Overview of the HPAI (H5N1) situation in the world

20 December, 2007

According to a preliminary report from the United Nations Food and Agriculture Organization (FAO), in 2007 there has been an improvement in the general HPAI (H5N1) situation worldwide, but there is still a risk of recurrence and spread of the infection, and the disease is becoming enzootic in some regions. Except for sporadic outbreaks in wild birds, most of the H5N1 cases this year occurred in domestic poultry, such as chickens, turkeys, geese, ducks, and quail. The H5N1 outbreaks seemed to follow a seasonal pattern, particularly high between January and April 2007, with a peak in March, and outbreaks were concentrated mainly in Asia and Africa.
