The World Health Organisation kept its pandemic flu alert at phase 5 on a six-level scale today and repeated a call for countries not to restrict travel because of the H1N1 influenza outbreak, according to Reuters. After a meeting of its emergency committee, the U.N. agency said it had agreed in future to take into account the severity of a flu outbreak and not just its geographical spread when announcing alert changes. Phase 6 means a full pandemic is in progress and phase 5, the current level, means one is imminent.
