In this Tuesday, March 10, 2020, photo released by China's Xinhua News Agency, Chinese President Xi Jinping talks by video with patients and medical workers at the Huoshenshan Hospital in Wuhan in central China's Hubei Province. Top Chinese officials secretly determined they were likely facing a pandemic from a novel coronavirus in mid-January, ordering preparations even as they downplayed it in public. Internal documents obtained by the AP show that because warnings were muffled inside China, it took a confirmed case in Thailand to jolt Beijing into recognizing the possible pandemic before them.
