Technical Abstract: Avian influenza (AI) infections of poultry continue to be reported around the world in various countries. Most reports have been of mildly pathogenic (MP) AI, especially of H9N2 in Asia. Two highly pathogenic (HP) outbreaks were reported: Hong Kong (H5N1) and Pakistan (H7N3). MP AI (H5N2) continues to circulate in Mexico and Guatemala, and was reported for the first time in El Salvador during 2001. These three Central American MP AI viruses (H5N2) are of the same phylogenetic lineage. MP and HP AI continue to be a poultry health problem around the world.
