Incidence of Dengue in Ozamiz City, Philippines

The incidence of dengue has become a serious health concern in many areas around the world. The increasing number of dengue cases are said to be the result of rapid population growth and climate change. This study assessed the incidence of dengue in Ozamiz City, Philippines. It also determined the relationship of climatic factors on dengue incidence reported in the area. Documentary analysis was done in seven hospitals to identify the incidence of dengue in the city. Pearson’s correlation was used to determine the association between climatic factors and dengue incidence. Multiple regression analysis was also used as a statistical model.  A total of 1,908 dengue cases were reported from January 2008 to September 2013. Majority of the patients belonged to the age group of 1-10 years. Maximum number of cases was seen in 2010 (398 cases) which was highest in the month of January (215 cases). Out of the total 1,908 cases, 821 (43.03%) were dengue hemorrhagic fever, 781 (40.93%) were dengue fever and 306 (16.04%) were dengue shock syndrome. Among the 51 Barangays in the City, Barangay Aguada has the highest number of 186 cases (9.75%). Of all climatic factors, only relative humidity has a positive correlation with dengue incidence. Vector control and education campaign needs should be assessed as these factors may significantly influence the occurrence of dengue in the city. Strategic plans and measures for dengue prevention need to be implemented targeting young population.
