Epidemiological comments As a precaution and in response to the recent HPAI outbreak in Canada, surveillance of poultry premises and of wild bird mortality events was enhanced by the USDA, and State personnel along the United States - Canadian Border. Through this surveillance, highly pathogenic avian influenza (HPAI) H5 was identified in wild birds. Two serotypes were identified on enhanced surveillance, both with amino acid sequence at the HA cleavage site consistent with HPAI, H5N8 and H5N2. H5N8 was identified in a captive wild gyrfalcon that was fed hunter killed wild birds from Whatcom County, Washington and H5N2 was identified in a wild pintail duck also from Whatcom County, Washington. Based upon direct sequencing from gyrfalcon specimens, an avian influenza subtype H5N8 of Eurasian lineage (partial H5 99% similarity to A/coot/Korea/H81/2014 and partial N8 99% similarity to A/Baikal teal/Korea/H41/2014). The amino acid sequence at the hemagglutinin cleavage site is consistent with highly pathogenic avian influenza (HPAI). Preliminary data suggests that these virus strains (H5N2 and H5N8) may be related with the H5N8 strain potentially representing the progenitor; however further analysis is needed. Neither of these viruses has been found in any poultry in the United States. These H5N8 and H5N2 detections involve only wild birds. Further investigation and characterization of the HPAI viruses is ongoing.

How long do you give it, Dr. Niman, before one or the other (or both) is found in US poultry?

They have probably already been found but not yet confirmed / reported.

USDA Confirms H5 Avian Influenza in Washington State Wild Birds
H5N2 Found in Northern Pintail Ducks & H5N8 Found in Captive Gyrfalcons
WASHINGTON, Dec. 16, 2014— The United States Department of Agriculture’s
(USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of
highly pathogenic (HPAI) H5 avian influenza in wild birds in Whatcom County,
Washington. Two separate virus strains were identified: HPAI H5N2 in northern pintail
ducks and HPAI H5N8 in captive Gyrfalcons that were fed hunter-killed wild birds.
Neither virus has been found in commercial poultry anywhere in the United States.
There is no immediate public health concern with either of these avian influenza viruses.
Both H5N2 and H5N8 viruses have been found in other parts of the world and have not
caused any human infection to date.
The finding in Whatcom County was quickly reported and identified due to increased
surveillance for avian influenza in light of the HPAI H5N2 avian influenza affecting
commercial poultry in British Columbia, Canada.
Washington State, USDA, and other Federal partners are working jointly on additional
surveillance and testing of birds in the nearby area.
All bird owners, whether commercial producers or backyard enthusiasts, are encouraged
to practice good biosecurity, prevent contact between their birds and wild birds, and to
report sick birds or unusual bird deaths to State/Federal officials, either through your state
veterinarian or through USDA’s toll-free number at 1-866-536-7593. Additional
information on biosecurity for backyard flocks can be found at
healthybirds.aphis.usda.gov

Wild duck, captive falcon infected with bird flu in Washington

Capital Press
Published:
December 16, 2014 5:23PM

Officals say avian flu has been found in Washington state. Ten British Columbia poultry farms have been infected with a highly contagious strain of avian influenza.

Officials say a wild duck and a captive falcon in Whatcom County in northwest Washington state were infected with highly pathogenic avian influenza, similar to the virus killing thousands of chickens and turkeys in British Columbia.

The H5N2 virus, which has struck 10 B.C. poultry farms, was found in a northern pintail duck. A separate highly contagious avian influenza strain, H5N8, was found in a gryfalcon, which died after eating a hunter-killed wild duck.

Both types are equally dangerous, State Veterinarian Joe Baker said. Further tests will have to be conducted to determine whether the H5N2 virus found in the Whatcom County duck precisely matches the genetic makeup of the strain in B.C., he said.

Avian influenza has not been found in any Washington poultry, state Department of Agriculture spokesman Hector Castro said. The department has stepped up testing of flocks in Whatcom County since the outbreak in Canada.

Baker said he believes this was the first time a highly pathogenic strain of avian influenza has been found in Washington state.

He encouraged poultry owners in northwest Washington to alert WSDA to ill birds. “We feel like testing dead and sick and birds will be very important,” he said.

WSDA will hold a town hall meeting at 6 p.m. Thursday, Dec. 18, in the Mount Baker Rotary Building at the Northwest Washington Fairgrounds in Lynden to discuss avian influenza and steps poultry owners should take to protect their birds.

The meeting will be open to the public. WSDA particularly encouraged poultry producers or owners of backyard flocks to attend.

The virus was first reported in British Columbia on Dec. 1 and has killed or forced authorities to euthanize 233,800 birds, according to the Canadian Food Inspection Agency.

The H5N2 virus was confirmed Dec. 13 at a 10th operation, a 53,000-acre chicken farm in Langley, about 29 miles east of Vancouver.

The farm was the largest and the first outside the Abbotsford-Chilliwack area, which is farther east and near the Washington border.

Castro said publicity about the disease outbreak in Canada prompted the falcon owner in Washington to report its death.

Swab samples from the captive gyrfalcon were sent to the Washington State University Avian Health & Food Safety Laboratory in Puyallup. The USDA’s National Veterinary Services Laboratory in Iowa confirmed the positive tests over the weekend.

Baker called the wild duck that the falcon ate the “smoking gun,” though further USDA tests will have to be done on meat leftover from the duck to confirm whether that’s what gave the falcon the virus.

It was not immediately known where the hunter killed that duck.

The other duck, a northern pintail, was found at Wiser Lake south of Lynden, Baker said.

Humans are rarely affected by avian influenza and there has never been a reported instance of a person becoming ill from an infected bird in the United States, although some cases have occurred in foreign countries where people have come in close contact with infected birds, according to WSDA.

The virus can be spread by direct contact with infected birds, contaminated equipment and through airborne transmission over short distances. The virus is found in feces, saliva and respiratory secretions of birds carrying the disease.

Signs of infection include decreased appetite, coughing and sneezing, lowered egg production, greenish diarrhea, excessive thirst and swollen wattles and combs.

Persons seeing sickness in domestic birds are asked to contact the WSDA Avian Health Program at 1-800-606-3056. Sick and dead wild birds should be reported to the Washington Department of Fish and Wildlife at 1-800-606-8768.

Avian flu confirmed in wild birds in US
Updated: 9:11 pm, Wednesday, 17 December 2014

US agriculture officials have found avian influenza in wild birds in Washington state but say there's no immediate public health concern.

The US Department of Agriculture said separate strains of the H5 virus were identified in a northern pintail duck and a gyrfalcon.

Both viruses have been found in other parts of the world and have not caused any human infection to date, the USDA said. Neither virus has been found in commercial poultry in the US.

An avian influenza outbreak this month in southwest British Columbia spread to several poultry farms, and 155,000 birds have died of the virus or will be euthanised, Canadian officials said last week.

'There's really no reason to panic. This does not represent an increased risk to people,' said Dr. Kristin Mansfield, a veterinarian with the Washington Department of Fish and Wildlife.

'There's very little to no risk of these viruses affecting people.'

The state's two confirmed cases are a captive falcon with the H5N8 strain of avian flu, and a wild duck with the H5N2 strain, said Hector Castro, a spokesman for the state Department of Agriculture.

The falcon had been fed wild birds killed by hunters.

Castro said that after the Canadian outbreak, the state stepped up random testing in domestic poultry flocks near the border and put out information to other bird owners.

The falcon was diagnosed after its owner took it to a veterinarian, who then reported its death to the state. A USDA lab in Iowa confirmed the virus over the weekend.

Official Information on the Recent Cases of Avian Flu in WA

There’s been a lot of discussion about a recent case of Avian Influenza that was reported in waterfowl at Wiser Lake in Whatcom County, which is very near the Canadian border. While the avian influenza virus (aka ”bird flu”) has recently been problematic with the poultry industry in British Columbia, the strains identified in Whatcom County are not the same as the one identified in BC (HPAI H5N2). More research is underway.

Unfortunately, the way these cases came to light was tragic. Many of you may know Dan Pike, who also lives very near the border. One of Dan’s falcons caught a duck and then he fed that duck to a few of his other birds. All four of his falcons that ate the duck died within a few days and were sent off to be tested for cause of death. The first two falcons that died came back positive for a highly pathogenic strain of the virus (HPAI H5N8); the results on the other two falcons are still pending. His other raptors, which have not shown signs of influenza, have been confined to his property and are being closely monitored. It is unknown whether this strain of influenza can also infect humans; because of this Dan and his wife are also being monitored.

On behalf of myself, his friends, and his falconer brothers and sisters: our hearts go out to Dan and his wife for the loss of their birds. You are in our thoughts and we are there for you. - Brad Felger

Effective immediately, those of us that live in the northwest corner of Washington State should NOT feed ducks caught this season to our raptors until more is known. Freezing the ducks does NOT kill this particular virus.

* There is a Town Meeting being held in Lynden this Thursday to discuss avian influenza and what backyard poultry breeders, etc. can do to protect their birds. (http://agr.wa.gov/News/2014/14-25.aspx)


* The USDA has released a bulletin containing all information known so far. It is highly recommended that you read it. (http://www.aphis.usda.gov/publications/ ... luenza.pdf)


* The USGS has also released a document. (http://www.nwhc.usgs.gov/publications/w ... 5_H5N8.pdf)


* There’s more information on the WDFW site. (http://wdfw.wa.gov/conservation/health/ ... index.html)
Interesting detail: four falcons died after eating a duck that one of the falcons had killed.
