The microcephaly epidemic, which started in Brazil in 2015, was declared a Public Health Emergency of International Concern by WHO in 2016. Preliminary results of a case-control study investigating the association between microcephaly and Zika virus infection during pregnancy are reported. A case-control study was carried out in eight public hospitals in Recife, Brazil. Cases were neonates with microcephaly. Two controls (neonates without microcephaly), matched by expected date of delivery and area of residence, were selected for each case.
