Background: Dengue hemorrhagic fever (DHF) is still a public health problem in West Kalimantan especially at Singkawang municipality. Singkawang is an endemic of DHF with an increasingly of incidence rate (IR) and case fatality rate (CFR) every year. In 2010, IR of DHF is 60,21/100.000 people, CFR=2,73%. The distribution of cases is in all five subdistricts. Objective : To identify and analysis risk factors related to DHF at Singkawang municipality with spatially analysis. Method: This was an observational study with case control design involving 220 respondents (total sampling). The total number of cases was 110 people. Controls were neighbors of cases who were healthy. Interview has been conducted to the respondents as well as geocoordinate capture of their house by using GPS. The study used individual and spatial analysis. Individual analysis used bivariate and multivariate analysis with chi-square and logistic regression. Odds ratio (OR) was used to determine risk factors. Spatial analysis used GeoDa, SaTScan and ArcGIS. Results : The multivariate analysis showed that not using mosquito repellent devices (p value=0,008 OR=2,314 95%CI=1,248-4,292) and not eradicating mosquito nests (p value=0,046 OR=1,924 95%CI=1,012-3,659) were the risk factors for infection. Spatial analysis showed that density (coefficient=-0,4182 , standard error=0,1595, t�statistic=2,6219, probability=0,0156) was the risk factor. Most likely cluster was found in 275167 m E, 99124 m N, radius 872,03 m with total number of cases was 27 people (p=0,011 (<0,05) OR=1,91), secondary cluster in 278570 m E,100400 m N, radius 1015,47 m with total number of cases 13 people (p=0,015 (<0,05) OR=2,13). Conclusions : Not using mosquito repellent devices, not eradicating mosquito nests and density were the risk factors related to DHF at Singkawang municipality.
