ROME, OCTOBER 13 – China is preparing to examine up to 200,000 blood samples taken in the city of Wuhan before the Covid 19 epidemic exploded, so until the last months of 2019, to help shed light on how and when the responsible coronavirus has passed from animal to man. CNN writes it exclusively, citing a “Chinese official”. The move, CNN recalls, was urged by the World Health Organization (WHO) last February. The blood samples in question, CNN writes, are kept in the Wuhan blood center. (HANDLE).
