The US health secretary has urged the World Health Organization to ensure the next phase of investigation into Covid-19’s origins is “transparent”.
Speaking to a ministerial-level WHO meeting, Xavier Becerra said international experts should be allowed to evaluate the source of coronavirus.
US media reports suggest growing evidence the virus could have emerged from a laboratory in China.
Covid-19 was first detected in 2019 in Wuhan, in central Hubei province.
Since then, more than 167 million cases and 3.4 million deaths have been reported worldwide.
