The WHO added it was not officially declaring a pandemic, signified by a move to pandemic alert level six, the highest possible.
Dr Keiji Fukuda, assistant director-general for health, security and environment at the WHO, said: ‘We don’t have evidence to suggest we should move to phase six, or that any such move is imminent.’
