Multi-site field study

From July 2022, NEA will be expanding releases of male Wolbachia-carrying Aedes aegypti mosquitoes (Wolbachia-Aedes) to cover an additional 1,400 HDB blocks and 154,606 households. This will be 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.
