Prospect of latest method to fight dengue

Trial of an interesting method to fight dengue in the Florida Keys of the USA is going to be approved soon. According to a report in this daily, the trial planned by mosquito control officials of the tourist town Key West and a British Company named Oxitec would release non-biting male mosquitoes that have been genetically modified to pass along birth defect that kill their progeny before reaching maturity. The idea is that the genetically modified mosquitoes will mate with wild Aedes aegypti female mosquitoes (because they can spread dengue fever) and their progeny will die before reproducing.
So, after a few generations, the researchers expect, Aedes aegypti population would die off, reducing the dengue fever risk without using pesticides, at a relatively low cost. However, regarding impact on the ecosystem after implementing this method, researchers say that the modified genes will disappear from the environment after the mosquitoes carrying it die, resulting in no permanent change to the wild mosquito population.
Anyway, the above mentioned method might be an effective tool for Bangladesh to fight dengue as this disease is one of the health concerns here. It may be mentioned that there is no reliable vaccine for dengue fever. So, we hope authorities concerned would think of implementing this latest and cost-effective method after studying its impact on the food chain of other animals.
