Zika outbreak: How the Zika virus damages the brain

The video discusses the severe birth defect microcephaly, characterized by an abnormally small head. It explains how a virus, when injected into pregnant mice, targets the placenta, allowing it to infect the fetus. The virus travels to the brain, infecting neural progenitor cells and turning them into viral factories. This process disrupts brain development, leading to structural abnormalities similar to those seen in babies with microcephaly.
