As parts of Karnataka continue to see heavy rains due to weather systems forming in the Bay of Bengal, the state has seen a sharp rise in the number of dengue infections between September and November this year, causing the state Health Department searching for ways to mitigate the spread of the disease.
Between September 15 and November 17, Karnataka saw a sudden spurt of 84% in the number of dengue cases. The state had recorded 2,987 dengue cases till September 2021.

Incessant rains, water stagnation points, pits, and garbage dumps have been the cause for mosquitoes to breed, causing dengue, according to Health Department officials.
