Result of the three-year learn about, revealed within the New England Magazine of Drugs this week, discovered that infecting dengue-carrying mosquitoes with a innocuous micro organism known as Wolbachia ended in a 77 % drop in human circumstances.
Infections requiring hospitalization additionally fell by way of 86 % in Wolbachia-treated spaces of Yogyakarta, a town on Java island the place the experiment was once carried out, researchers stated.
The learn about was once carried out by way of the International Mosquito Program at Monash College in Australia and Indonesia’s Gadjah Mada college.

Signs in most cases come with frame aches, fever and nausea.
“That is the end result we now have been looking ahead to,” stated International Mosquito Program director Scott O’Neill.
“We have now proof our Wolbachia approach is secure, sustainable and dramatically reduces occurrence of dengue.
