Looking Beyond Zika

Zika is just the latest in a series of vector-based diseases experiencing a global resurgence. Why are these diseases, once thought to be firmly under our control, prevalent once again?

Scientists continue to point to urbanization, world travel and climate change as 3 contributing factors. However, Zika’s own genetic mutation, along with the fact that local transmission of Zika did not occur in the Americas until 2014, clouds the picture.

As Zika moves to urban environments in wealthier countries, more scientists—better equipped than ever before—are studying the virus, in their quest to answer enduring questions about vector-based diseases and defend against future outbreaks.
