Zika Virus Infection in Pregnancy: Maternal, Fetal, and Neonatal Considerations

Area of Science:

• Virology
• Epidemiology
• Maternal-Fetal Medicine

Background:

• Zika virus (ZIKV) infection is typically mild but poses significant risks during pregnancy.
• The epidemic highlighted the need for enhanced vector control and biomedical research.
• Congenital Zika syndrome (CZS) involves severe brain abnormalities, retinal issues, and limb defects.

Purpose of the Study:

• To summarize the known and reported consequences of ZIKV infection during pregnancy.
• To emphasize the vulnerability of pregnant women and the need for protective measures.
• To advocate for research into treatments, vaccines, and diagnostic tools.

Main Methods:

• Review of existing reports and literature on ZIKV infection in pregnancy.
• Characterization of Congenital Zika Syndrome (CZS) features.
• Analysis of the implications for public health and future research.

Main Results:

• ZIKV infection during pregnancy is linked to severe birth defects (CZS) and potential long-term neurodevelopmental issues.
• Pregnant women are the most vulnerable population.
• The full spectrum of ZIKV's impact on fetal development may extend beyond currently documented outcomes.

Conclusions:

• Expanded vector control programs are essential to reduce ZIKV transmission.
• Urgent research is required for safe and effective vaccines, treatments, and prenatal diagnostic tests for ZIKV.
• Protecting pregnant women and their fetuses from ZIKV requires a multi-faceted approach including public health interventions and scientific advancement.
