Avian Influenza in Animals South Korea (HPAI H5N8)
According to the Ministry of Agriculture, Food and Rural Affairs, the highly pathogenic H5N8 avian influenza has been confirmed in one of three dogs at an affected duck farm in southeastern South Korea. It is believed the dog may have consumed infected ducks. No antigens or antibodies were found in the other two dogs, suggesting no dog-to-dog transmission of the virus. All three dogs have been culled. Taiwan (H5)
The Council of Agriculture reported that a rare black-faced spoonbill found dead in Tainan?s Cigu District tested positive for the H5 avian influenza virus. The exact strain of the virus is unknown, and it is not known whether the strain is related to the multiple highly pathogenic H5 strains circulating in poultry on the island. To prevent further spread of the virus, all avian livestock farms within a 1 km radius will be monitored.

Nigeria (HPAI H5N1)
A poultry farm in Mando, Kaduna State has tested positive for the highly pathogenic H5N1 avian influenza virus. This marks the 12th state to be positive for H5N1 this year.

UK (LPAI H7) An outbreak of the low pathogenic H7 avian influenza virus has been confirmed at a chicken breeding farm in Upham, Hampshire, England. 52 birds have died and laboratory results indicate that the virus is the N7 sub-type, but further testing is needed to confirm.

USA (HPAI H5N8)
Nevada agricultural officials reported a case of highly pathogenic H5N8 avian influenza in a hunter-harvest mallard duck in Lincoln County.

An additional case of highly pathogenic H5N8 avian influenza was reported in a 4-H flock of chickens and waterfowl in Oroville, Washington. A much larger flock in Riverside, Washington, has also been infected. The 5,000 birds of mostly game birds at the Riverside farm will be culled before the smaller Oroville flock. A quarantine has been set around both infected farms, and government officials have sampled 21 nearby flocks to see if the virus has spread.
