Malaysia said Monday its dengue fever death rate spiralled 53 percent this year, but backed away from a controversial trial of releasing genetically modified mosquitoes to wipe out the disease.
"There was a major rise in deaths due to dengue fever, with 107 deaths so far this year compared to 70 deaths for the same period last year," said deputy premier Muhyiddin Yassin.
Muhyiddin said the majority of the deaths could have been avoided, and urged the public to take action to eradicate the Aedes aegypti mosquitoes -- which spread dengue -- from their homes and workplaces.
"We have identified 19 hotspots throughout the country where the disease is prevalent, and action is being taken to tackle the situation in these areas," he said.
However, Muhyiddin was cool on a plan to release genetically modified mosquitoes designed to combat dengue fever, in a proposed landmark field trial that has come in for criticism from environmentalists.
In the first experiment of its kind in Asia, 2,000-3,000 male Aedes aegypti mosquitoes were to be released in two Malaysian states in October or November if the plan had won government support.
The insects in the study have been engineered so that their offspring quickly die, curbing the growth of the population in a technique researchers hope could eventually eradicate the dengue mosquito altogether.
Females of the Aedes species are responsible for spreading dengue fever.
