The media said that the mosquito borne Zika virus is likely causing microcephaly as well as dozens of other illnesses. They also claimed that insecticides were not related to the development disorder. They seem to have been wrong on both cases.

Since December 2015 U.S. media ran a panic campaign round the Zika virus. That virus was said to cause many bad things including microcephaly, a development distortion of the head of unborn babies, if the mother was infected with Zika during pregnancy.

After looking into the issue and the available data I concluded that: The Zika Virus Is Harmless:

The virus is long known, harmless and the main current scare, that the virus damages unborn children, is based on uncorroborated and likely false information.



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.

As this is all well known or easy to find out why do the media create this sensation?

By March the media attributed all known human ills to Zika though every headline doing so included a telltale caveat may. I mocked these in Reading About Zika May Hurt Your Brain

[E]ven while Zika is known to be less harmful than an average flue, one headline after the other tries to create the impression that it is some really awful, new bug that may be responsible for about any ailment. That it may spread like wildfire and may have other terrible consequences. May, as in ‘the sky may fall’, is indeed the most operative word here.

There followed a collection of 35 recent “Zika may cause …” headlines.

Meanwhile doctors 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 facts are facts and as these come to the fore the embarrassed media will now likely stay silent.

The New England Complex Systems Institute in Cambridge just published a new study that falsifies the assumed link between Zika and microcephaly. Science Daily reports:

In Brazil, the microcephaly rate soared with more than 1,500 confirmed cases. But in Colombia, a recent study of nearly 12,000 pregnant women infected with Zika found zero microcephaly cases. If Zika is to blame for microcephaly, where are the missing cases? Perhaps there is another reason for the epidemic in Brazil.

Who could have known?

Well, maybe those doctors on the ground in Brazil knew what they were talking about. The scientist 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.

Sumitomo sold a poison in Brazil which was supposed to prevent the spread of mosquito borne Zika virus by hindering the development of mosquito larvae. Suddenly cases of the human development disorder microcephaly occurred. The company knew that their insecticide could cause birth defects in mammals. But they continued to blame the Zika virus which then increased demand for their poison to “prevent” the further spread of that false Zika cause.

Some enterprising lawyers might find enough material in this case to hold the company responsible for the suffering it probably caused for many families in Brazil.

But the media should also be held responsible. First for spreading a false panic and for attributing all kinds of nonsense to a harmless flue virus. They should also be held responsible for not diligently investigating the possibly human-effected cause of the development disorder. The one that now seems to turn out to be the real culprit.
