The world may never find "patient zero" in its search for the origins of Covid-19, Maria Van Kerkhove, World Health Organization's technical lead on the disease, said on Friday.
A WHO-led team investigating the origins of Covid-19 is to hold virtual meetings with its Chinese hosts in Wuhan, where the pandemic first emerged more than a year ago.
