Serious question: Has anyone seen an article or study about the microcephaly effects on pregnancy where the main population studied was not in brazil? I have yet to see a study that links it to microcephaly for anyone who has not been in brazil for a long time. I realize the mosquito isn't common, but brazil also does things like: "secretly spray tons and tons of pesticide on their populus", etc. Given these are all correlative studies, i'd love to see something from a country where there aren't a ton of possible other variables. (especially given zika has been around and even common forever and it's only now that this seems to be an issue) You know, before the tourism economies of all of these other countries are completely destroyed.

Yes, microcephaly from Zika has been detected in many south american countries. CDC supports the link, as does scientific consensus: http://www.cdc.gov/media/releases/2016/s0413-zika-microcephaly.html http://www.cdc.gov/media/releases/2016/s0413-zika-microcepha... It's the fat cats who don't want to move/postpone the Olympics most. They have the most to lose.

The article linked in the original post refers to a retrospective analysis in French Polynesia (the source of the virus in Brazil) that found a huge increase in Zika-induced microcephaly there as well.

Article said the virulent strain came from French Polynesia (aka Tahiti).

  French polynesia is not tahiti. Tahiti is one of the islands (rangiroa, moorea are other examples). Tahiti is the most populous, but if you read the study, it does not say tahiti. Most of the other islands are remarkably small. Note also that the methodology used in that study (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(16)00651-6/fulltext http://www.thelancet.com/journals/lancet/article/PIIS0140-67...) is a retrospective analysis of data that uses somewhat ... almost laughable assumptions- Modelling assumptions for estimation of risk of microcephaly associated with Zika virus infection: ... <this is just some of them> •All microcephaly cases in the study period have been identified •The birth rate is constant during the study period and can be estimated from official statistics •The number of Zika virus infections in a given week is proportional to the number of consultations for suspected infection in the same week Note the last one: They are estimating actual zika infections not from zika infections, but from consultations of people suspected to have zika and the percent who were later found to have zika. So how accurate is such a "suspicion based consultation"? By the end of the outbreak, public health officials had recorded 8750 suspected infections with Zika virus, of which 383 (4.4%) were confirmed in the laboratory. At this point, i'm going to suggest maybe their assumptions are not quite as strong as they think they are. ....
