Ahead of Print -Projecting Month of Birth for At-Risk Infants after Zika Virus Disease Outbreaks - Volume 22, Number 5—May 2016 - Emerging Infectious Disease journal - CDC

The marked increase in infants born with microcephaly in Brazil after a 2015 outbreak of Zika virus (ZIKAV) disease suggests an association between maternal ZIKAV infection and congenital microcephaly. To project the timing of delivery of infants born to mothers infected during early pregnancy in 1 city in Bahia State, Brazil, we incorporated data on reported ZIKAV disease cases and microcephaly cases into a graphical schematic of weekly birth cohorts. We projected that these births would occur through February 2016. Applying similar projections to a hypothetical location at which ZIKAV transmission started in November, we projected that full-term infants at risk for ZIKAV infection would be born during April–September 2016. We also developed a modifiable spreadsheet tool that public health officials and researchers can use for their countries to plan for deliveries of infants to women who were infected with ZIKAV during different pregnancy trimesters.
