# Alappuzha Residents Drastically Cut Mosquito Breeding Sites

A community initiative in Alappuzha, India, saw residents actively participate in identifying and eliminating mosquito breeding grounds. This led to a significant reduction in mosquito breeding sites across multiple wards.

## Key takeaways

- Residents of Alappuzha successfully reduced mosquito breeding sites by engaging in community-led control measures.
- A study conducted between 2016 and 2018 showed a significant decrease in breeding sites, with figures dropping from over 64% to 8.6% in one ward.
- Public health indicators like the container index and Breteau index showed substantial declines, indicating fewer breeding grounds for mosquitoes.
- The initiative utilized community structures, similar to Kerala's self-help networks, to organize awareness and clean-up efforts.

Residents of Alappuzha, a district known for its regular outbreaks of dengue, chikungunya, and leptospirosis, have successfully reduced mosquito breeding sites by engaging in community-led vector control. The initiative, which ran from November 2016 to October 2018, involved researchers from the ICMR-National Institute of Virology’s Kerala unit and TD Medical College, Alappuzha.

## What Happened

The program transformed residents into active participants in controlling mosquito populations. Before the study, a survey in the Vadackal ward found mosquito breeding sites in 64.2% of surveyed homes. Two years into the initiative, this figure dropped to 8.6%. Similarly, in Pazhaveedu ward, breeding sites decreased from 16.7% to 6%. The effort involved residents checking their homes and neighborhoods for standing water, a crucial step in preventing mosquito reproduction. This community-driven approach complemented existing efforts, which had previously struggled to achieve such reductions.

## Why It Matters

This project demonstrated that organized community involvement can be highly effective in controlling disease vectors. By empowering residents to identify and eliminate breeding grounds, the initiative led to substantial drops in key public health indicators. The container index, measuring water-holding containers with larvae, fell from 24.8 to 12.1 in Pazhaveedu, and from 37.7 to 18.1 in Vadackal. The Breteau index, which counts breeding containers per 100 houses, also saw significant decreases, dropping from 21.3 to 7.3 in Pazhaveedu and 47.7 to 8.6 in Vadackal.

## Background

The initiative was structured with community-level committees, inspired by Kerala's women-led self-help network, Kudumbashree. These committees organized awareness campaigns through posters, door-to-door visits, pamphlets, and a coordinated WhatsApp group. Residents also took initiative to clear uncollected garbage that was trapping water. This community waste management approach aligned with the town's existing decentralized waste management model.

## Key Facts

- In 2016, 64.2% of surveyed homes in Alappuzha's Vadackal ward had mosquito breeding sites.

- By 2018, this figure decreased to 8.6% in Vadackal.

- In Pazhaveedu ward, mosquito breeding sites fell from 16.7% to 6% during the study period.

- The container index in Pazhaveedu dropped from 24.8 to 12.1.

- The Breteau index in Vadackal decreased from 47.7 to 8.6.

- The study was led by researchers from the ICMR-National Institute of Virology’s Kerala unit and TD Medical College, Alappuzha.

- The initiative took place between November 2016 and October 2018.
