The Stegomyia indices used in dengue surveillance include the Container Index, Breteau Index, and House Index. The Breteau Index is defined as the number of:

• A Positive houses per 100 houses inspected
• B Positive containers per 100 houses inspected ✓
• C Infested containers per total containers inspected
• D Pupae per house inspected

Explanation

Breteau Index = (Number of positive containers / 100 houses inspected). Container Index = (Positive containers / Total containers inspected) × 100. House Index = (Positive houses / Houses inspected) × 100. The Breteau Index is considered the most useful single measure for dengue risk assessment as it takes into account both the number of positive containers and houses surveyed. Threshold for epidemic risk is Breteau Index >50.
