The Zika Virus Is Harmless - It Does Not Cause Birth Defects - We Told You So

After nearly a year of causing hysteria, mass travel cancellations and unnecessary abortions it finally daunts to "journalists" and "experts"  that the Zika virus is harmless. It can cause a very minor flue - two days of a low fever and uncomfortable feeling for a quarter of those infected - that is all. It does not cause, as was claimed by sensationalists in the media and various self-serving "scientists", birth defects like microcephaly.


We told you so.


In February we wrote: The Zika Virus Is Harmless - Who Then Benefits From This Media Panic?.


The piece refereed to a Congressional Research Service report and various sound scientific papers. It concluded:



There is absolutely no sane reason for the scary headlines and the panic they cause.


The virus is harmless. It is possible, but seems for now very unlikely, that it affects some unborn children. There is absolutely no reason to be concerned about it.



The artificial media panic continued and huge amounts of money were poured into dangerous insecticides to kill mosquitoes (and important pollinators) that did not do any harm. Indeed, generous use of some of these insecticides likely were the very cause of a blip in microencephaly cases in northeastern Brazil.

In March we wrote: Reading About Zika May Hurt Your Brain.


We listed 35 "news" headlines about potential catastrophes related to a Zika epidemic. The common factor - all those headlines included the miraculous little word may. The pieces were pure speculations though some quoted this or that "expert" who was hunting for new research funds or lobbying for some pharmaceutical or pesticide conglomerate.


In June we added: Zika Virus Does Not Cause Birth Defects - Fighting It Probably Does.


New serious research found what some people in Brazil had suspected from the very start of the small and strictly locally limited jump in microencephaly cases in Brazil:



[D]octors in the Zika affected areas in Brazil pointed out that the real cause of somewhat increased microcephaly in the region was probably the insecticide pyriproxyfen, used to kill mosquito larvae in drinking water:



The Brazilian doctors noted that the areas of northeast Brazil that had witnessed the greatest number of microcephaly cases match with areas where pyriproxyfen is added to drinking water in an effort to combat Zika-carrying mosquitoes. Pyriproxyfen is reported to cause malformations in mosquito larvae, and has been added to drinking water in the region for the past 18 months.



Pyriproxyfen is produced by a Sumitomo Chemical - an important Japanese poison giant. It was therefore unsurprising that the New York Times and others called the doctors report a "conspiracy theory" and trotted out some "experts" to debunk it.
...
But [s]cientist at the New England Complex Systems Institute also researched the pyriproxyfen thesis. They found:



Pyriproxifen is an analog of juvenile hormone, which corresponds in mammals to regulatory molecules including retinoic acid, a vitamin A metabolite, with which it has cross-reactivity and whose application during development causes microcephaly.
...
[T]ests of pyriproxyfen by the manufacturer, Sumitomo, widely quoted as giving no evidence for developmental toxicity, actually found some evidence for such an effect, including low brain mass and arhinencephaly—incomplete formation of the anterior cerebral hemispheres—in rat pups. Finally, the pyriproxyfen use in Brazil is unprecedented—it has never before been applied to a water supply on such a scale.
...
Given this combination of information we strongly recommend that the use of pyriproxyfen in Brazil be suspended pending further investigation.




Today the Washington Post finally admits that the Zika virus does not cause birth defects:



[T]o the great bewilderment of scientists, the epidemic has not produced the wave of fetal deformities so widely feared when the images of misshapen infants first emerged from Brazil.


Instead, Zika has left a puzzling and distinctly uneven pattern of damage across the Americas. According to the latest U.N. figures, of the 2,175 babies born in the past year with undersize heads or other congenital neurological damage linked to Zika, more than 75 percent have been clustered in a single region: northeastern Brazil.



The localities where the flue virus occurred outside of a small area in Brazil saw no increase in birth defect numbers. The number of (naturally occurring) microcephality cases stayed constant despite a large increase in (harmless) Zika virus infections. The numbers in Brazil also turned out to be partially inflated because of a lack of standard diagnosis criteria and unreliable statistics. A factor we had pointed to in our very first piece.


The WaPo piece today muses about several "possible" causes for the local increase in cases in northeastern Brazil that indeed happened. It quotes some of the very "experts", like from the pharmaceutical industry influenced CDC, that were wrong on the issue since the first panic headline. It strenuously avoids to even mention the most likely cause - the excessive local use of an insecticide that is supposed to cause birth defects - in developing mosquitoes. Thus the reporting is still void of journalistic ethics and irresponsible in its conclusions.


It did not take much effort to get this right. An hour or two of skimming through publicly available sources of good standing, some basic higher education and sound reasoning was enough. But instead of doing such basic inquiries "journalists" and media "served" panic and speculations by biased "experts". Keep this story in mind for the next sensationalist onslaught of panic headline. There surely will be some "interests" behind those; just don"t expect unbiased facts and basic logic reasoning.
