Abstrakt: To search for serological evidence of congenital infection in apparently healthy neonates born to women infected with the Chikungunya virus (CHIKV) during pregnancy, monitoring for CHIKV-specific antibodies was performed within the CHIMERE cohort study (Reunion island, 2006–2008). CHIKV-specific antibody kinetics showed no evidence of asymptomatic congenital infection as neonates were tested negative for CHIKV-specific IgM antibodies at birth and 368 infants with CHIKV-specific IgG antibodies seroreversed completely (mean seroreversion time: 7.7 months). Seroreversion time of transplacental CHIKV IgG antibodies was inversely correlated with the stage of pregnancy at which exposure took place and end-term small for gestational infants seroreversed earlier.
