Suara.com – New hope for handling dengue fever dengue alias DBD in Indonesia comes from modification mosquito. What does it mean?
Research from Gadjah Mada University (UGM) has shown that infecting mosquitoes with bacteria can reduce cases of dengue fever by up to 77 percent. This is because bacterial infection can stop mosquitoes from transmitting the deadly dengue virus in Indonesia.
Researchers modified the mosquitoes and allowed them to breed for three years. Then the results found that dengue cases were reduced by up to 77 percent in the modified mosquito area, the researchers wrote in a research report in the New England Journal of Medicine.
Mosquitoes that are infected with the bacteria are called Wolbachia. Researchers explained that the bacterial infection not only interferes with the ability of the virus to live in the insect’s body, but also controls reproduction so that mosquitoes only have offspring infected with Wolbachia.

The result is a growing population of insects that do not transmit viruses such as dengue fever, yellow fever, and Zika.
The study involved more than 8,000 people, about half of whom live in areas where the modified Aedes aegypti mosquito is allowed to live and breed.
“The protective efficacy of the intervention was 77.1 percent. There are very few randomized intervention trials against dengue fever mosquitoes,” said Dr. Katie Anders of the World Mosquito Program, which helped sponsor the trial, said in a statement.
“The results of this trial from Yogyakarta show convincingly that Wolbachia works to reduce the incidence of DHF and DHF hospitalizations,” he added.
Mosquito research results have also been tested in the Florida Keys and Australia. As many as 400 million people become infected with dengue fever each year, according to the United States Centers for Disease Control and Prevention.
