Avian Influenza in Poultry
China (HPAI H5N6)

The World Organisation for Animal Health (OIE) reports a new case of highly pathogenic H5N6 avian influenza virus on a farm rearing black swans and peacocks in the province of Hunan. Of the 165 birds confirmed by the Harbin Veterinary Research Institute to have the disease, 91 died, and an additional 1,132 were culled to prevent further spread of the disease. Further control measures include movement control, screening, disinfection, modified stamping out, and zoning. The source of this outbreak is unknown.

Egypt (HPAI H5N1)
The Poultry Epidemics and Diseases at the Agriculture Ministry confirmed cases of avian influenza in 16 locations in the Sohag, Qena, Aswan, and North Sinai Governorates. The director of the Ministry, Moussa Suleiman, reports that all birds at these locations, 14 in farms and 2 at markets, have been vaccinated. As a precaution against the disease, a ban on importing birds is currently in place until March. On January 16 in the Sharqia Governorate a 30-month-old child reportedly died of avian influenza. The Ministry further notes that although 1,024 cases of suspected avian influenza in people have been reported in Egypt since November, most of these tested negative.

Officials from the Animal Resource Development Department (ARDD) have reported a case of H5N1 avian influenza virus in chickens and ducks at a government poultry farm at Gandhigram. Samples were taken after suspicious deaths were observed; avian influenza was confirmed by a laboratory in Bhopal. To prevent any spread of the disease, over 8,500 birds were culled and 10,500 eggs destroyed. As a further precaution, officials have plans to cull poultry within a 1 km radius in the near future.
