Re: LPAI Bird flu in Denmark (H7N1)
Bird flu returns
By The Copenhagen Post
<!--//artByline -->Published 29.04.08 00:00
<!--//artDato -->Over two thousand poultry birds will be put down on the island of Funen due to a new outbreak of bird flu
Around 2000 chickens and ducks from a farm on the island of Funen will be put down Wednesday after several of the birds were found to have contracted avian flu, reports Politiken newspaper.
The Danish Veterinary and Food Administration has indicated the virus is a mild strain and not the deadly H5N1, which hit Denmark in 2006. That outbreak resulted in the death and destruction of thousands of birds and was found in numerous species.
DVFA has instituted a quarantine at a one-kilometre radius around the Funen farm, meaning that no movement of poultry in and out of the zone is allowed without the administration's approval. The quarantine is expected to last at least two weeks.
Officials say there is no danger for humans to contract the virus. This latest outbreak is the fourth instance of 'low-pathogen' avian flu in Denmark. (RC)

[EXCERPTS FROM EUROPEAN CENTRE OF DISEASES PREVENTION AND CONTROL, INFLUENZA NEWS - http://www.ecdc.europa.eu/ ]
(1b) AVIAN INFLUENZA ? ANIMAL HEALTH ? DENMARK
29TH April 2008
Low pathogenic avian influenza virus (serotype H7) has been isolated in poultry farm with 300 geese, 250 ducks and 1500 mallards in Denmark.
Geese and ducks were tested in accordance with the Danish surveillance programme for avian influenza in poultry.
The Danish Veterinary and Food Administration has set up a restricted zone around the holding and is implementing the necessary measures in accordance with the European Union Directive 2005/94/EC (See OIE report).
The poultry outbreak detected in Denmark, is caused by one of the many Low Pathogenicity Avian Influenzas (LPAIs) viruses that are circulating among birds.
Outbreaks of LPAIs in birds, both wild and domestic poultry, occur regularly in Europe and are probably more common than recognised.
LPAIs can be occasionally transmitted to humans, but in most of the cases they have only been associated with mild to moderate self-limiting disease, primarily conjunctivitis or flu like illness (1).
An ECDC assessment carried out in 2007 concluded that there is only limited public health risk from LPAIs outbreaks, however those who are at risk should maintain vigilance and take precautions (2).
The risk of infection with LPAIs is almost entirely confined to people who have close contact with domestic poultry (chickens, ducks etc) or their droppings.
Occasionally, it seems that an LPAI transforms in birds to become a high pathogenicity avian influenza (HPAI) strain, but that is thought to be a rare event.

> 300 geese, 250 ducks and 1500 mallards
weird. No chickens.
Remember all the pictures and videos and comments about chickens.I'm interested in expert panflu damage estimates

Re: LPAI Bird flu in Denmark (H7N1)
Denmark released several full H5N1-genomes before and
seasonal human genomes recently with a paper:

Re: LPAI Bird flu in Denmark (H7N1)
the same farm had an outbreak in 2006 (with another owner):
Funen County 2 June LPAI H5N2 19750 mallard ducklings 1606 goslings 1599 domestic ducklings
has a good summary of H5N1 in Denmark 2006
44 wild birds with H5N1 in Denmark 2006/03/14-2006/05/29
1120 dead 10 other animals examined,1112 droppings
ducks (60%
, swans (16%), birds of prey (18%), crows (2%) other waterfowl (4%) with H5N1
a back-yard flock was found infected with HPAI H5N1 on 18 May 2006.I'm interested in expert panflu damage estimates

Over 2.000 hens and ducks have on Tuesday morning to be fought to death for a "safety's fault".
That explains veterinary-manager in Fødevarestyrelsen, Jan Mousing.
Therefore be fought the herd on over 2.000 poultry to death, just as the authorities import a safety zone on 1 kilometre around the farm.
The zone concerns Sikkerhedszonen in some weeks - that officially is called a prohibited area - mean that the removal with poultry must only happen with the goods region's permission and that transit is only allowed without reading or stoppings on the way.
In addition to arrange cattle shows and illegal to postpone poultry. it is.
Jan Mousing reports that the prohibited area will exist in some weeks.
"The find is an example that our surveillance works", he says.
Outbreaks aren't dangerously the authorities have earlier today managed to confirm that there has broken out avian flu on a Funen farm near Stenstrup, but it's of the non-threatened type "H5N7".
It's fourth time that' low-patogenic avian influenza', as if it's called, are found in Denmark.
"We side an eye with it, because the influenza can spread and stay dangerous", Jan Mousing says.
It happens, if the non-threatened [HPAI] influenza type is mixed with another type, which is dangerous, because there saw can put a mutation out of it.
The exports leave free you earlier outbreaks of avian flu in Denmark, where only one has been of the serious kind, have been important for the exports abroad.
But Jan Mousing doesn't expect that the current find will mean something special.
"There may be a few markets, but we aren't worried for it", Jan Mousing says.-------Comment

Re: LPAI Bird flu in Denmark (H7N1)
I do not think H5N7 is a typo.
The Danish text says: "den ikke-farlige type 'H5N7'"
means: "the not dangerous type 'H5N7"'
.
In 2003 H5N7 was discovered for the first time ever. Discovered in ducks in Denmark.

OIE report says H7 :
geese and ducks, not chickens.

Its not a typo. Its just mainstream media attempts at science. Scientific background of mainstream media writers usually needs some work.Originally posted by Dutchy View PostComment
