Geflügelpest
Influenza A viruses spread in the air and in manure, and survives longer in cold weather. They can also be transmitted by contaminated feed, water, equipment, and clothing; however, there is no evidence the virus can survive in well-cooked meat. Symptoms in animals vary, but virulent strains can cause death within a few days. Avian influenza viruses that the World Organisation for Animal Health and others test for to control poultry disease include H5N1, H7N2, H1N7, H7N3, H13N6, H5N9, H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, and H12N5.
