Brazilian president Dilma Rousseff went so far as to declare war on Aedes aegypti, the mosquito that transmits Zika.
Several technological approaches may start to look appealing to eliminate mosquitos.
1. Cell phones are useful because they record the movements of their owners. That data can be used to track disease hot spots and predict where they may flare up next. The technique has already been employed in Africa in the battle against malaria and in Pakistan against dengue fever—both mosquito-borne diseases like Zika.
2. Genetically modified mosquitoes could also have a role to play. Successful tests in the Cayman Islands and Brazil have shown that the introduction of modified male mosquitoes can cause local populations to crash. But these tests, conducted by the British firm Oxitec, have so far been on the scale of a few neighborhoods. Ramping up the process to cover all of Brazil would require a huge logistical effort to grow
3. Then there is the gene drive. This newly developed technology involves inserting genes into an organism in such a way that a trait spreads throughout a whole population. In theory, a gene drive could be created that prevents mosquitoes from incubating Zika virus—or destroys the entire species of A. aegypti. A gene drive has been created that prevents mosquitoes from harboring the malaria parasite. But some researchers are understandably concerned about intentionally messing with natural selection. Once a drive is released into a wild population, there is no turning back, and there is no telling what sort of side effects it might have.
Ultimately, it is unlikely that any one method will stop Zika in its tracks. Winning this war is possible—it has been done before.
Nextbigfuture had advocated a few days ago using gene drive to kill the Zika mosquitos.
In July, 2015 geneticists showed that one gene drive system was almost 100% effective in spreading a mutated pigmentation gene through a population of lab fruit flies, fueling fears about the power of gene drive.
