Popis: Background The 2005–06 chikungunya virus (CHIKV) outbreak in La Réunion suggested that mothers could transmit CHIKV to their neonates while viremic during the intrapartum period, and more than half of the infected neonates showed impaired neurodevelopment at two years of age. However, data sparsity precluded an overview of the developmental impact of vertical infection within the whole prenatal period. Objective & methods The current study assessed two-year old children born to mothers who were infected during the 2014 CHIKV outbreak in Grenada to determine the neurodevelopmental impact of perinatal CHIKV infection throughout gestation. Mother and child infection status were confirmed by serologic testing (IgG and IgM) for CHIKV. Cognitive, fine motor, gross motor, language and behavioral outcomes were assessed at two years of age on the INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA). Results No differences in neurodevelopmental outcomes were observed between two-year-old children born to mothers infected with CHIKV during gestation (n = 149) and those born to mothers not infected with CHIKV (n = 161). No differences were found in INTER-NDA scores between children infected with CHIKV (n = 47) and children not infected with CHIKV (n = 592). Likewise, there were no differences between children infected with CHIKV post-partum (n = 19) versus children not infected with CHIKV (n = 592). Conclusion Our findings suggest that children exposed and/or infected with CHIKV outside of the intrapartum period experience no significant neurodevelopmental delay at two years of age, as measured by the INTER-NDA, compared to their unexposed and/or uninfected peers. These results complement those of previous studies which showed a neurodevelopmental risk only for children infected during the intrapartum period, while the mother was highly viremic. These results might be reassuring for women of childbearing age and public health officials in CHIKV-endemic regions.
Author summary The Chikungunya virus (CHIKV) can negatively impact fetal neurodevelopment and consequent neurocognitive functioning in young children. Studies from La Réunion island demonstrated that, compared to their uninfected counterparts, children infected by CHIKV during the intrapartum period were at increased risk for deficiencies in the frontal lobes where the language and coordination centers are located, as well as slight deficits in other neurocognitive skills like sociability, movement and posture. The current study assessed two-year old children born to mothers infected during the 2014 CHIKV outbreak in Grenada to determine the neurodevelopmental impact of perinatal infection throughout gestation. No differences in neurodevelopmental outcomes were observed between two-year-old children born to mothers infected with CHIKV during gestation and those born to mothers not infected with CHIKV, nor between children infected with CHIKV and children not infected with CHIKV. Our results support previous findings that a small proportion of children born in CHIKV-endemic regions are at risk as only mothers viremic during the intrapartum period are at risk of infecting their neonates. Healthcare providers in CHIKV-endemic regions may wish to monitor for CHIKV symptoms when pregnant women are near term. The relatively high symptomatic rate seen with CHIKV infection (75%) makes such monitoring feasible.
