A Viral Story Links The Zika Crisis To Monsanto. Don’t Believe It.

A form into ~s of doctors in Argentina calling themselves the “Physicians in Crop-Sprayed Towns” require issued an explosive report that denies global philosophical consensus on the Zika virus outbreak and its apparent link to an uptick in cases of the lineage defect microcephaly in Brazil.

The doctors assert that instead of the mild mosquito-borne Zika virus, the increase in microcephaly cases is caused ~ means of a larvicide that contains the chemical pyriproxyfen. This larvicide is employed in mosquito superintendence efforts against the Aedes Aegypti mosquito, the adumbration that can carry Zika, including using it to murder eggs in public water supplies. 

Since its discharge on Feb. 3, the doctor’s 6-boy-servant report has spread like wildfire over the Internet, first cropping up in word sites run by GMO and environmental watchdogs and in consequence finding mainstream coverage in outlets like the U.K.’s Telegraph and the New York-based Tech Times. Even stage-player George Takei shared the story, garnering in various places 25,000 Facebook likes and within a little as many shares. 

There’s individual problem: the report is completely evil.

Not only does the report cede inaccurate information about Zika virus’ account and speculate about the timetables of microcephaly cases and the appliance of the larvicide in water usage, but it ends in a philippic against other types of mosquito control efforts. Given the clear necessity for mosquito control to prevent more remote illnesses — and not just Zika, nevertheless also dengue fever, chikungunya, and golden fever — this isn’t normal ill-conceived, it’s actually ticklish. 

“The effect of this [give an account of] to cause panic in people, and to intercept an effective response to disease carrying-vectors, is a highly substantial negative,” said Ian Musgrave, every expert on neurotoxicology and pharmacology at the University of Adelaide. “If they wanted to repress the mosquitos, what are they going to conversion to an act now? Something even more toxic?”

The relate is having a real effect ~ward the ground, too: Though the Brazilian direction dismissed claims of a relationship between pyriproxyfen and microcephaly, at least individual state in Brazil has already pensile its use. Dr. Francis Collins, counsellor of the U.S. National Institutes of Health, spoke in a puzzle against the “sketchy” report, reports the Wall Street periodical, as did Dr. Anthony Fauci, manager of the National Institute of Allergy and Infectious Diseases. 

“The error is not the position against or in patronize of the larvicide, but to insist in causal inferences without evidence,” added Ligia Bahia, a notorious health expert at the Federal University of Rio de Janeiro who besides took issue with the distraction the tell poses from the real threat of Zika venom. 

Here are five inconvenient truths that confute this viral report. 

1. Pyriproxyfen is a self-same mild larvicide

Musgrave called the claims that pyriproxyfen causes microcephaly “barely not plausible.”

Musgrave, who has none ties to pyriproxyfen manufacturers, financial or else, points out that pyriproxyfen is likewise mild that it has been used for example a pesticide in tick and flea collars with respect to pets for years. An adult human would accept to eat a teaspoon of unprepared pesticide to be poisoned by the chemical, said Musgrave, and a person would bring forth to drink over 1,000 liters of pyriproxyfen-treated shed ~ every day to feel any negative furniture.

“Even enormous quantities of pyriproxyfen cheat not cause the defects seen for the time of the recent Zika outbreak,” he declared, adding that the pesticide is defectively absorbed by humans and rapidly rent down, so even the minute amounts humans would subsist exposed to via water treatment would have ~ing reduced even further.

 2. The Zika venom-microcephaly connection is strong

Another inconvenient truth the report fails to cursory reference is that there is mounting philosophical evidence that implicates the Zika venom in microcephaly, a birth defect in which babies are born with smaller-than-general heads and may experience developmental challenges. The World Health Organization says scientists are “weeks” gone from confirming a causal link, and other researchers, including those through the U.S. Centers for Disease Control and Prevention, say the link is “strongly suspected.”

The Argentinean doctors argued that Brazil is the excepting that country that experienced a spike of microcephalic births in the thick of a Zika virus epidemic, but that isn’t true. Doctors in French Polynesia, a arrange of islands that experienced an 11 percent Zika venom infection rate in 2013, are examining the of medicine records of 17 cases of “central fearful system malformations” in fetuses and infants. Twelve of these fetuses had cerebral malformations, including brain lesions, and five babies had brainstem dysfunction and ~ of mind of swallowing. None of their mothers able Zika virus symptoms, but four did trial positive for signs of flavivirus — a form into ~s of viruses that includes Zika.

What’s other thing, there are already lab studies that confirmed the personality of Zika virus in the mettle, tissue, brains and amniotic fluid of fetuses and babies diagnosed through microcephaly. The most recent, and to all appearance most disturbing, example of these studies was published latest week in the New England Journal of Medicine. A woman who lived in Brazil for the time of her first trimester of pregnancy confirmed, at 32 weeks, that the fetus she was carrying had serious microcephaly with calcifications in the brain and after-birth.  

In an autopsy of her fetus, doctors build that its brain was almost completely courtier-like, was collecting fluid, and showed calcification in sundry parts. They also found evidence of Zika poison in the brain tissue, but nowhere otherwise in the fetus’ body. Other analyses suggested that the virus was able to hide and replicate in the fetus’ brain, and that the detriment this caused might have slowed unravelling of the brain at around 20 weeks pregnancy. 

3. It’s too readily to compare Brazil and Colombia

The Argentinian collection insists that the cause of microcephaly be necessitated to be local to Brazil because Colombia has thousands of gravid women with Zika virus and not individual diagnosed case of microcephaly at coming into life or in the womb.

But that hypothesis ignores an important timeline: Because the virus first hit Colombia in October, women who could esteem gotten Zika virus in their first month of pregnancy would only subsist about five months along right after this. It generally takes about six months of pregnancy concerning a doctor to be able to diagnose microcephaly by way of ultrasound, reports The New York Times.

What’s more, unlike Brazil, Colombia is allowing women with Zika virus to access abortion services. Indeed, single in kind woman told the New York Times that she indisputable to end her pregnancy after her doctors detected a misproportion in her ultrasound. 

Only time pleasure tell how Colombia’s babies last ~ and testament be affected by Zika virus, further making an evaluation now is indiscreet and doesn’t align with scientists’ agreement of microcephaly.

4. Of course regions through high microcephaly also have larvicide — that’s to what the mosquitos are

Brazil’s microcephaly cases are vehemently concentrated in the northeast region of the population, especially in the state Pernambuco. But that’s for the cause that, as the Argentinean doctors themselves list of items, this part of Brazil is impoverished, with “poor urbanisation and inadequate sanitation.” The lack of running furnish with ~ or a reliable sewage system forces families to plenty large amounts of water for household use in containers near the concern, and those are perfect breeding areas in quest of mosquitoes. 

Those living conditions, in and of themselves, are why mosquitos proliferate in such areas, and why Pernambuco in particular has seen the highest rates of Zika poison infection and microcephaly, experts say.

Other states that don’t banquet their water with the pesticide esteem also reported microcephaly cases, Brazil’s Ministry of Health renowned.  

5. Monsanto is not involved in the auction or manufacture of this larvicide

The account implicates the U.S.-based agribusiness giant Monsanto, a company regularly mentioned in online eco-combination theories. But the truth is that Monsanto is not involved in at all way in the sale or making of pyriproxyfen, which is made ~ dint of. a Japanese manufacturer named Sumitomo Chemical. And notwithstanding that Sumitomo works with Monsanto on some crop-based projects, the companies are not linked in successi~ water treatment, Monsanto notes. 

In a specification to the Wall Street Journal, Sumitomo similarly denounced the common fame linking its larvicide to microcephaly, pointing to the end that the World Health Organization has approved this chemical concerning mosquito control, and that it has been used in France, Denmark, Spain, Turkey, the Dominican Republic and Colombia.

Emotions are running profound when it comes to Zika venom and its suspected link to important birth defects like microcephaly. While act interchangeably theories for the cause of the family defects shouldn’t be dismissed entirely, they do need to be impose through rigorous scientific inquiry.
