Abstract
In her opening address to the 2011 session of the World Health Organization's governing body, the World Health Assembly, WHO's Director-General, Dr. Margaret Chan, noted that WHO's job was much more straightforward when it was dealing mainly with germs, hygiene, medicines, vaccines and sister sectors, like water supply and sanitation. Today, international public health governance is much more complex. It is not only about forging agreement around shared health problems, but also being concerned with health as an outcome of global policies in areas such as trade, intellectual property, and human rights and, nationally, as an outcome of work in other sectors such as education, agriculture and the environment. Global health governance is increasingly fragmented, and WHO is not the only health game in town.
