Dengue has been and is still a serious public health problem in Iligan City, Lanao del Norte. The increase of the number of dengue cases has been attributed to climate change; however, contradicting reports show uncertain relationships between dengue and climatic factors. This study showed the relationship between climatic factors with dengue fever (DF) and dengue hemorrhagic fever (DHF) incidence reported in Iligan City from 2005-2009. The climatic factors include maximum temperature, minimum temperature, rainfall and relative humidity. Pearson's correlation was used to explore the primary association between the DF and DHF incidences and the preceded climatic factors. Multiple regression analysis was also used to fit the statistical model. The result showed that the total number of dengue cases (both DF and DHF) used as the dependent variable gave a predicted regression model of Y (dengue incidence) = - .307 (temp max) + .375 (temp min) + .024 (rainfall) - .323 (relative humidity) which means that these constants have a significant correlation to dengue cases suggesting that an increase or decrease of its values could affect the number of dengue cases.
