May 29, Colombo (LNW): Health Entomology Officer’s Association President Najith Sumanasena yesterday (28th) warned of a potential dengue epidemic as the Breteau index, which measures the density of dengue larvae, has surged to 25.
Sumanasena highlighted that the increased mosquito density could result in a dengue epidemic within the next six weeks, with some areas reporting Breteau indices as high as 30 to 40. According to the World Health Organization, the Breteau index should remain below 5 to prevent outbreaks.
He attributed the rise in the index to several factors, including the festival season, school examinations, and temple festivals, which have led to a lapse in dengue awareness and environmental cleanliness.
The recent rains have caused water accumulation, promoting mosquito breeding. Sumanasena emphasized that maintaining a clean environment to prevent water stagnation can significantly reduce the risk of dengue.
