Vector Surveillance.pptx
- 2. Vector surveillance: Used to determine changes in the geographic distribution and density of the vector Evaluate control programs Obtain relative measurements of the vector population over time and facilitate appropriate and timely decisions regarding interventions Indentify areas of high-density infestation
- 3. Conventional Indices: Conventional indices are used to monitor the vector populations for dengue virus transmission. House index (HI) Container index (CI) Breteau index (BI) Pupal Index (PI) Used for the surveillance of immature stages of the mosquito
- 4. House Index (HI): the percentage of houses infested with larvae or pupae HI = Number of infested houses X 100 Number of inspected houses
- 5. Container Index (CI): the percentage of water-holding containers infested with larvae or pupae CI = Number of infested containers X 100 Number of inspected containers
- 6. Breteau Index (BI): The number of positive container per 100 houses inspected BI = Number of infested containers X 100 Number of inspected houses
- 7. Pupal Index (PI): The number of pupae per 100 houses PI = Number of pupae X 100 Number of inspected houses
