Zika's Silent Threat: Birth Defects Revealed
23 Jun
Summary
- Zika virus, first identified in Uganda in 1947, spread globally.
- A 2015 epidemic in Brazil linked Zika to severe microcephaly in newborns.
- Transmission occurs via mosquitoes, sexual contact, and mother-to-child.

First identified in Uganda in 1947, the Zika virus has since spread from Africa and Asia to the Americas. Outbreaks were recorded across Africa, the Americas, Asia, and the Pacific following its initial identification.
The virus gained significant attention following a large epidemic in Brazil in 2015. During this outbreak, researchers observed an unexpected outcome: pregnant women infected with Zika gave birth to babies with severe microcephaly, a condition characterized by an abnormally small head size.
While most Zika virus infections are asymptomatic, individuals who do develop symptoms typically experience mild, short-lived effects. However, the primary danger lies in its transmission to pregnant women, which can lead to serious congenital abnormalities in their infants, including miscarriage and preterm birth.
Transmission routes include the bite of infected Aedes mosquitoes, sexual contact, and mother-to-child transmission during pregnancy. There is no specific antiviral treatment for Zika; care is supportive, focusing on rest, fluids, and pain relief. Prevention strategies target mosquito bite avoidance and safer sexual practices.
