The head of the World Health Organization (WHO) says it is too early to declare that the swine flu pandemic has peaked worldwide. Dr. Margaret Chan says the outbreak of the H1N1 virus has peaked in the U.S., Canada and some other countries in the northern hemisphere. But not all countries have seen the peak and winter is still long, she was quoted as saying by the Associated Press. She tells the Geneva daily Le Temps that Africa has not seen a surge in the number of swine flu cases. That could be due to weak reporting or because the full outbreak there may be yet to come. She was scheduled to brief reporters Tuesday.
