Abstract

Introduction: Dengue hemorrhagic fever (DHF) is a public health problem in Jakarta. Its outbreak seems to be highly associated with the rainfall rate (RR) and Aedes aegypti distribution. However, due to global climate change in dry-rainy season, the DHF trend has become irregular. The aim of this study was to determine the trend of DHF in Jakarta and its association with the RR and Ae. aegypti distribution represented by house index (HI) in order to establish an early warning system (EWS).Methods: This study used secondary data of DHF cases (NC), HI, and RR measurement from each region of Jakarta in 2008-2010. One-way anova test was used to analyze the relationshipbetween NC, HI, and RR.Results: It showed fluctuative occurences of DHF, with the peak number of NC has been progressively shifted from May 2008 to earlier in March 2009 and 2010. No significant difference between NC and RR (p=0.073) and between NC and HI (p=0.213) but there was significant difference between RR and HI (p<0.001).Conclusion: NC was not associated with RR and HI but there was association between RR and HI. The EWS was proposed to be performed in the beginning of November before the raising in RR and HI in the later months.
