Suppress the patient info so no one can find the water treatment cause ...
It was on FR in the past days the tie in to water treatment as in pesticide where the birth defects occured.

...The origin of the pesticide theory was, surprise surprise, a small physicians’ group that campaigns against pesticides. The group hasn’t done any epidemiology to demonstrate that people exposed to the pesticide are more likely to have babies with microcephaly; it has simply laid out an argument. The mainstream groups, looking at this problem holistically, have said there’s much better evidence that mosquitoes are hurting people than the evidence (and there’s no evidence, really) that the stuff killing mosquitoes is hurting people.
...This claim is not plausible. The pesticide in question is pyriproxyfen ... [t]he effect of pyriproxyfen on reproduction and fetal abnormalities is well studied in animals. In a variety of animal species even enormous quantities of pyriproxyfen do not cause the defects seen during the recent Zika outbreak. Pyriproxyfen is poorly absorbed by humans and rapidly broken down so even the minute amounts humans would be exposed to via water treatment would be reduced even further. As well, pyriproxyfen is relatively rapidly removed from the environment as well, so overall exposure will be low. The “Physicians in the Crop-Sprayed Villages” only evidence for the role of pyriproxyfen is that spraying began in 2014. While the evidence that Zika virus is responsible for the rise in microcephaly in Brazil is not conclusive, the role of pyriproxyfen is simply not plausible.
Another article was tying it into gm modified mosquitos we released awhile ago.
