Now WHO warns of threat of ‘Mu’ variant found in Colombia – and it’s already been spotted in Britain

World Health Organization bosses are now officially tracking another Covid variant named ‘Mu’.

The mutant strain — which also has the scientific name B.1.621 — was first detected in Colombia in January.

Almost 4,000 cases have been spotted since then, and it has spread to more than 40 countries.

Nearly 50 cases of Mu have been spotted in Britain so far, and hundreds have been identified in the US.

The WHO’s weekly bulletin claimed its mutations suggest it may be more resistant to vaccines, as was the case with the South African ‘Beta’ variant. There are fears it may be more infectious, too.

But the agency warned more studies would be needed to examine this further, with the WHO having now formally labelled Mu a ‘variant of interest’.
