Swine flu is continuing to spread in New Zealand, health officials said Monday as the death toll rose to 10 and some areas reported more people in hospital than during last year's pandemic. Although the World Health Organization (WHO) has declared the global pandemic over, H1N1 "is the most common strain of influenza circulating" in New Zealand, director of public health Mark Jacobs said. "So far this year there have been 10 deaths reported as linked to swine flu," he said, up from six a week ago. More than 500 people have been admitted to hospital with lab-confirmed swine flu so far this year with 16 treated in intensive care.
