Oregon has activated a multi-agency response plan after highly contagious avian influenza was found in domestic birds in Winston, in Douglas County.
There is no immediate public health concern, state officials said, and poultry and egg products remain safe to eat. The H5N8 avian influenza virus was confirmed by the US Department of Agriculture in guinea fowl and chickens from a backyard poultry flock of about 100 birds. The flock has access to the outdoors, where a pond and a marsh are frequented by migratory birds. Since November, 11 commercial poultry farms in Western Canada have been affected by an outbreak of the H5N2 variant. Last week, the H5N2 and H5N8 virus strains were identified in wild birds in Whatcom County, Washington, near the Canadian border, and H5N8 was found in captive falcons that had been fed some wild ducks. The finding in Oregon was quickly reported and identified due to increased awareness following those events, according to the Oregon Department of Agriculture. The virus has not been found in commercial poultry anywhere in the United States. ODA is the lead state agency responding to the incident, working withthe state Department of Fish and Wildlife, and Oregon Health Authority. USDA’s Animal Plant Health Inspection Service will play a key role in the response as well. Bird flu spreads quickly by direct bird-to-bird contact, but can also be carried by manure, tools, equipment, vehicles, egg flats, crates, clothing, shoes, and by migratory waterfowl. ODA is advising commercial poultry growers and backyard flock owners to be vigilant with biosecurity measures and surveillance. “Steps are being taken to contain the disease and we have not diagnosed avian influenza elsewhere in Oregon’s domestic poultry population, but the presence of the virus in migratory waterfowl poses a potential risk to our backyard poultry,” State Veterinarian Dr. Brad LeaMaster said. “We strongly encourage owners to take biosecurity measures to reduce the risk of spreading the disease,” he said. “That includes preventing contact between their birds and wild birds. We also want them to monitor their flock closely and report sick birds.” http://www.statesmanjournal.com/story/tech/science/environment/2014/12/19/highly-pathogenic-bird-flu-found-southern-oregon/20644807/ |

Jesus Christ died and was raised on the third day, the only "God" to overcome death.

Fujian H5N8 In Oregon Matches Europe and Japan Preliminary results indicate the HA sequence is 99.3% similar to A/bean goose/Korea/H40/2014 (H5N8 HPAI) based on a partial fragment of the HA gene. The neuraminidase sequence is 99.7% similar to A/Baikal teal/Korea/H80/2014 (H5N8) based on a partial fragment of the NA gene. The amino acid sequence at the hemagglutinin cleavage site is consistent with highly pathogenic avian influenza (HPAI). The above comments on the H5N8 outbreak in Winston, Oregon from theDecember 22 OIE report describe a small holding of 130, which included guinea fowl, chickens, ducks and geese, of which 28 had died prior to culling. The poly-basic cleavage site confirmed the HPAI indicated by the fatality rate, and the sequence similarity with H5N8 at Genbank indicate the Oregon sequences will be even more closely related to recent GISAID H5N8 sequences from Europe (Germany, Netherlands, England, Italy) and Japan, as well as the unpublished sequences from 4 pet falcons which died in Lynden after eating a wigeon caught near Wiser Lake in Whatcom County in Washington. The published H5N8 sequences in Europe and Asia have 3 gene segments (H5, PA, MP) from Fujian clade 2.3.4. Moreover, the reported H5N2 sequences in British Columbia have 5 of the 8 H5N8 gene segments, including Fujian H5. It is likely that a similar constellation is in the H5N2 sequences from a northern pintail from Wiser Lake. Full sequences from the US and Canadian outbreaks would be useful. |
