So what is the East Anglia strain if not Uva Lake?

They are all Uva Lake, but slight different. The sequences from Romania form one Uva Lake branch, while Krosnodar and the three outbreaks from Germany form another. It sounds like the swans are on the Romania arm, while East Anglia is on the Germany/Krasnodar arm.

Weybridge hasn't released any of the Uva Lake sequences, including Kuwait, which was collected almost a year ago, so the England situation is based on DEFRA descriptions, but the published public sequences from Germany, Krasnodar, and Romania are quite clear.

Emergence of Uva Lake H5N1 in Europe

Recombinomics Commentary 19:29
January 15, 2008

The strain of the virus identified is very similar to that causing the cases confirmed in the Czech Republic, Romania and Poland mid to late last year. It is less similar to that found in East Anglia in November.

The above comments by DEFRA on H5N1 sequences from the mute swan infections in Dorset (see satellite map), indicate all H5N1 outbreaks in Europe since the summer of 2007 have been the Uva Lake strain (a sub-clade of clade 2.2.3). Sequences have been made public of outbreaks in late 2006 in South Korea, as well as 2007 outbreaks in Germany, Krasnodar (Russia), and Romania. Comments by FLI indicate the recent outbreaks in northeastern Germany are Uva Lake, and now comments by DEFRA indicate the outbreaks in Kuwait, Czech Republic, France, England, and Poland were also the Uva Lake sub-clade.

Therefore it is worth reviewing the emergence of the Uva Lake strain in Europe. In late 2005 and early 2006, the Qinghai strain of H5N1 was reported in approximately 50 countries west of China. The Qinghai strain has been designated Clade 2.2, and the strain was sub-divided into three additional sub-clades based on sequence data generated through the NIAID influenza sequencing project on samples provided by Ilaria Capua from Italy as described in Genome Analysis Linking Recent European and African Influenza (H5N1) Viruses. Clade 2.2.1 included isolates from Egypt, southern Germany, Italy, Mongolia, and some regions in sub-Sahara Africa. Clade 2.2.2 included isolates from northern Germany, Denmark, Sweden, Scotland, and Nigeria. Clade 2.2.3 included isolates from India, Afghanistan, Italy, and Iran.

The Uva Lake strain was isolated in wild birds in the summer of 2006 at Uva Lake, the largest lake in Mongolia. Although the outbreak was massive, killing thousands of wild birds, neither Mongolia nor Russia filed OIE reports. However, H5N1 was isolated in both countries and sequences from grebes and a duck in Tyva were published (see satellite map), as were sequences from a whooper swan and common golden eye from Mongolia. Although the sequences were clearly Clade 2.2.3, they were distinct from clade 2.2.3 sequences isolated elsewhere.

In the fall of 2006 South Korea reported an H5N1 outbreak, which was followed by an early 2007 outbreak in Japan. The sequences from the South Korean outbreak have now been published and they are closely related to the Uva Lake sequences. However, there were no reports of Uva Lake sequences to the west of Uva Lake in the latter half of 2006.

In early 2007 there was an H5N1 outbreak in Kuwait. Although it has been almost a year since that outbreak was reported, no sequences have been released. However, comments from DEFRA and Weybridge indicated the Kuwait sequences were 99.5% identical to sequences from a subsequent outbreak in the Czech Republic in the summer of 2007. The Czech outbreak was quickly followed by multiple wild bird outbreaks in Germany. FLI reports on those outbreaks indicated each outbreak (in Bavaria, Saxony, and Thuringen) was distinct, but most closely related to the sequences from Uva Lake. Recently these sequences were made public, confirming the close relationship. Outbreaks in Germany were followed by outbreaks in France, which was followed by an outbreak in Krasnodar in September.

Full sequences from all eight gene segments were quickly published from Krasnodar, and those sequences (from a chicken and whooper swan) were also closely related to Uva Lake. That outbreak was followed by the outbreak in free range turkeys in Suffolk, England. DEFRA comments indicated the H5N1 from that outbreak was related to the Czech sequences. Outbreaks were the reported at multiple locations in Poland, and as indicted by DEFRA, these were also related to Uva Lake.

Romania also reported an outbreak and quickly released HA sequences from three species (chicken, duck, and cat) and all three sequences were identical and closely related to Uva Lake, but distinct from the published sequences from Russia and Germany. FLI subsequently indicated the outbreak in northeastern Germany was also related to the earlier outbreaks in Germany. Comments haven?t been made on the sequences from Rostov, but the proximity to Krasnodar suggests the Rostov sequences are also Uva Lake related, which is also likely for sequences from Saudi Arabia and Pakistan.

Thus, it appears that the H5N1 emerging out of Qinghai Lake in China, Cheny Lake in Russia, and Erhel Lake in Mongolia in the summer of 2005 was repeated at Uva Lake in Mongolia in the summer of 2006. Like the earlier outbreak, detection of H5N1 was uncommon in the fall but was widely reported in the following year. Most of the reported outbreaks from the Qinghai strain were in early 2006. In early 2007 there were few reports of the Uva Lake strain, but reports became increasingly common beginning in the summer of 2007.

Although it is unclear what is circulating in Africa, the widespread outbreaks of the Uva Lake strain in the summer and fall of 2007 in Europe and the Middle East suggests reports of H5N1 in early 2008 will be common.

Fourth swan found with bird flu

A fourth swan at a swannery in Dorset has tested positive for the virulent H5N1 strain of bird flu, environment department Defra has said.

Three mute swans found dead last week at the Abbotsbury Swannery also tested positive for the strain of the disease.

Tests have been conducted on birds around the nearby Chesil Beach, as vets tried to contain the outbreak.

Culling has been ruled out so far but there are restrictions on movements of captive birds nearby.

Avian influenza update: further swan positive for H5N1<!-- #EndEditable --><!-- #BeginEditable "Body" -->
Following confirmation on Thursday 10th January of highly pathogenic H5N1 avian influenza in three swans in Dorset, Defra has today confirmed that another mute swan collected on 11 January as part of wild bird surveillance from the same area has tested positive for highly pathogenic H5N1 Avian Influenza.
There is currently no evidence to suggest widespread disease in the wild bird population, but enhanced surveillance is taking place and poultry keepers in the area are reminded to remain vigilant and report any signs of disease immediately. There is no evidence of disease in domestic birds.
<!-- #EndEditable --><!-- #BeginEditable "Editors" -->Further information <!-- #EndEditable -->

<!-- #BeginEditable "Notes" -->
  1. Information is available from the Defra Helpline (08459 33 55 77) - see www.defra.gov.uk for current opening hours. Bird keepers can also call the Animal Health recorded information line for the latest updates on 0844 884 4600.
  2. Avian Influenza is a disease of birds. While it can pass very rarely and with difficulty to humans, this usually requires extremely close contact with infected birds, particularly faeces. Advice from the Food Standards Agency remains that properly cooked poultry and poultry products, including eggs, are safe to eat.
  3. All Avian Influenza (H1 to H16) can be low pathogenic but only H5 and H7 are known to become highly pathogenic.
  4. Inside the Control Area and the Monitoring Area, the measures required by the EU Wild Bird Decision will be applied, including bird movements which will be restricted.
  5. All poultry keepers registered with the GB Poultry Register will be contacted by text message with updates. All poultry keepers responsible for a premises with 50 or more birds are legally required to register. Defra strongly encourages those with less than 50 birds to register voluntarily.
  6. The details on the measures that apply in the current zones can be found on the Defra website at www.defra.gov.uk/avianflu
  7. This is the second highly pathogenic H5N1 Avian Influenza case detected in a wild bird in the British Isles. The previous case was the swan found in Cellardyke, Fife in April 2006.
  8. Recent H5N1 cases in commercial poultry in Britain:
    November 2007 ? premises near Diss, Norfolk
    February 2007 ? premises in Upper Holton, Suffolk
    October 2005 ? quarantine premises in Essex

A fourth swan tests positive for bird flu



A fourth swan has tested positive for the H5N1 strain of bird flu, the Department for Environment, Food and Rural Affairs said yesterday.

Three other wild swans tested positive for the virus last week after they were found dead at the Abbotsbury Swannery in Dorset, an open reserve in the Chesil Beach area, during routine surveillance.

Restrictions on poultry movements in the area were imposed after the dead birds were confirmed to be infected with the deadly strain of bird flu last Thursday.

Defra said the infected mute swan had been collected on January 11 as part of wild bird surveillance in the area.

The Environment Department said ther e was currently no evidence to suggest the disease was widespread among wild birds in the area, but enhanced surveillance was taking place.

There is also no evidence of the disease in domestic birds, but poultry keepers are being urged to remain vigilant and report signs of disease immediately.

Control and monitoring zones were set up in the area after the first three birds tested positive for H5N1, with restrictions on moving poultry imposed within the zones.

Earlier this week two other dead swans found in the area tested negative for the deadly strain of bird flu.

John Houston, general manager at Abbotsbury Tourism, said: "This puts us back to square one in terms of waiting for a 21-day clearance before we are out of the woods.

"It's disappointing but not totally unexpected this early in the outbreak.

"It's going to take a while for it to be contained and weeded out."

The Department for Environment, Food and Rural Affairs (Defra) has said that this latest case follows three other wild swans testing positive for the virus after they were found dead at the Abbotsbury Swannery in Dorset, an open reserve in the Chesil Beach area, during routine surveillance.
Restrictions on poultry movements in the area were imposed after the dead birds were confirmed to be infected with the deadly strain of bird flu last Thursday.

This latest case is a further escalation and will worry officials as the virulent H5N1 strain has killed more than 200 people worldwide since 2003 and millions of birds had either died from it or been killed to prevent its spread.

However, Defra has set up control and monitoring areas around the premises where these latest bird fatalities were discovered.

Inside the areas bird keepers are required to house their birds and isolate them from contact with wild birds while bird shows and similar gatherings are banned.

Britain's first case of the deadly strain was in a wild swan found dead in Cellardyke in Scotland in 2006 and there have subsequently been outbreaks at poultry farms in eastern England, most recently last November.

H5N1 Confirmed in Fourth Swan in England

Recombinomics Commentary 11:11
January 17, 2008

A fourth swan has tested positive for the H5N1 strain of bird flu, the Department for Environment, Food and Rural Affairs said yesterday.

Defra said the infected mute swan had been collected on January 11 as part of wild bird surveillance in the area.

The Environment Department said there was currently no evidence to suggest the disease was widespread among wild birds in the area, but enhanced surveillance was taking place.

The above comments describe confirmation of a fourth H5N1 infected swan in the Dorset area (see satellite map). The earlier positives included swans collected in December, indicating infected swans have been detected over a two week period, which is evidence of widespread infection among wild birds.

Two of the positives were in swans that had been recent euthanized. One had a broken leg. Detection of H5N1 in live wild birds is rare, but these positives may have been linked to increased levels due to stress in the injured birds, coupled with collection procedures, which involved freezing the birds shortly after they were euthanized.

Prior to the recent four positives, the DEFRA surveillance program had detected H5N1 in a single wild bird, a whooper swan that washed up on the shores of Scotland in 2006.

Earlier media reports had suggested that the current outbreak in mute swans was due to a recent introduction. However, the failure to find wild bird sources for the H5N1 outbreak in free range turkeys in Suffolk, as well as H7N3 and H7N2 outbreaks in the same region in 2006 and 2007, signals caution in the interpretation of negative data generated by the surveillance program.

The H5N1 outbreaks in Germany, France, and the Czech Republic over the summer signaled increased activity in H5N1 in late 2007, early 2008 in Europe. England now has had two outbreaks, and sequence data indicates that the outbreaks are due to independent introductions of the Uva Lake strain. That strain has become dominant and accounts for 2007 outbreaks in the Czech Republic, Germany, France, Krasnodar, Romania, Poland, and probably Rostov.

Expanded testing of the mute swans in the region, including antibody testing, would be useful.

Fifth Swan Found With Bird Flu

A FIFTH dead swan has tested positive for the H5N1 strain of bird flu at a reserve, it was confirmed today.

Three other wild swans tested positive for the virus last week after they were found dead at the Abbotsbury Swannery in Dorset, an open reserve in the Chesil Beach area, during routine surveillance.

A fourth dead swan was confirmed to have tested positive yesterday.

John Houston, general manager at Abbotsbury Tourism Ltd, said today: ?One more swan has tested positive.

?We are expecting to have a run of positives and negatives while it works its way through the herd.?

Restrictions on poultry movements in the area were imposed after the dead birds were confirmed to be infected with the strain of bird flu last Thursday.

The Environment Department said there was currently no evidence to suggest the disease was widespread among wild birds in the area, but enhanced surveillance was taking place.

The Abbotsbury Swannery will be given the all-clear after 21 days with no birds testing positive for the virus.

TESTS have confirmed that a fifth swan at Abbotsbury had bird flu.

Two more swans have been found dead, bringing the total number of fatalities to 14 and the latest bodies have been sent off for tests.

The Department for the Environment, Food and Rural Affairs now plans to make random tests on some of the swans with the help of swanherds to check on their health.
