GMO mosquitoes could be cause of Zika outbreak, critics say | Think outside the Box | Scoop.it
The latest contagious virus freaking out the globe, particularly women worried about birth defects, may have been caused by the presence of genetically-modified mosquitoes (GMMs) in Brazil.

With international health experts convening in Geneva to discuss the outbreak of and possible cures for the Zika virus, questions are being raised as to whether the GMMs are to blame.

In mid-2012, British biotech company Oxitec released the super bugs with the aim of reducing the overall mosquito population that spreads dengue fever, the Zika virus, and chikungunya in northeast Brazil.

At the time, concerns were raised about the release of GMMs without further studies into possible side effects.

"It's a very experimental approach which has not yet been successful and may cause more harm than good," Dr Helen Wallace, director of GeneWatch, told the Guardian in 2012.

The first cases of Zika in humans were reported in the south American country last May with up to 1.5 million now thought people affected by the virus, which Oxitec’s critics note is the same area where the GMMs were released.

Since the outbreak, there have been over 4,000 cases of babies born with microcephaly in Brazil, although various others causes can also be attributed to the rise.

The Aedes aegypti mosquito sub-species that carries both the Zika virus and dengue is the very type Oxitec targeted with its GMMs.

The aim of Oxitec's GM program was to release only male Aedes mosquitoes into the wild and they would in turn produce offspring with their virus carrying female counterparts.

This offspring would then die off before breeding age due to the GM coding in their genes, as long as the antibiotic tetracycline wasn't present, which would override the GM DNA.

Sounds like the plot of a Hollywood blockbuster.
