The Relation Between Rainfall With Prevalence Of Dengue Hemorrhagic Fever DHF In Children Ages 5-14 Years

Dengue Hemorragic Fever DHF is one of health problems in Indonesia. DHF is often associated with climate change because it usually occurs at the beginning and at the end of the rainy season. it is shown by the high rates of morbidity and mortality. the case of DHF tends to reach its peak on January each year on wich the rainfall tends to fall. This research is observational analytic study using a case report. Samples of this study are all DHF cases in children aged 5-14 years during 2010-2012 in Haji hospital Surabaya. The result of spearman analysis showed r 0.383 p0.011 with the result obtained by linear regression0.356 with R square 0.025. There is significant relation between rainfall and DHF case. This proves that the amount of rainfall is not directly proportional to the case of DHF. The correlation of both variables shows that DHF case reaches its peak when the rainfall is in the mid-level 400 mm3. Because rainfall is not proved to affect the case of DHF future researchers are recommended to identify other variables namely temperature.
