Pregnancy outcomes of patients with prolonged viremia in a cohort study of pregnant women admitted to Centre Hospitalier de l’Ouest Guyanais, French Guiana, January 1–July 15, 2016. Description and outcomes of 14 pregnancies with prolonged maternal ZIKV viremia (including 1 with dichorionic twin pregnancy). Congenital ZIKV infection was confirmed in 9/15 (60%) fetuses, and 6/15 (40%) fetuses had adverse outcomes. Four of them had multiple abnormalities consistent with CZS (1 live birth, 1 TOP, 1 IUFD, and 1 stillbirth). The 2 fetuses from the dichorionic twin pregnancy also had adverse outcomes, with an IUFD at 24 wk and a TOP for severe ventriculomegaly in the other fetus at 29 wk. CSF, cerebrospinal fluid; CZS, congenital Zika syndrome; HC, head circumference; IUFD, intrauterine fetal demise; RT-PCR, reverse transcription PCR; TOP, termination of pregnancy; ZIKV, Zika virus.
