In June 2009, the WHO declared that a new flu virus was causing the first pandemic in more than 40 years. It first emerged in Mexico and the United States.
Based on recent reports from the southern hemisphere, where it’s winter, the WHO says H1N1 is now behaving more like a seasonal flu.
The latest update from the U.N. health body said: “Globally, pandemic influenza transmission remains most active in parts of South Asia and in limited areas of tropical South and Central America. In the temperate zone of the southern hemisphere, overall seasonal and pandemic influenza activity remains low, except in South Africa.”
