Avian Influenza in Poultry

Germany (HPAI H7N7)
According to a World Organisation for Animal Health (OIE) report, an additional case of highly pathogenic H7N7 avian influenza has been reported at a poultry farm in Emsland, Lower Saxony. 50 chickens died and the remaining 10,054 were culled to prevent the disease from spreading. In addition to culling, all farms within a 3-km radius have been placed under quarantine, and those within 10 km are under observation. Poultry from three non-commercial flocks within a 1-km radius were also preemptively culled. The new farm is located only 1 km from a farm where low pathogenic H7N7 was identified in June. Investigations are underway to determine the source of the virus and whether there is a connection between the two farms.

Ghana (HPAI H5N1)
Four new outbreaks of the highly pathogenic H5N1 avian influenza virus have been reported at two farms and two backyard flocks in the Greater Accra region. A total of 7,786 ducks and chickens died, and the remaining 1,395 were culled to prevent further spread of the virus. The source of the outbreak is unknown.

In total, 236 chickens and ducks died and the remaining 3,036,083 birds were culled to prevent the virus from spreading. The source of the outbreak is unknown, and epidemiological investigations are still ongoing. Since the beginning of the currernt outbreak in 9/24/15, a total of 162 outbreaks have been detected.
