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. ....
