New Delhi: The World Health Organisation asked China to share information on Covid to determine the origins of the virus.
China is holding back the vital data despite previously being asked to part with its understanding of the virus.
Tedros Adhanom Ghebreyesus , Director-General of the World Health Organization, said the international body continued to call on China to share the data and conduct the requested studies.
WHO's call comes days after a US researcher dubbed Covid 19 a 'man-made virus', further strengthening the speculations surrounding its origin.
The researcher added that the virus jumped out of the Wuhan Institute of Virology in China, before causing the pandemic.
The world first awoke to the shock of a fast-spreading outbreak of viral fever in China in December 2019.
Wuhan, the capital of Central China's Hubei province, became the theatre for the deadly virus.
Wuhan officials initially found the cases of pneumonia-like illness emerging from a wholesale seafood market in the city.
Even three years after the outbreak, China is still struggling to combat the virus with its controversial zero covid policy.
The debates still continue if SARS-CoV-2 emerged from China's Wuhan Institute of Virology (WIV) or a natural source.
Tedros Adhanom Ghebreyesus told the media that world still faces uncertainties and challenges, adding that only one in five people in low-income countries has been vaccinated.
"We continue to call on China to share the data and conduct the studies that we have requested, to better understand the origins of this virus," he reportedly said.
