The challenge of the laboratory diagnosis in a confirmed con
Zika virus (ZIKV) has caused one of the most challenging global infectious epidemics in recent years because of its causal association with severe microcephaly and other congenital malformations. The diagnosis of viral infections usually relies on the detection of virus proteins or genetic material in clinical samples as well as on the infected host immune responses. Serial serologic testing is required for the diagnosis of congenital infection when diagnostic molecular biology is not possible.

A 2-year-old girl, born to a mother with confirmed ZIKV infection during pregnancy, with a confirmed ZIKV infection in utero, showed at birth a severe microcephaly and clinical characteristics of fetal brain disruption sequence compatible with a congenital ZIKV syndrome (CZS). The patient was followed-up as per protocol at approximately 1, 4, 9, 12, 18–21, and 24 months of age. Neurological, radiological, audiological, and ophthalmological assessment were performed during this period of time. Prompt rehabilitation was initiated to prevent potential adverse long-term neurological outcomes.

The growth of this girl showed a great restriction at 24 months of age with a weight of 8.5 kg (−2.5 z-score) and a head circumference of 40.5 cm (−4.8 z-score). She also had a great neurodevelopmental delay at the time of this report.
