The World Health Organization has urged China to share data to help understand the origins of Covid-19, five years on from the start of the pandemic in the Chinese city of Wuhan.
On December 31, 2019, the WHO’s China office noted a cluster of “pneumonia” cases in a statement from health authorities in Wuhan. More than three weeks later, Chinese authorities locked down the city of 11 million.
Fears of a rapidly spreading virus gripped the nation, but – as authorities would later learn – the coronavirus had already spread far beyond China.
