When the 2009 H1N1 flu virus emerged last April, it triggered the first new pandemic in more than 40 years, producing endless headlines and panic. But, now, some 10 months into the pandemic, the publicâ??s fear has subsided. H1N1 turned out to be relatively weak, and action by global and national health officials has helped blunt the damage caused by the virus; by mid-February, more than 16,000 people worldwide had died from the new flu, according to the World Health Organization (WHO), but that figure is in line with mortality in a normal flu year.
