LPAI Bird flu in Denmark (H7N1)

Bird flu detected in Denmark

By Zo? Casey

First bird-flu alert since January does not involve the strain deadly to humans.

The Danish food and veterinary ministry has confirmed that bird flu has been detected on a farm in southern Denmark, prompting it to cull nearly 2,000 birds on 29 April.

However, the ministry stressed that the bird-flu strain found was H7N1, a low pathogenic strain, and not the H5N1 virus, which can kill humans.

The disease was detected a routine, annual check carried out by Danish veterinary authorities. The infected birds showed no outward clinical symptoms of the H7N1 flu virus, but laboratory tests revealed the birds had the disease, the spokesperson said. In all, 300 geese and 250 ducks at the farm will be killed, as well as around 1500 wild mallard.

The ministry has also created a restricted zone within a radius of one kilometre of the farm. Under EU rules set up to control bird flu, the zone will be sealed off for four weeks. No markets or farm shows can take place during this period.

The farm is located in a very rural area, on Fyn Island, and its main business is breeding birds to re-stock wild-bird populations for hunting purposes. The ministry believes the nature of the business will limit the chances of the disease spreading into the wild-bird population and into the human food chain.

Fears of a bird-flu pandemic appear to have calmed in European media over the past year. A knock-on effect has been an improvement in consumers' confidence about buying poultry. For example, the Irish food board, Bord Bia, reported that production rose by 3% in 2007 and exports totaled ?253 million, up 5% on 2006.

The last outbreak of bird flu in the EU concerned wild swans in southern England on 10 January. Three swans were infected with the H5N1 virus, but the disease did not spread. However, in November 2007 some 6,500 turkeys, geese and ducks were slaughtered at a poultry farm on the Norfolk/Suffolk border in England after H5N1 was found.

Over the past two years, H5N1 has been detected in Austria, the Czech Republic, France, Germany, Greece, Hungary, Italy, Poland, Slovakia, Slovenia, and Sweden as well as Denmark and the UK.

Perhpas, dr Niman, this is a wishful thinking. A certain number of countries don't release Immediate Notification Report to OIE (or by OIE) but only cumulative reports (ie: every six months). This is the case of Italy. The most recent epizootics by LPAI A/H5 and A/H7 was discovered early in february this year, but no OIE reports or media coverage. One must go on EU commission website and search into to learn more about italian situation (ie: ADNS reports).:confused:

Yes, some countries are more responsive than others. High path gets more attention, but in this case Denmark promptly reported low path H7N1. Other countries, such as Indonesia, are quite delinquent, even with high path H5N1 producing fatal infections in its citizens (the last OIE report by Indonesia was in Sept, 2006).

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):tiphat: http://jp.dk/uknews/article1330577.ece

[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.

weird. No chickens.
Remember all the pictures and videos and comments about chickens.

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

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.

Which strain was it really yet? H7N1 or H5N7??

The authorities import safety zone Fødevarechef emphasizes that it's the non-threatened type of avian flu, which is found on a farm in Funen.​


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.​

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.

Its not a typo. Its just mainstream media attempts at science. Scientific background of mainstream media writers usually needs some work.
