GENEVA: The World Health Organisation (WHO) will convene a meeting of members to discuss strategies to counter a new, more infectious coronavirus strain that emerged in Britain, its European chief said on Tuesday. He did not give a date for the meeting. 'Limiting travel to contain spread is prudent until we have better info. Supply chains for essential goods & essential travel should remain possible,' WHO Regional Director Hans Kluge said on Twitter, urging increased preventive measures. The Geneva-based body has cautioned against major alarm over the variant, saying it was a normal part of a pandemic's evolution and praising Britain for detecting it. In a statement on Tuesday, the WHO repeated that there was not yet enough information to determine whether the new variant could affect vaccine efficacy, saying researching was ongoing.
