What did the world learn from the Ebola outbreak? That’s what VICE’s new documentary, “Evolution of a Plague,” aims to find out. Airing today on HBO, the documentary follows the course of the outbreak as it raged across Liberia, Sierra Leone, and Guinea last year, killing over 11,000 people.

First, VICE goes to Meliandou, a village in Guinea where scientists believe the epidemic began: infecting a toddler known as patient zero, then spreading afterward through family members, health care workers, and doctors. The documentary then examines what it was like on the frontline of the battle, at hospitals that weren’t properly equipped to handle such a disaster — pinpointing the ways that global health leaders can prepare and organize responses better next time.

“The world wasn’t prepared for this kind of outbreak when it happened,” Ron Klain, former Ebola response coordinator, tells VICE. “There was no prearranged group of responders ready to jump in quickly and deal with this kind of epidemic. We have to have that next time. We need to build CDC-like capacities in other countries around the world.”

According to Médecins Sans Frontières, the world still isn’t ready to handle another mass epidemic like Ebola. And it’s very possible that the next one could be even worse — an airborne virus that travels quickly and attacks a major city in a heavily populated country like India. It’s clear that the developed world and global health initiatives weren’t quick enough in their response with Ebola; how can they fix it for the next time? Watch HBO tonight to find out.
