Malaysia To Genetically Modify Male Mosquito To Curb Dengue

Dengue fever, spread by the Aedes aegypti mosquito is common in Asia and Latin America. Symptoms include high fever, joint pains and nausea, but in severe cases, it can lead to internal bleeding, liver enlargement, circulatory shutdown and death. There is no known cure or vaccine.

In Malaysia, the number of dengue linked deaths totaled 117 between January and early October, a 65 percent surge from last year, according to Health Ministry statistics. Dengue infections overall increased 17 percent from last year to more than 37,000 cases.

Efforts to urge Malaysians to keep neighborhoods clean and destroy stagnant sources of water, which are mosquito breeding grounds have failed and innovative ways are needed to combat dengue, Malaysian Prime Minister Najib Razak had said.

Malaysian scientists say laboratory test trials have made them optimistic. “It is a pilot project, and hopefully it will work,” Najib Razak told reporter on the sidelines of a World Health Organization (WHO) conference in Malaysia.

Malaysia could be the first country in Asia to use genetically modified mosquitoes to battle a rise in dengue fever, government authorities have said.

The program calls for genetically engineered male mosquitoes to be released into the wild that would mate with females and produce offspring with shorter lives, thus curbing the dengue mosquitoes’ population.

Malaysian authorities plan to release between 2,000 to 3,000 genetically modified mosquitoes in two areas, according to Lim Chua Ling, a health ministry official.

The plan which cannot be undertaken without Cabinet approval, would be the first such release of genetically modified mosquitoes in Asia to combat dengue.

WHO Western Pacific region has welcomed Malaysia’s efforts to step up the fight against dengue, but also cautioned that care must be taken in introducing a new species to the environment.
