One year ago, Wuhan, the city in Hubei Province, China where COVID-19 was first documented, went on lockdown. Two anonymous reporters covertly recorded inside a Wuhan hospital, where healthcare workers were too busy to monitor what they were capturing. The resulting documentary, "76 Days," directed by filmmaker Hao Wu and produced by MTV Documentary Films, provides an intimate and dire look inside a hospital as it faced PPE shortages, uncertainty, and an onslaught of patients infected with a virus that, at the time, we knew almost nothing about. Hao Wu joins us to talk about making this film and his experience documenting the genesis of what would, months later, become a global pandemic.
