Abstract

Oviposition trap index (OI) and adult productivity index in the ovitrap (OviP) were determined to establish the Aedes situation in selected public elementary schools (ES) in the National Capital Region (NCR). A maximum number of 32 ovitraps were placed at 1 ovitrap/classroom in the identified classrooms of the 29 selected ES study sites. OI and OviP values were then used to classify schools according to critical thresholds. Schools with OI≥10% and OviP≥5% were considered at high-risk to dengue transmission. Results showed that from April to May (dry hot months), 35% of the schools had OI≥10% and OviP≥5% while 50% had OI≥10% and OviP≥5% (medium-risk). During the wet months of June to November, schools at high risk increased to 79% but decreased to 69% in December to February (dry cold months). This further decreased to 55% in the month of March. The average OI and OviP of the selected elementary schools for each season were higher than the critical thresholds. These initial findings will be correlated with dengue transmission cases and weather data towards the development of a predictive model.
