Abstract

Zika virus (ZIKV) has recently been confirmed as endemic in Indonesia, but no congenital anomalies (CA) related to ZIKV infection have been reported. We performed molecular and serological testing for ZIKV and other flaviviruses on cord serum and urine samples collected in October 2016 to April 2017 during a prospective, cross-sectional study of neonates in Jakarta, Indonesia. Of a total of 429 neonates, 53 had CA, including 14 with microcephaly. These 53, and 113 neonate controls without evidence of CA, were tested by ZIKV-specific real-time reverse transcription polymerase chain reaction (RT-PCR), pan-flavivirus RT-PCR, anti-ZIKV and anti-DENV IgM ELISA, and plaque reduction neutralization test. There was no evidence of ZIKV infection among neonates in either the CA or non-CA cohorts, except in three cases with low titers of anti-ZIKV neutralizing antibodies. Further routine evaluation throughout Indonesia of pregnant women and their newborns for exposure to ZIKV should be a high priority for determining risk.
