Question:
Vector index used in quantitative assessment of malaria is:
Vector index used in quantitative assessment of malaria is:
Show Hint
HBI = How many "Bites" the mosquitoes take from "Humans."
Updated On: May 25, 2026
- Slide Positivity Rate
- Annual Parasite Incidence
- Human Blood Index
- Annual Blood Examination Rate (ABER)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Epidemiological indices for malaria are divided into parasitic (human host) and entomological (mosquito vector) indices.
Step 2: Meaning
A vector index specifically measures aspects related to the mosquito population's behavior or density.
Step 3: Analysis
API, SPR, and ABER are parasitic indices measured in human populations. The Human Blood Index (HBI) measures the proportion of female mosquitoes that have fed on human blood.
Step 4: Conclusion
HBI is a critical vector index used to assess the intensity of malaria transmission. Final Answer: (C)
