Experts from the World Health Organization met Chinese officials today ahead of their first site visits in Wuhan for a coronavirus origins probe which will take in a food market presumed to be "ground zero" of the pandemic.
The fieldwork was set to begin in earnest in the afternoon, after being hobbled by delays and amid fears over access and the strength of evidence a year after the virus emerged.
The team will visit hospitals, as well as meeting scientists, first responders and some of the early patients to be hit by the then-unknown coronavirus that has gone on to kill more than two million people across the world and flatline the global economy.
