Beijing has come under pressure to consider a fresh probe into the origins of the pandemic after a delayed and heavily politicised visit by a World Health Organization team of international experts that failed to conclude how the virus first broke out.

US intelligence has ruled out that the coronavirus was developed as a weapon, and most agencies assess with 'low confidence' it was not genetically engineered.

WHO says 'the politics have really contaminated the environment and changed the atmosphere' of the origins investigation.

China says calls for further data are motivated by politics instead of scientific inquiry.

The global public may never know the full truth about the virus' origins, particularly if China continues to be uncooperative.
