I don’t buy that the CDC and WHO that ZIka is for sure to blame for microcephaly. Many questions left unanswered and the correlation appears to be more due to the amount of media coverage connecting the two.

Here’s a recent article expressing some doubts.

Very glad you posted this. Zika has been around for decades (most likely much longer). Never previously being linked to Microcephaly. Brazil, the epicenter of microcephaly cases, has had 2 interested thing occur in the last couple years...

1. Mandating vaccinations of pregnant women
2. Genetically engineering mosquitoes

Either of these seem very dangerous compared to the Zika Virus itself...

Thank you for the link. I have been doubtful about a connection between Zika and microcephaly, for a number of reasons. For example, if a virus is a causative agent, then geography should make no difference in the incidence of the observed effect. But Zika is only correlated with microcephaly in Brazil, and correlation is not causation. So I might suspect that there is some factor in common with the emergence of Zika and the microcephaly.

From the linked article: "One possibility that has been raised is the pesticide pyriproxyfen, which is applied to drinking water in some parts of Brazil to kill the larvae of the mosquitos that transmit Zika. Pyriproxyfen is an analogue for insect juvenile hormone which is cross reactive with retinoic acid, which is known to cause microcephaly."

This fits exactly with my suspicion that the microcephaly is caused by an environmental factor. In this case, the environmental factor would be the pesticide used to control the mosquitoes. And because Zika does not happen without the mosquito vector, and the pesticide is not used unless there are mosquitoes, the microcephaly is only observed in areas where that pesticide is being used--and the cause was mistakenly blamed as Zika.
