Q&A: Mosquito breeding trial raises hopes of defeating dengue


Public health messaging for dengue control often encourages the clean-up of mosquito breeding sites. But a novel method that researchers at the World Mosquito Program have introduced to several communities over the past eight years directly counters that concept. Instead of killing mosquitoes, they breed mosquitoes injected with Wolbachia bacteria and release them to communities that have been affected by dengue. Evidence from different countries where the method has been used showed large reductions in dengue transmissions. The method is not about suppressing the mosquito population, but about transforming them to a population that carries Wolbachia.
