During a dengue outbreak investigation, entomological survey data are being interpreted. According to standard teaching, a Breteau Index above which value indicates that an area is at risk of an epidemic of dengue?

• A Above 1
• B Above 20
• C Above 10
• D Above 5 ✓

Explanation

The Breteau Index expresses the number of positive containers per 100 houses and links vector density with container productivity. Standard teaching holds that a House Index above 10 percent, a Container Index above 10 percent and a Breteau Index above 5 signify an area at risk of a dengue outbreak. Despite the name, the House Index counts houses and not individual household members, and neither 1 nor 20 is the accepted threshold.
