Bacteria makes a dengue ‘stop sign’ in mosquitoes

Infecting mosquitoes with Wolbachia bacteria has reduced the insect’s ability to spread dengue fever by 77% in a trial, scientists have said.

The Wolbachia bacteria persists in the mosquito population meaning the intervention only has to be done once to give a community protection from dengue for many years, the lead researcher on the project, Prof Cameron Simmons, told BBC World News.
