Higher levels of ZIKV NAbs titers were detected among mothers of microcephaly neonates with laboratory confirmation of recent ZIKV infection (qRT-PCR and/or ZIKV-specific IgM) (n = 31) when compared to that of mothers of controls without microcephaly (p = 0.010; Fig 2). The gene discussed is CD40LG; the disease is Zika virus infectious disease.
