Abstract

A study was conducted in Muntinlupa City, a fast-expanding city in southern Metro Manila, to understand the implications of different ecological, biological, and social determinants affecting vector pupal indices and dengue transmission risk in the area. Selected barangays (administrative ‘villages’) were categorized as either high or low dengue incidence areas based on the reported dengue incidence of the area at the time of study. These communities were further classified into either high or low human population density areas (HPD and LPD clusters) to determine the influence of socio-economic factors on vector density and disease risk. Study findings found HPD and LPD clusters with low dengue incidence were generally more knowledgeable about dengue and had more access to sources of information about the disease and prevention. However, communities’ knowledge on dengue does not necessarily translate to a reduction of vector density in their areas, as indicated by the statistical test performed in the study. Statistical analyses also revealed that some of the government interventions and community/household-based prevention practices were shown to be effective for dengue control to reduce infection risk, but require more frequent monitoring to maintain sustainable control of the vector population. Moreover, the percentage of green areas in the surveyed clusters has an effect on the vector density of the study. An overall analysis using chi-square showed that there is a correlation between pupal density, human population density, and the number of dengue cases.
