Will people even hear this? Time will tell but we should know soon enough.

I thought it would freak me out to hear that it is here. I am so glad that I have this forum, surely without it I would have. Thanks all for your information. We are ready, let's help the others.

Had to switch to CSPAN to watch the briefing.  Hopefully, the clinton/gates live coverage won't pre-empt this story as did the former isreal prime minister story.
 
Anyone in Michigan that can provide local coverage??

White House: Lesser bird flu may be here

Associated Press

WASHINGTON - Scientists have discovered the possible presence of bird flu in wild mute swans in Michigan - but it does not appear to be the worrisome, highly pathogenic strain, the White House announced Monday.

"They believe it is a strain of low pathogenicity, similar to strains that have been seen before in North America," White House spokesman Tony Snow said.

Testing is still being done to confirm the presence of the virus and its type, officials said.

Scientists had feared that the deadly H5N1 strain of bird flu would reach North America sometime this year. Just last week, the U.S. expanded monitoring of wild migratory birds throughout the nation, to check for early warning signs.

However, health officials stress that the virus' appearance in wild birds would not be a public health crisis - especially if it were the less worrisome, low-pathogenic strain.

We knew it would get here eventually.  I am just glad that is being reported as H5N1 and that they are testing to see if it is High Path!

OK, last article I'll post as they all say about the same thing.  This one a little more.
 
I am so glad this story has taken off like wildfire!  It is all over every U.S. news outlet - within 15-30 min of first being reported.  Maybe there is hope after all.
 
 
 
 
Bird Flu Found in Michigan Swans


WASHINGTON (AP) -- Scientists have discovered the possible presence of bird flu in wild mute swans in Michigan -- but it does not appear to be the most worrisome, highly pathogenic strain, the White House announced Monday.

"They believe it is a strain of low pathogenicity, similar to strains that have been seen before in North America," White House spokesman Tony Snow said.

Testing is still being done to confirm the presence of the H5N1 virus and its type. Officials with the Agriculture and Interior departments were to announce details later Monday morning.

Scientists had feared that the deadly H5N1 strain of bird flu would reach North America -- in birds -- sometime this year. Just last week, the U.S. expanded monitoring of wild migratory birds throughout the nation, to check for early warning signs.

However, health officials stress that the virus' appearance in wild birds would not be a public health crisis -- especially if it were the less worrisome, low-pathogenic strain.

The H5N1 virus has killed at least 138 people worldwide since it began ravaging Asian poultry stocks in late 2003. But virtually all caught the virus from close contact with sick birds or their droppings.

Health officials are closely watching H5N1's march around the globe for fear the virus eventually could mutate into a strain that could spread easily from person-to-person, possibly sparking a worldwide epidemic. No one knows how likely that is to happen, and specialists agree that the risk doesn't jump even if a few infected birds are found to have entered the U.S.

But if that happens, it could trigger additional security steps, especially to prevent wild birds from infecting U.S. poultry flocks, and more stringent monitoring.

Wild birds, especially waterfowl, carry a multitude of flu viruses -- and officials have repeatedly warned that this first batch of testing could produce a lot of false alarms.

Only confirmatory tests that will take several more days -- possibly up to 10 -- can tell whether a suspect bird really has H5N1 or some other harmless flu strain. If so, that testing also will confirm whether the virus is the so-called "high-pathogenic" version, the deadly type, or a so-called "low-pathogenic" version, a mild type not of concern for humans.

This is an old article that outlines what procedures they will use for testing and reporting the resutls to the public.
 
AMES, Iowa ~ Agriculture Department prepares for bird flu testing
http://www.avianflutalk.com/forum_posts.asp?TID=8647&PN=1

AMES, Iowa (AP) - The government's elaborate network for diagnosing bird flu will eventually come down to a sprawling 640-acre campus in the Iowa countryside where strict security is the only hint of the crucial role scientists there could play in a national drama that the country hopes will never materialize.

The security and the elaborate protective clothing the Agriculture Department scientists wear - scrubs, coveralls, rubber boots, protective glasses, hairnets and gloves - looks like a made-for-TV disaster movie....."

"Samples will be shipped to a network of laboratories across the country for screening. If a sample contains evidence of the H5 virus, it then gets shipped to Ames, where tests are run over several days to determine if the infected bird carried the H5N1 strain.

First, virus from the sample is injected in bird eggs, which are tested five days later to determine whether it is one of 144 strains of bird flu or whether it is another disease such as Exotic Newcastle, which is harmless to humans but deadly to poultry.

If it contains bird flu, the sample is tested to determine whether it is H5N1 or another of the avian influenzas. Only those testing positive for H5N1 go to the lab with the caged chickens.

Eight of these birds, specially bred and disease-free, are injected with virus from the suspect sample. Perhaps within hours, certainly in two days, the birds will begin moving more slowly, perhaps hunching in the corner of the cage and no longer eating and drinking. Their wattles might turn from bright orange to blue.

"If you lose 75 percent of the chickens, or more, then it's high-path," said Brundaben Panigrahy, head of the lab's avian section, using scientists' shorthand for the lethal strain of Asian bird flu.

Although the test results will be announced publicly, likely by officials in Washington, Granger said this will not be a signal of a threat to humans."

Note by Jhetta:  It looks like they now think it is Low Path H5N1... they found Low Path H5N1 in Canada last August... lets hope that additional test's prove that it is indeed Low Path H5N1
 
Note... Low Path H5N1 has previously been found in the US.
 
 
LAURAN NEERGAARD
Associated Press

WASHINGTON - Scientists have discovered the possible presence of bird flu in wild mute swans in Michigan - but it does not appear to be the most worrisome strain, the Bush administration announced Monday.

The birds might have the H5N1 virus - confirmatory tests are under way - but other tests have ruled out that it could be the highly pathogenic version of that virus that has ravaged poultry in many other countries, Agriculture Department officials said.

"This is not the highly pathogenic avian influenza virus that has spread through much of other parts of the world," said Ron DeHaven, administrator of USDA's Animal and Plant Health Inspection Service.

"We do not believe this virus represents a risk to human health," he declared.

What low strain are they talking about? I saw a few article on news now bird flu, but no mention of the low path strain. This is coming from the White House, so it seems important.  There are at 6 or more stories floating on the wires.
 
MedClinician -- can you get confirmation on the strain?

my feelings too, Angie.  I'm so glad they're reporting even low-path - maybe it will bring people back to the potential of a pandemic so that they can take precautions.  Don't blame you a bit for your move, Mary R. 
As we've seen, even the less lethal varieties can mutate overnight.

No H5N1 is not always High Path.... it became High Path in Asia.... And is so far NOT High Path in North America.
 
 
"To date this High Path form of H5N1 Avian Influenza has not been found in the U.S. However, a Low Path strain of H5N1 was found on a Michigan poultry farm in 2002. At that time Michigan's State Veterinarian recommended the poultry flock be humanely destroyed as a safety precaution."

Low-Pathogenicity H5N1 vs. High-Pathogenicity H5N1
http://www.usda.gov/wps/portal/!ut/p/_s.7_0_A/7_0_1OB?contentidonly=true&contentid=2006/06/0224.xml
 

 
June 2006
There are two types of avian influenza (AI) that are both identified as H5N1. A difference exists in the virus classification; one is low-pathogenicity (LPAI) and the other is high-pathogenicity (HPAI). Pathogenicity refers to the ability of the virus to produce disease.
HPAI H5N1, often referred to as the "Asian" H5N1, is the type causing worldwide concern. LPAI H5N1, often referred to as the "North American" H5N1, is less concerning. Following is an explanation of the differences between them.
 
LPAI H5N1 ("North American" H5N1)
LPAI, or "low path" AI, naturally occurs in wild birds and can spread to domestic birds. In most cases, it causes minor symptoms. It is rarely fatal in birds. These strains of the virus are not a human health concern. This includes LPAI H5N1.
 
Evidence of LPAI H5N1 has been found on two occasions in wild birds in the United States in recent years. In 1975, LPAI H5N1 was detected in a wild duck and in 1986, it was detected in a wild mallard. These detections occurred as part of routine sampling, not as a result of noticeable illness in the birds. These LPAI H5N1 strains are not closely related to the more severe HPAI H5N1 circulating overseas.
 
HPAI H5N1 ("Asian" H5N1)
HPAI, or "high path" AI, spreads rapidly and is often fatal to chickens and turkeys. This includes HPAI H5N1. Millions of birds have died in countries where HPAI H5N1 has been detected. This virus has also infected people, most of whom have had direct contact with infected birds.
HPAI H5N1 has not been detected in the United States. However, other strains of HPAI have been detected and eradicated three times in the United States: in 1924, 1983 and 2004. No significant human illness resulted from these outbreaks.
 
TERMINOLOGY
Avian influenza (AI)--the bird flu--is a virus that infects wild birds (such as ducks, gulls, and shorebirds) and domestic poultry (such as chickens, turkeys, ducks, and geese). There is flu for birds just as there is for humans and, as with people, some forms of the flu in birds are worse than others.
 
AI viruses are classified by a combination of two groups of proteins: the hemagglutinin or H proteins, of which there are 16 (H1-H16), and neuraminidase or N proteins, of which there are 9 (N1-N9).
 
Pathogenicity: the ability of the virus to produce disease. AI strains also are divided into two groups based upon the ability of the virus to produce disease: low pathogenic (LP) and highly pathogenic (HP).
 
Low Pathogenic or "low path" avian influenza (LPAI): LPAI occurs naturally in wild birds and can spread to domestic birds. In most cases it causes no signs of infection or only minor symptoms in birds. These strains of the disease pose little significant threat to human health. These strains are common in the U.S. and around the world.
 
Highly Pathogenic or "high path" avian influenza (HPAI): HPAI is often fatal in chickens and turkeys. HPAI spreads rapidly and has a high death rate in birds than LPAI. HPAI has been detected and eradicated three times in U.S. domestic poultry. HPAI H5N1 is the subtype rapidly spreading in some parts of the world.

CONFIRMATORY TESTS BEING CONDUCTED ON MICHIGAN WILD BIRD SAMPLES

WASHINGTON, August, 14, 2006-The U.S. Departments of Agriculture and Interior today announced that routine surveillance has indicated the presence of H5 and N1 avian influenza subtypes in samples from two wild mute swans in Michigan, but testing has ruled out the possibility of this being the highly pathogenic H5N1 strain that has spread through birds in Asia, Europe and Africa. Test results thus far indicate this is low pathogenicity avian influenza, which poses no threat to human health.

The swans were sampled as part of the expanded avian influenza surveillance program. They were showing no signs of sickness, which suggests that this is low pathogenicity avian influenza. Additionally, genetic analysis of the virus conducted at USDA's National Veterinary Services laboratories (NVSL) in Ames, Iowa, suggests that it is similar to a low pathogenicity strain that has been found in North America.

It is possible that these birds were not infected with an H5N1 strain, but instead with two separate avian influenza viruses, one containing H5 and the other containing N1. The confirmatory testing underway at NVSL will clarify whether one or more strains of the virus are present, the specific subtype, as well as pathogenicity. These results are expected within two weeks and will be made public when completed. It should be noted that wild birds are known to harbor many influenza viruses, and the finding of one or more of these viruses during routine testing is not unusual.

The swans were sampled August 8 at the Mouillee state game area located on the coast of Lake Erie in Monroe County, Michigan. The samples were taken by USDA Animal and Plant Health Inspection Service personnel as part of an expanded wild bird monitoring program. The Departments of Agriculture and Interior are working collaboratively with States to sample wild birds throughout the United States for the presence of highly pathogenic avian influenza.

Initial screening tests on the swan samples were conducted by Michigan State University's Diagnostic Center for Population and Animal Health--part of USDA's National Animal Health Laboratory Network. These tests indicated the presence of an H5 avian influenza virus. Confirmatory testing at NVSL confirmed the H5 and the N1. This testing also suggests, but has not yet confirmed, that this is low pathogenicity avian influenza.

Low pathogenicity avian influenza (LPAI) commonly occurs in wild birds, where it typically causes only minor symptoms or no noticeable symptoms. These strains of the virus are not a human health concern. This includes LPAI H5N1, commonly referred to as the North American H5N1. This strain of low pathogenicity avian influenza is very different from the more severe HPAI H5N1 circulating overseas, which is commonly referred to as the Asian H5N1.

Evidence of LPAI H5N1 has been found on two occasions in wild birds in the United States. In 1975 and 1986, it was detected in wild ducks. These detections occurred as part of routine sampling. LPAI H5N1 has also been detected in Canada, most recently in 2005.

I fibbedEmbarrassed One more article - just because it is a local report out of Michigan.
 
 
Article published Aug 14, 2006
BREAKING NEWS:
Pointe Mouillee swans checked for bird flu strain


Two mute swans found in Monroe County have a virus related to the bird flu that has swept parts of Asia, but officials don't believe the discovery represents any threat to human health.

The birds were two among 20 that were sampled at the Pointe Mouillee State Game Area last week. Further testing is under way, but the virus found is believed to be a low pathogenic strain "and not known to produce any illness in people," said Dr. Ron DeHaven, a United States Department of Agriculture administrator.

"This is not the virus found in Asia or other parts of the world - that we can say for certain," Dr. DeHaven said.

A highly pathogenic version of the H5N1 strain resulted in the deaths of millions of birds and hundreds of people in parts of China and Asia.

Dr. DeHaven also said the strain carried by the Pointe Mouillee swans is believed to be that found in the United States in 1975 and in Manitoba, Canada, last year and is not known to produce illness in people.

Federal and state officials have stepped up their waterfowl monitoring programs since the Asian bird flu scare in hopes of finding early evidence of the disease if it migrates to this country. They discussed the Pointe Mouillee swan discovery during a press conference this morning because the H5 strains can mutate rapidly.

But Dr. DeHaven said there's no evidence yet that the virus found is a threat to poultry.

"The finding of this virus in wild birds should be no basis for any country imposing trade restrictions," he said.

He said the virus was found in genetic tests on birds taken during a thinning of the mute swan population at Pointe Mouillee. It was pinpointed at a screening lab at Michigan State University, and the swans with the virus now are undergoing more tests at the National Veterinary Services Laboratory in Ames, Iowa.

The plan there is to inoculate eight chicks with the swan virus. If six or more die within 10 days, the strain might be categorized as a high pathogenic virus. The results might be known in two weeks.

Meantime, he said there's no cause for health officials to take any steps in response to the discovery.

Pointe Mouillee, in Berlin Township on the Lake Erie shore, is a 3,000-acre marsh that's part of the migratory path for waterfowl, birds of prey, songbirds and about 75,000 shorebirds.

Part of the National Response Plan is to send all suspected H5N1 birds for testing in Ames.  They are currently testing for High Path in Ames.

Meantime, he said there's no cause for health officials to take any steps in response to the discovery.

Pointe Mouillee, in Berlin Township on the Lake Erie shore, is a 3,000-acre marsh that's part of the migratory path for waterfowl, birds of prey, songbirds and about 75,000 shorebirds.

DESCRIPTION
Scientists have discovered the possible presence of bird flu in the United States -- in wild swans near the banks of Lake Erie -- but it does not appear to be the worrisome strain that the government has long feared. Routine tests on two seemingly healthy wild mute swans in Michigan suggest they might have the H5N1 virus; confirmatory tests are under way. But other testing has ruled out that it could the so-called highly pathogenic version of that virus that has ravaged poultry in Asia, and killed at least 138 people worldwide, the Agriculture Department announced Monday. "This is not the highly pathogenic avian influence virus that has spread through much of other parts of the world," said Ron DeHaven, administrator of USDA's Animal and Plant Health Inspection Service. "We do not believe this virus represents a risk to human health," he declared.

To some extent, I'm getting mixed signals from these reports today. They say that the H5N1 is not high-path, yet they are doing more tests to verify. However, in the same report they say that they have ruled out H5N1 high path. Which is it? If it takes two weeks to conduct the tests, have they not completed those tests yet.

LPAI viruses have the potential to evolve into HPAI viruses and this has been documented in some poultry outbreaks.

I didn't see/read the news briefing so cannot determine the tone of how all this was presented, but a big question I have is why is there a briefing about this low-path version, which has been in the U.S. before?  Why do we need to be briefed about something that poses no threat to humans or birds?  With everything in the world going on this seems strange unless they already know it is high path or seem to think there is a good chance the follow up tests could show it ... someone please talk me thru this, I can;t get it out of my mind why they would brief on something innnocuous unless they are trying to break this to us gently in stages.Confused

Well, to clarify, this was the general daily white house briefing with the press.  They primarily covered Isreal and Lebanon.   The briefing was definately not strictly related to Michigan.
 
Tony Snow just kind of threw it out there as in  Oh, by the way, you'll be hearing about this soon in the news and there will be an Ag briefing in a moment on the subject .
 
He didn't say anything else about it that I saw, but I was in and out of the room so not for sure on that.
 
As for what it means, not sure, but am glad they are keeping us informed.

Does anybody else find it odd that the determination of High path will be made by the death of 6/10 chicks or a 60% mortality? 
 
Truly I don't know anything about the virus in birds.  I must assume that they are making reasonable choices.  It just seems like the death of 5/10 chicks would also be significant...

So there is HPAI and LPAI with from what I can tell a very generalized description.
 
Exactly what in terms of Verolgy Testing would determine the difference, does anyone know????? 
 
Or are they just clueless and waiting for birds to die before thaey say its HPAI.
 
Does anyone one know the exact location where the birds were tested?????

Transcript of USDA and DOI Avian Influenza Media Briefing August 14, 2006 - Washington, D.C.

MS. TERRI TEUBER: Good morning, everyone. This morning we'd like to provide an update on the Wild Bird Monitoring Program being conducted as an interagency project. With us today to offer some comments are Dr. Ron DeHaven, the administrator of the U.S. Department of Agriculture Animal and Plant Health Inspection Service; Dr. Sue Haseltine, associate director for Biology at the U.S. Department of the Interior, the U.S. Geological Survey; and Dr. Bill Raub, science advisor to the Secretary at the U.S. Department of Health and Human Services.

If you'd like spelling on any of those names, I'd be happy to assist you with those afterwards.

And with that, I'm going to turn it over to Dr. Ron DeHaven.

DR. RON DEHAVEN: Thank you, Terri. Routine surveillance testing has indicated the possible presence of H5N1 avian influenza subtypes in wild mute swans in the state of Michigan. Testing has ruled out the possibility that this is the highly pathogenic H5N1 virus that has spread through much of Asia, Europe and Africa. And I want to repeat that. This is not the highly pathogenic avian influenza virus that has spread through much of other parts of the world.

Further, we do not believe that this virus represents a risk to human health.

Genetic analysis of this particular virus indicates that it's similar to low pathogenic H5N1 avian influenza strains that have been found previously in North America. The fact that these swans showed no signs of sickness and there was no sign of disease in birds around them further suggests that we are dealing with a low pathogenic avian influenza virus.

Final confirmation of its pathogenicity will be made and reported when that testing is completed.

Let me explain that pathogenicity simply refers to the ability of a virus to produce disease. Thus, a low-pathogenic virus produces much less disease and mortality in birds that are affected than highly pathogenic viruses would.

Low pathogenic strains of the virus furthermore typically are of no human health concern, and this would include the low pathogenic H5N1 virus that has been found in wild birds previously in North America.

In fact there's another possibility with regard to this particular situation, and that is that these birds are not infected with an H5N1 virus at all; but instead they could be infected with two separate avian influenza viruses, one contributing the H5 component and the second virus contributing the N1 component. Further testing will determine whether or not that is the case.

Even if that is the case, this would not change our assessment relative to the low risk associated with this particular finding. These mute swans were resident wild birds, not migratory birds, and we have no reason to believe those birds that were positive had any connection with any commercial poultry. Again, these were wild birds, and we have no reason to believe that any commercial poultry have been exposed to these particular swans.

Confirmatory testing is continuing at the U.S. Department of Agriculture's National Veterinary Services Laboratories in Ames, Iowa, and this testing will determine the exact subtypes of the virus and confirm its pathogenicity, whether it's a highly pathogenic or a low pathogenic virus.

These results are expected within two weeks time, and we will make them public when they become available.

We are providing information about the sampling even though there is little reason for concern because of our commitment to transparency in the testing process.

I may also take this opportunity to give some background on avian influenza viruses in general. AI viruses are in the same family of viruses that produce flu in humans every year. AI viruses can infect chickens, turkeys, pheasants, quail, ducks, geese, guinea fowl, as well as a number of other birds including wild migratory fowl.

Worldwide there are literally hundreds of avian influenza viruses, each of which can produce varying degrees of illness in poultry. We typically characterize these viruses based on two proteins that are found on the surface of the virus. One is referred to as a hemagglutinin protein or H protein, and the other a neuraminidase or simply N protein.

There are 16 different H subtypes, 9 different N subtypes; so you have a combination of 144 different characterizations of this virus based on the particular H and N types.

The virus that's currently circulating in much of the rest of the world -- that is in fact highly pathogenic in poultry and is capable of producing disease in humans -- is by this characterization an H5N1 highly pathogenic virus. But I think it's important to point out that viruses within that same subtyping can be very different. So, for example, you can have two distinctly different H7N2 viruses, and as is the case with the H5N1 we have two distinctly different H5N1 viruses -- the highly pathogenic form that is producing disease in poultry and in some cases in humans in much of the rest of the world, and this North American H5N1 virus that heretofore has been low pathogenic in birds and is not known to produce any disease in people.

So not all viruses are created equal, even those that would have the same characterization such as an H5N1 are not always the same.

Because of increased disease surveillance testing that we are doing in wild birds in the United States, and given the number of avian influenza viruses out there, it is certainly not unexpected that we would find a number of low-pathogenic avian influenza viruses including an H5N1 virus that we know has been circulating before in wild birds in North America. In fact, this low-pathogenic H5N1 virus has been found on two occasions in wild birds in North America. These were in wild ducks in the U.S. in 1975, and 1986, and more recently late last year in Manitoba, Canada.

I should point out too that according to the International Standards put out by the OIE, or the World Organization for Animal Health, finding of this virus in wild birds should be no basis for any country imposing trade restrictions on the United States and our commercial poultry.

A little bit of additional information about this particular Michigan situation-- the samples in question were collected as part of our routine surveillance program on Tuesday, August 8, and they were collected by some our Wildlife Services employees within the Animal and Plant Health Inspection Service of USDA. The samples were collected at Point Mouillee, which is a game area in Monroe County, Michigan, which is found in the southeastern tip of the state of Michigan.

Screening tests on these samples were conducted at the Diagnostic Center for Population Animal Health at Michigan State University on August 9, and when they came back with positive results for H5 those samples were then forwarded to our National Veterinary Services Laboratories in Ames, Iowa, where confirmatory testing began on August 12.

It was those screening tests originally conducted at the laboratory at Michigan State University that indicated that these birds had been exposed to H5 avian influenza viruses.

With that, let me turn the microphone over to Dr. Sue Haseltine from the U.S. Geological Survey at Department of Interior where she is the associate director for Biology, to give an Interior perspective on this situation. Sue?

DR. SUE HASELTINE: Well, thanks, Ron, and good morning, everyone. I guess from Interior's perspective I'd like to bring you up to date a little bit on the sampling that we're doing in wild birds across the country for avian influenza. As Ron has said, this finding of an H5N1 is not a surprising event to us even though it's in a wildlife species of a resident mute swan. And in fact we have been increasing our surveillance for all avian influenza subtypes throughout wildlife species in this country as sort of an early warning system for this particular strain in Asia.

And just to give you a sampling of that, in Interior we have tested so far over 8,000 samples from migratory birds in this country since early June. About 4,000 of those are from subsistence hunters in Alaska-- the subsistence hunt in the spring harvests all kinds of migratory birds as they return from their wintering grounds to breed, many of them from Asia. And then about 4,000 additional samples have been run on live birds that we know have a life history of spending time in Asia during the wintering months of their life cycle.

In that sampling as a whole, we found less than 2 percent of them to have contained avian influenza viruses of any subtype, and that's about standard for what we would find sampling wildlife species across the country. We tend to find a bimodal distribution in avian influenza viruses. They tend to build up and we find more when we sample in the fall.

But we're about on point, and we are continuing to sample both live birds as they return, especially to the Pacific Flyway and the Pacific Islands, and as I said the spring subsistence hunt.

We've also increased our capability to detect mortality events around the country, and Interior as a whole has responded to about 18 large-scale wildlife mortality events since early June, and none of those have been caused by avian influenza. But that's another increased surveillance that we, and the states, are all looking out for.

DR. DEHAVEN: Thank you, Sue. I think this points out an important thing. It is certainly no surprise that we're here this morning given the level of surveillance that we're doing in wild birds and knowing what we know about the prevalence of avian influenza in those species. It's really not surprising that we have found this particular virus. Certainly we will continue the testing that would be relevant in terms of characterization of this virus. But again the fact that we're here this morning reporting this is certainly no surprise given the volume of testing that we're doing as part of our overall highly pathogenic AI program in the U.S.

And I have to say, too, that it is, I think, a model of cooperation in that some of the testing is being carried out by Department of Interior, some by Department of Agriculture, and much of it by our colleagues in the State Departments of Natural Resources and Game and Fish.

With that, let me turn the microphone over to Dr. Bill Raub who's the science advisor to the Secretary of Health and Human Services for a human health perspective. Bill?

DR. BILL RAUB: Thank you, Ron. I appreciate the opportunity to join you this morning. I reinforce Dr. DeHaven's point that the evidence accumulating here suggests no threat to human health. We see no cause for public health and medical authorities to take any special actions as a result of this information.

We are dealing by all evidence with a matter of wildlife biology. From the perspective of Health and Human Services, we very much appreciate the initiatives of our colleagues in the Department of Agriculture and the Department of Interior for mounting and operating this wildlife surveillance activity.

We appreciate our partnership with them. The response here demonstrates the smooth and effective capabilities and coordination amongst the agencies and augers well should there be the time when a somewhat more troublesome set of information emerges than we have as of now.

All of our agencies have offered a variety of general precautions with respect to such things as dealing with sick and dying animals, which is not the case here; precautions with respect to workplace exposures such as in handling sick and dying animals, which is not the case here but we remain vigilant and prepared.

And again, I appreciate the initiative of our two colleague cabinet departments. Thank you.

DR. DEHAVEN: With that we would like to open it up for your questions and would only ask that you get a microphone before you ask your question.

REPORTER: Dr. DeHaven, Bill Tomson, Dow Jones. You've said before, and correct me if I'm wrong, that low-path can evolve into high path. Is that the case here? Is this something you're concerned about this evolving into a highly pathogenic strain?

DR. DEHAVEN: One of the characteristics about influenza viruses in general is their ability to mutate and mutate quickly, and it's really for that reason that the flu shot that you obtained last year won't protect you from the flu viruses that we'll encounter next year or the year after. It's no different in birds. In fact, these viruses do mutate quickly.

It's only the H5 and H7 subtypes, low pathogenic H5 and H7 subtypes, that have ever been known to mutate into a highly pathogenic form. So the fact that we are dealing here with what looks like a low pathogenic H5 virus would be reason for concern simply because any H5 or H7 virus has that potential.

But let me emphasize again the fact that there is no known exposure of these birds to commercial poultry, and we also know that again wild bird populations have a number of different avian influenza viruses out there. So this is no surprise. We've known that there's been an H5N1 low-pathogenic virus circulating in wild birds in this country for a number of years. So not a surprise. But again, any H5 or H7 virus is of concern from a commercial standpoint in that it has the potential to mutate to a highly pathogenic form.

In the back?

REPORTER: Irv Chapman. I work for Bloomberg. First a factual question. We heard that 8,000 birds have been tested by Interior. Is there an overall number for how many birds have been tested this season and nationwide?

And second, how did this particular swan get the virus or get sick -- or if it's not sick, just get the virus?

DR. DEHAVEN: Let me take the second question first in terms of how this bird might have gotten the virus and its clinical symptoms and turn over to Dr. Haseltine to talk about the numbers of testing.

Again I think it's important to emphasize that these avian influenza viruses are in our wild population. In fact wild birds serve as the reservoir, the ongoing source of virus for avian influenza viruses. So it's not surprising. And in some species of birds the birds are completely healthy and normal, as was the case here. These birds were sampled as part of our routine surveillance program. There was no morbidity or mortality associated with these birds at the time that they were tested.

So what we have are healthy, normal-appearing birds that appear to have been carrying a low pathogenic virus as best we can tell at this point in time.

I mentioned that the cooperative effort between Department of Interior and USDA in carrying out this wild bird surveillance program, Dr. Haseltine mentioned some 8,000 samples collected thus far by Department of Interior-- our USDA APHIS Wildlife Services colleagues thus far have collected in the neighborhood of 2,000 to 3,000 samples. But let me defer to Sue for some more definitive information.

DR. HASELTINE: I think the answer is, we can't really tell in the samples yet because in addition to federal efforts there are also state efforts and university efforts going on. And I guess this would be a good time to put a plug in for our joint information systems, which are being prototyped at the moment. And by this fall, we have a commitment from the whole community to deposit their information in those. And we should, in a much more rapid way by September or October, be able to give you a total that have been tested and where those are. But I'm sorry I can't do that right now.

DR. DEHAVEN: It's important to point out too that while we've been doing a lot of testing in Alaska, because those are the nesting and breeding grounds where these birds are now, we'll be doing a lot of testing in the lower 48 throughout the United States beginning in late August through September and the fall migration season. So much of the testing in the rest of the country will begin late August and continue on through the fall.

Yes, ma'am?

REPORTER: Salli Kidd with Hearst TV. What is happening with the birds that tested positive? Are you destroying them?

DR. DEHAVEN: We actually -- it's a unique situation with these particular mute swans in that they are a species of swan that was introduced in the area and as Dr. Haseltine pointed out they are actually residents in this game area in Monroe County. Because of the overpopulation of mute swans and because of the fact that they compete better than some of the native species of birds -- for example the trumpeter swan as well as loons -- we actually had a contract in APHIS with the Michigan Department of Natural Resources to decrease the population of these particular species of birds.

So the animals that were tested were actually part of that reduction in population effort, and we're just taking good advantage of that fact in collecting samples from those birds that are being sacrificed. So these birds in fact were sacrificed and then samples collected from them. Again, there are many more of these species, these mute swans, in that game area. And there is no evidence of any mortality or morbidity, no sickness or dying in that population of birds.

Yes, sir -- gentleman in the yellow shirt?

REPORTER: -- Bridges, Associated Press. Could you explain a little bit the scene, what other bird species are present in this preserve? Have you stepped up testing of those species? Numbers of birds that are there? And also, what might have been the source of the virus? Was it something, was it indeed a reservoir? Is it something that may have recently arrived carried by migratory birds? Just if you could explain a little bit the mechanics.

DR. DEHAVEN: Let me ask Dr. Haseltine to take that.

DR. HASELTINE: Well, I can only give you a general answer to that question. I don't know the specifics. But you know mute swans are a wetlands species as they are around here, so you would expect to have shore birds, waterfowl, and it's a semi-forested area so raptures and passerine birds in the area.

As far as how the virus might have gotten there, as Dr. DeHaven said we've found this virus, this particular strain of the virus, in several other wetlands situations around the U.S. and Canada over the last 20 years, and no doubt this virus is cycled through feces and what not. So that would be my best guess as to how these particular birds picked it up.

REPORTER: To follow up, wouldn't this maybe establish a precedent for the high path mode where it could have made it to these shores? Or as you suggested is it something that perhaps has been present in the background?

DR. HASELTINE: I think it's present in the background in this country and in Canada and cycles -- you know mute swans are an introduced species that while they tend to be fairly resident they move back and forth with weather fronts in open water and all kinds of migratory species then use the same wetlands that they do. So it makes sense to me that this is not a precedent. It's just a normal avian influenza event.

DR. DEHAVEN: Let me clarify with three points. One, we can definitively say this is not the H5N1 virus, highly pathogenic virus that's been found in Asia and other parts of the world. That we know for certain, so it's not the introduction of that virus into North America.

Secondly, we do have reports of a number of different species of birds in this game area, various species of ducks, loons, other types of swans. So there's a number of different species.

And the third point is that we will be coordinating with the Michigan Department of Natural Resources to do additional testing in those species of birds in this particular game area.

But again, not surprising that we would find avian influenza viruses in our native population of wild birds. We know they are the reservoir, and we also know that there's been a low pathogenic H5N1 virus circulating in North America. So here again no surprise that we just happened to find it in this particular area.

Gentleman in the blue shirt?

REPORTER: Scott Foster with NBC News. How many birds tested positive?

DR. DEHAVEN: The samples were collected from 20 birds and two of the 20 tested positive.

Next question? Next, ma'am.

REPORTER: Jane Zhang of the Wall Street Journal. The tests you are conducting in Iowa right now, are they going to be different from the ones you conducted in Michigan and the [inaudible]?

DR. DEHAVEN: There's a number of tests that we run on any of these samples. We have a network of over 50 laboratories, most of them state diagnostic laboratories, state veterinary diagnostic laboratories that are doing the screening test for us. They are doing what's called the PCR, polymerase chain reaction test, which looks for the genetic material of the virus. So that's a screening test that's being carried out at this laboratory at Michigan State as well as the other laboratories in our National Animal Health Laboratory network.

If any of those laboratories find an H5 or an H7 virus, again because of the potential for the H5 and H7 subtypes to mutate to a highly pathogenic virus, those samples then go to our National Reference Laboratory, which is the National Veterinary Services Laboratory in Ames, Iowa.

When samples are received there, as they were in this case, we repeat that PCR testing for H5 and H7. We also do a PCR testing to determine whether or not it's an N1 test. And so it's those two PCR tests conducted in Ames that show that we have the antigens compatible with an H5 and N1.

The additional testing that we're doing would include sequencing the genetic material. What is the sequence of the genes, and is that consistent with a North American strain or an Asian strain? The fact that this was compatible with our North American virus and not compatible with the Asian high path avian influenza virus that we are able to say that this is not the incursion of that Asian high path H5N1 virus.

There's also another test to determine pathogenicity or really two ways to determine pathogenicity. One is, looking at that sequence, that gene sequence. It's through that gene sequence testing that we're able to say that from a genetic standpoint this looks like a low pathogenic virus.

But the other test that we run involves inoculating baby chickens, eight baby chickens with this virus and then the test is that if six or more of those baby chickens die within a 10-day period then it would be characterized as a highly pathogenic virus.

So we're just starting that work. We have to grow more virus before we can inoculate it into the baby chickens. And so we're estimating it could take us upwards of two weeks before we would have that second test done that determines pathogenicity.

So two pathogenicity tests, one that looks at the gene sequence, one that looks at the impact on baby chickens. Either one or both that came back highly pathogenic, we would be bound to call this a highly pathogenic virus. The first test is done, indicates a low path virus. The results from that second test which should be forthcoming in the next two weeks.

Next question, please?

Very good. I see no other hands. We appreciate your time and attention. Again, we'll continue this testing that's being done on these samples, and as we get the additional results we'll certainly make them public to you.

Terri?

MS. TEUBER: I will just add that you should have packets that have both the news release about what has just been discussed, a fact sheet that compares low path H5N1 to high path H5N1. I know that's a little bit confusing, so hopefully that will help to clarify that. And also a fact sheet about our testing procedures because that too is somewhat complicated, and that sort of walks you through step-by-step what tests are conducted and where.

For those not present listening via telephone or on the web, all this information will also be posted on the USDA website.

Thanks everyone.

     I am glad that this incident was brought up at the the daily briefing.   Had they NOT mentioned it, there would no doubt be talk of 'cover-up and conspiracy' abounding.  Before rumors get out of hand, it's best to stand up and say, "Yes, this is what is going on.  We know many (some?) of you are concerned about AI (or any other potential pandemic situation) in light of what is happening in other parts of the world.  Here is what we have found so far..." 
     It is an uncomfortable truth to hear a reminder that any type of H5N1 is in the US but blissful ignorance will not aid in my (or your) preparations.   Sure wish Ed McMahon would pull through with that big check so I could prep in the manner to which I would like to become accustomed if need be.  You know, large propane tank, generators, independent wealth so I can move back to the old farm of childhood.  Alas, reality rears its head yet again.  At least I have wind-up flashlights and radios for comfort while I eat my pop top cans of beans and fruit.  Smile

I found this on-line and thought it was interesting.
 

Laboratory in Madison Testing Migratory Bird Samples for Bird Flu

May 25, 2006 : 12:00 AM
The US Geological Survey Lab in Madison, Wisconsin may be the first to know if the bird flu has hit the United Sates. They are testing fecal samples of migratory birds from the shoreline of the Alaskan coast. Many miratory birds use the Alaskan coast as an entry point to the country. The lab expects about 1300 samples to arrive over the next few days.

While other government labs are doing testing as well, the nature of the samples is such that the Wisconsin lab may the first to spot the disease. "If we find an H5 or H7 positive, it's been decided we will send it immediately to the National Veterinary Services Lab in Ames, Iowa," says Paul Slota. The Iowa lab will then confirm whether or not the virus has entered the country.

News of a positive test in Iowa would likely come out of Washington in a joint announcement from several government agencies.

From above comments_________________________________________________
 
In fact there's another possibility with regard to this particular situation, and that is that these birds are not infected with an H5N1 virus at all; but instead they could be infected with two separate avian influenza viruses, one contributing the H5 component and the second virus contributing the N1 component. Further testing will determine whether or not that is the case._______________________________________________________
 
WOW thats reassuring!!! Sounds like the testing used needs a major upgrade if you ask me. They dont know if its one or two virus samples in the results???? So what he is saying is it could be
H5N2
&
H7N1
and there test cant distinguish the difference?????
