The data and results are also available online, more or less updated regularly, here. As of 28th March this year, there were 56 live-born infants with birth defects and 7 pregnancy losses with birth defects out of 1,311 completed pregnancies reported to the U.S. Zika Pregnancy Registry.

How do we square the different conflicting results? Despite its inherent biases (i.e. pregnant women with symptoms are more likely to be tested than pregnant women without symptoms, and the Zika serological test – unless a plaque reduction neutralization test is performed – is notoriously nonspecific), the U.S. Zika Pregnancy Registry represents the best collected large dataset on Zika-infected pregnant women to date. The results are of significant concern and we will have to wait for local results from our much smaller birth cohort to be released, even as efforts are made to contain the latest Zika clusters.
