On January 11, 2020, health officials in the central Chinese city of Wuhan reported that a 61-year-old man had died from complications of pneumonia caused by a previously unknown virus. The disclosure came after authorities had reported dozens of infections over several weeks by the pathogen later named SARS-CoV-2, which is understood to be the cause of Covid-19. It went on to spark a global pandemic that has so far killed over 7 million people and profoundly altered societies around the world, as well as life in China itself. FILE IMAGES of Wuhan in 2020
