Wonder if it is H5N8 which has been found in Germany on 6 the November and yesterday in Holland ? At least they have ruled out H5N1.

A case of bird flu has been confirmed at a duck breeding farm in East Yorkshire, officials have said.

The Department for Environment, Food and Rural Affairs (Defra) said the risk to public health was very low. A cull of poultry is being carried out at the site and an exclusion zone is in place.

The strain has not been confirmed, but the deadly H5N1 form has been ruled out by Defra officials.

The case is the first in the UK since 2008.

The exclusion zone around the Yorkshire farm will prevent all poultry and poultry waste being transferred in or out of the area. Some 6,000 ducks will be culled.

"We are taking immediate and robust action which includes introducing a 10km restriction zone and culling all poultry on the farm to prevent any potential spread of infection. A detailed investigation is ongoing.

"We have a strong track record of controlling and eliminating previous outbreaks of avian flu in the UK."

Bird Flu Outbreak At Duck Farm In Yorkshire

There is at least one confirmed case of the virus at the stricken farm as a six-mile restriction zone is put in place in the area.

A case of avian flu has been confirmed on a duck breeding farm in East Yorkshire, the Department for Environment, Food and Rural Affairs has said.

Defra said there is at least one case of the virus at the farm in the Driffield area - but insisted the risk to public health is "very low".

It confirmed the entire flock - about 6,000 ducks - would be culled as a result.

A Defra spokesperson said: "We have confirmed a case of avian flu on a duck breeding farm in Yorkshire - the public health risk is very low and there is no risk to the food chain.

"We are taking immediate and robust action which includes introducing a 10km (6 mile) restriction zone and culling all poultry on the farm to prevent any potential spread of infection.

"A detailed investigation is ongoing. We have a strong track record of controlling and eliminating previous outbreaks of avian flu in the UK."

Bird flu, or avian flu, is an infectious viral illness that spreads among birds. In rare cases it can affect humans.

There are 16 different avian flu types. The H5N1 strain is the one that causes the most concern because it is the most virulent and deadliest.

H5N1 has killed more than 400 people, mainly in Southeast Asia, since first appearing in 2003. Another strain of bird flu, H7N9, has claimed more than 170 lives since emerging in 2013.

Defra said the type discovered at the duck farm is H5 - but not H5N1. The exact strain will be confirmed after final test results due today.

The NHS website states: "There are many types of bird flu, most of which are harmless to humans. However, two types have caused serious concern in recent years. These are the H5N1 and H7N9 viruses.

"Although these viruses don't infect people easily and are usually not transmitted from human to human, several people have been infected around the world, leading to a number of deaths.

"Other bird flu viruses (particularly H7N7 and H9N2) have also infected people, but these have rarely caused severe illness."

Public Health England is assisting Defra in the investigation of the outbreak at the farm in Yorkshire.

A spokesman said: "Based on what we know about this specific strain of avian influenza the risk to human health in this case is considered extremely low."

Meanwhile, Dutch officials on Sunday banned the transport of poultry in the Netherlands after the discovery of the H5N1 strain.

The "highly pathogenic" form of avian influenza discovered at a farm in the centre of the country is very dangerous to birds and "contamination can occur from animals to humans," the Dutch government said in a statement.

If it is a H5-virus but not H5N1 then there seems to be three choises; H5N6 was found in China this year, H5N8 is most likely or a new H5N? form. It is nice that "authorities" take measures but the virus that now proberbly did show up at three places in western Europe this month is spread by wild birds and proberbly widespread.

Absence of proof is not proof of absence.

The European Centre for Disease Control completed their risk assessment today, full assesment given in link. However here is what they say about human exposure based on its relationship with H5N1.

To date, no human infections with this virus ( H5N8 ) have ever been reported world-wide and the risk of zoonotic transmission to
the general public in the EU/EEA countries is considered to be extremely low. However, given the evolutionary history of
the virus with the HA gene evolved from the widely circulating H5N1 viruses, people in direct contact with/handling
diseased birds or poultry and their carcasses (e.g. farmers, veterinarians and labourers involved in the culling and
rendering) might be at risk of infection. Given this potential zoonotic risk, contingency plans for the control of avian
influenza in poultry and birds should be developed in collaboration with public health and occupational health authorities to
ensure that persons at risk are sufficiently protected from infection.

Appropriate personal protective equipment, including
respiratory protection, should be made available and used.
People exposed at the affected holdings should be monitored for ten days in order to document possible related symptoms.

Local health authorities may consider actively monitoring these groups and administering antiviral prophylaxis as
recommended for persons with exposure to A(H5N1) dependent on the local risk assessment (i.e. intensity of exposure).
Persons exposed as a result of their occupation should be offered vaccination against seasonal influenza, if they are not
already vaccinated.


They go on to question why they have simultaneously infections in Holland and UK in closed indoor holdings.


http://www.ecdc.europa.eu/en/Pages/home.aspx

Cases in brief.
On 6 November 2014, the German authorities reported an outbreak of highly pathogenic avian influenza (HPAI) virus
A(H5N8) at a holding with 31 000 fattening turkeys in the north-east of Germany.

On 16 November 2014, Dutch authorities reported an outbreak of HPAI virus due to A(H5N8) in a holding with 150 000
laying hens kept indoor located in Hekendorp (municipality Oudewater), north east of Rotterdam.

On 16 November 2014, UK authorities reported another outbreak of HPAI virus due to A(H5N8) in an indoor holding with
6 000 breeding ducks in North Yorkshire, England.

November 20 a second case in the Netherlands (although it still is H5N?). The problem is with the wild bird spreading it. Those birds do not realy get sick themselves. But of course dead wild birds can be eaten by cats, swine, etc. It might even end up in pigs sometime. The H5N8-vires may take the indirect road to humans via other mammals.

Why do you think is it getting into closed premises ? The ducks in UK were kept by a Chinese firm which breeds these ducks across Europe. They are kept in closed barns, workers entering have to wear protective overshoes etc so to stop contact with wild birds. The farms affected so far do seem to almost follow a straight line through Europe migration paths, so sure the wild birds are the vector. Maybe a bird can enter through a badly maintained building ?

Hazelpad, how the virus gets inside is also getting a big question in the Netherlands. Infected rainwater ? How long is the incubation-time ? In the Netherlands authorities are not rulling out the possibility of humans getting infected. The H5N8-virus is taken very serious. If humans (or other mammals) would get infected they might not even show clear signs, proberbly only (very) mild flusymptoms that can be ignored easy. And there is a danger, H5N8 could mix further and get more agressive.
