Understanding the Zika Virus

The video discusses the Zika virus, its origins, and its potential link to microcephaly in newborns. Initially considered harmless, Zika has raised concerns due to a significant increase in birth defects in Brazil. The virus is spread by Aedes mosquitoes and causes mild symptoms in most cases. With no vaccine available, prevention focuses on avoiding mosquito bites. Researchers are investigating the virus's behavior and potential mutations. The video emphasizes the urgency of understanding Zika, especially with upcoming international events like the Olympics.
