clarify the patterns of dengue by performing a geospatial analysis of 11 years of national surveillance data, from 2002 to 2012. Various exploratory geospatial statistical tools were used to calculate the local indicators of spatial autocorrelation and the local Gi* statistic analysis to determine significant hot and cold spots of dengue fever at the district level of Cambodia. Results found that in most years between 2002 and 2012, the two urban centers of Cambodia, Phnom Penh and Siem Reap, were significant hot spots for dengue fever. This suggests that prevention and control programs should be targeted to these two areas specifically. However, these clusters corresponded with five of the seven sentinel surveillance sites used in the country. This analysis could be only a representative of more sensitive surveillance. Expanding sentinel surveillance activities to other provinces could reveal a clearer picture of dengue fever in Cambodia.
