“While measures can be directly implemented by the state Government for open water bodies which serve as breeding ground for Anopheles mosquitoes, community participation is needed to fight the menace of Aedes mosquito, which breed in clear water within homes,” Bhatt said, adding that to combat the threat, the department was preparing a Container Index (CI), House Index (HI) and Bratou Index (BI) to identify areas needing intervention.

“For preparing such indices, our workers are carrying out door to door surveys and checking out containers and houses,” said a senior health official, adding that apart from preparing the CI and HI, data was also being compiled to identify the number of containers breeding mosquitoes per one hundred houses.
