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.

The Indonesian Ministry of Health (MoH) has evaluated the results of Wolbachia releases in Yogyakarta and decided there was enough evidence to scale up WMP’s Wolbachia method to help protect millions more people in Indonesia. The gold-standard randomised controlled trial showed a 77% reduction in dengue cases and 86% reduction in dengue hospitalisations in Wolbachia-treated areas compared with untreated areas.

“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.”
