Beijing/London | A top Chinese scientist has said China investigated whether COVID-19 might have originated in a Wuhan laboratory – the first admission from a senior official that Beijing took the so-called lab leak theory seriously after years of heated denials.
Professor George Gao, former head of the Chinese Centre for Disease Control and Prevention, told a BBC Radio 4 podcast that the Wuhan Institute of Virology was checked by experts to see whether the facility could have been the source of the coronavirus pandemic.
