In this PBS FRONTLINE documentary, doctors and scientists confront the untold story of the coronavirus pandemic, and assess how key missteps failed to contain the outbreak.

In January of 2020, the Chinese government announced that the city of Wuhan had been placed under lockdown amid the emergence of a deadly new virus.

But the virus had already been spreading in the region for 54 days.

Jane McMullen is an award-winning filmmaker whose previous work includes Escape from Dubai and Weinstein: The Inside Story.

In this documentary for PBS FRONTLINE, medical and scientific experts assess China's public response to the coronavirus outbreak, digging beyond the official government narrative.

To this day, the Chinese government insists that it acted in a timely manner and responded to the outbreak appropriately.

But China's COVID Secrets calls into question how soon the country's government knew what it was dealing with, and why it failed to act sooner.
