A Special Breed Of Mosquito Proved To Be Effective In Reducing Dengue Cases

Dengue fever is a mosquito-borne viral disease that occurs predominantly in tropical and subtropical areas. This fatal disease is caused by bites of the Aedes mosquito. Every year millions of people get affected by it.

Few researchers were working in a direction to find a protective measure to control Dengue’s spread. A team has conducted trials in Yogyakarta where mosquitoes that are infected with bacteria named Wolbachia have been released in the city. The experiment registered 77% declination in the infection cases and an 86% reduction in hospitalizations. The New England Journal of Medicine has published this case study.


The bacterium in the modified mosquito will control their reproduction and mosquitoes will have only Wolbachia-infected offspring. Hence, the new insect population will not transmit viruses such as dengue, yellow fever and Zika.

Florida, Australia and Singapore have conducted similar mosquito studies.

Adi Utarini, lead investigator and professor at the University of Gadjah Mada said, “It’s a great success for the people of Yogyakarta, Indonesia as the country has more than 7 million dengue cases every year. We are thinking there is a possible future where residents of Indonesian cities can live free of dengue.”

Owing to the positive results of the experiment, modified mosquitoes are planned to be released outside the district, said Dr Katie Anders of the World Mosquito Program, which helped sponsor the trial.
