Co-infection with Zika and Chikungunya viruses associated with fetal death-A case report.

We describe a case of fetal death associated with a recent infection by Chikungunya virus (CHIKV) in a Brazilian pregnant woman (positive RT-PCR in blood and placenta). Zika virus (ZIKV) infection during pregnancy was also identified, based on a positive RT-PCR in a fetal kidney specimen. The maternal infection caused by the ZIKV was asymptomatic and the CHIKV infection had a classical clinical presentation.
