Abstract

Dengue fever is the most widespread mosquito-borne viral disease globally. Transmission of dengue virus is essentially influenced by climatic factors and there is much concern as to whether climate change would spread the disease to areas currently unaffected. The main aim of this study was to analyze the incidence of dengue virus in Cagayan de Oro City and to determine the geographic and ecological factors associated with dengue disease. Dengue fever incidence of 42 barangays, monthly rainfall, annual temperature, precipitation, age and gender distribution of dengue fever cases were determined from 2014-2016. Areas in Cagayan de Oro with incidence of dengue were identified based on ecological and demographic factors. The data showed that rainfall, temperature, age, gender and the actual location of respondents affected by dengue have higher influence on dengue incidences. Population and house density has revealed that dengue generally occurred in areas with high population, thus contribute to high-risk area such as neighboring community and households. Further studies on the development projection map on the basis of geo-tagging of the actual location of respondents affecting dengue virus and the flying distance of mosquito are highly recommended to significantly continue monitoring and surveillance of the affected barangays. The incidence of dengue is continues to be emerging over the next few years, thus requires continuous monitoring and surveillance especially in barangays in Cagayan de Oro with high dengue incidence.
