I hate the expression “perfect storm,” but here is one: The mosquito engineered to wipe out dengue fever, by being released where tetracycline is present in animal feed, breeds without the self-destruct function, thereby facilitating the spread of Zika virus. Or maybe the tetracycline–inserted into genes as a marker–is itself part of the genetic engineering process (though the article doesn’t say so).http://theantimedia.org/zika-outbreak-epicenter-in-same-area-where-gm-mosquitoes-were-released-in-2015/
