HPAI (highly pathogenic avian influenza)
“AI viruses are classified by a combination of two groups of proteins found on the surface of the virus: hemagglutinin proteins (H), of which there are 16 (H1-H16), and neuraminidase proteins (N), of which there are 9 (N1-N9). AI strains also are divided into two groups based on the pathogenicity of the virus–the ability of the virus to produce disease.
Low Pathogenicity Avian Influenza (LPAI): Most AI strains are classified as low pathogenicity and cause few clinical signs in infected birds. LPAI generally does not pose a significant health threat to humans. However, LPAI is monitored because two strains of LPAI-the H5 and H7 strains-can mutate into highly pathogenic forms.
High Pathogenicity Avian Influenza (HPAI): This is a more pathogenic type of avian influenza that is frequently fatal to birds and easily transmissible between susceptible species. The strain that is currently of concern in Southeast Asia, the Middle East, Africa and Europe is the H5N1 HPAI virus. http://www.usda.gov/wps/portal/usdahome?contentidonly=true&contentid=2005/11/0511.xml
