Does Zika Cause Microcephaly?

The world is now in full blown panic regarding the Zika virus, and its link to microcephaly, a rare disorder that causes newborns to develop abnormally small skulls and brains.  Just today, there appeared this article in the BBC, and this article in the Daily Beast.

But in Brazil and Argentina, there is a growing controversy over whether Zika is the cause of the birth defect.  Doctor's groups in both countries are claiming that the real cause of the birth defects is not Zika, but a chemical, pyriproxyfen, used in mosquito eradication programs.

GM Watch first reported on this last Wednesday, with a link to this report from an Argentine doctor's group.  On Sunday, the southernmost state of Brazil, Rio Grande do Sul, suspended the use of the pesticide.  Here is an article in Britain's Telegraph newspaper from yesterday, stating that the national government disagrees and insists that Zika is the cause of the birth defects.

As the doctor's group points out, Zika has been around for a long time.  The pesticide has not.  It's use in Brazil only began in 2014.

Why are there no reports about this in the American Press?  Maybe this headline will give you a clue:

Report says Monsanto-linked pesticide is to blame for microcephaly outbreak - not Zika

Stay tuned.
