The head of the World Health Organisation (WHO) has called for further investigation of suggestions the Covid-19 virus may have spread from a Wuhan laboratory.
Major nations, including the US and UK, expressed concerns over Beijing’s lack of transparency during a probe into the origins of the virus.
Tedros Adhanom Ghebreyesus said data had been withheld from investigators looking into the source of the virus, which is believed to have originated in the city of Wuhan.
The UN agency said China had refused to give raw data on early Covid-19 cases to the WHO-led team, potentially complicating efforts to understand how the global pandemic began.
Although investigators concluded that a leak from a Wuhan-area laboratory was the least likely hypothesis for the origins of SARS-CoV-2, Dr. Tedros said the matter required further analysis – potentially including additional missions back to China.
