Important update

After 3 years, the 'Applying Wolbachia to Eliminate Dengue' Randomised Controlled Trial conducted in Yogyakarta City shows incidence of dengue cases in intervention areas decreased by 77%  compared with untreated areas within the study site.

The World Mosquito Program is working in and around Yogyakarta to protect communities from mosquito-borne diseases like dengue, Zika, chikungunya and yellow fever.

Following encouraging results from our initial trials in Sleman and Bantul Districts in 2014, a large-scale efficacy study to evaluate the impact of our Wolbachia method on dengue transmission was conducted in Yogyakarta City. WMP worked closely with the government, health authorities, and local communities to undertake this work, which includes a quasi-experimental study and the first randomised controlled trial of Wolbachia for dengue control.

“This exciting result of the trial is a great success for the people of Yogyakarta. Indonesia has 7 million dengue cases every year. This trial result shows the significant impact the Wolbachia method can have in reducing dengue in urban populations.”
