I am referring, of course, to the Zika virus, which is currently exploding in the tropics, and is suspected of being connected to microcephaly and low brain development in infants born to infected women, and also cases of the neurological disease Guillain-Barré syndrome. (Nota bene: these connections are still tentative, and are being studied. The evidence thus far indicates possible links, but establishing causation and finding an underlying mechanism in either case have yet to be accomplished.)
Of course, a viral disease carried by mosquitoes, with uncertain and possibly devastating consequences for the victims through an unknown mechanism, opens the door for wild speculation. And the conspiracy-minded amongst us have certainly been quick to rise to the occasion.
First, we have the claim that Zika was caused by the release of genetically-modified mosquitoes by Oxitec Inc., a biotechnology firm -- in some versions of the story, caused deliberately for the purposes of population control. And since no conspiracy is complete without a powerful rich guy controlling the whole thing, the originator of this evil master plan is...
... none other than Bill Gates.
So, the idea is that under Gates's funding and direction, Oxitec genetically engineered the virus, then genetically engineered mosquitoes to carry it, and released them in Brazil. Since then, they (and the virus) have been spreading north rapidly.
My question is: why would Bill Gates do this, given that if the population of the Earth crashes, there will be far fewer people around to purchase updates to Windows every six weeks? He doesn't really seem to have a lot to gain by spawning a pandemic. And as for the conspiracy theorists, they're not really clear about this. The upshot is, "Mwa ha ha ha ha ha ha ha, that's why."

But the conspiracy silliness doesn't end there. Jon Rappoport, whose dubiously sane pronouncements have been featured in Skeptophilia before, has come up with something even goofier. In his blog post "Zika Hoax: Five Things That Will Happen Next," we hear that there is no connection between Zika and microcephaly (which, of course, could turn out to be true; as I mentioned earlier, scientists are still investigating the point). Then, however, he runs right off the cliff, predicting that researchers will develop a vaccine for Zika, but that the vaccine and the virus will turn out to be "weaponized biowar [agents]."
Because if you've launched a biological warfare virus, the first thing you'd do is to come up with a vaccine that's also for biological warfare. And somehow, Zika is both a hoax and an evil biological weapon at the same time.
How evil can you get? Cf. "Mwa ha ha ha ha ha ha ha ha ha."
Of course, the major problem with all of this foolishness is that the basis of the conspiracy is that the release of the GM mosquitoes coincides, both in time and place, with the outbreak. And this turns out to be false. As Wilcox writes:
The epicenter of the outbreak and the release clearly don’t line up—the epicenter is on the coast rather than inland where the map points. Furthermore, the first confirmed cases weren’t reported in that area, but in the town of Camaçari, Bahia, which is—unsurprisingly—on the coast and several hundred kilometers from the release site indicated.
But perhaps more importantly, the location on the map isn’t where the mosquitoes were released. That map points to Juazeiro de Norte, Ceará, which is a solid 300 km away from Juazeiro, Bahia—the actual site of the mosquito trial. That location is even more on the edge of the Zika-affected area.On the other hand, think about it; it makes sense that they'd release the GM mosquitoes near where the outbreaks occurred. Since the whole idea is to control Zika in Brazil, it wouldn't make much sense to release the mosquitoes in, say, Greenland.
But that sort of logic never seems to appeal as much as fact-free and panic-stricken shouting, for some reason.
In any case, bottom line: Zika isn't genetically engineered, isn't new, and isn't being spread by GM super-mosquitoes because of some obscure plot by Bill Gates. I'd be much obliged if people would stop spreading this nonsense around, because it's got to be annoying to the scientists who are working on the real problem that Zika represents. Thank you.
