Multi-site field study
In July 2022, NEA expanded releases of male Wolbachia-carrying Aedes aegypti mosquitoes (Wolbachia-Aedes) to cover an additional 1,400 HDB blocks and 154,606 households. This is part of a 2-year study to determine the impact of the Wolbachia technology on reducing dengue cases.
The sites selected were based on a set of criteria:
- historical dengue risk level (2016 to 2020)
- Aedes aegypti population
- size and landscape of the area
- NEA’s capacity for producing and releasing male Wolbachia-Aedes mosquitoes.
