10 seals wash up dead, HUNDREDS dead in past two months in Denmark and Netherlands

Dead Seals in Germany

Seal sanctuary Pieterburen and scientists from Erasmus University have confirmed that seal flu is now also in the Netherlands.

In September and October 10 to 15 percent of the seal population in Germany and Denmark died because of this flu. The expectation is that the H10N7 virus will cause as much damage to the seal population in the Netherlands.

In the past week 10 dead seals washed up in the Dutch Wadden area. A veterinarian from Pieterburen took monsters and scientists at the Erasmus University subsequently confirmed that all these animals were suffering from H10N7 virus.

The H10N7 virus is an influenza virus that originates from birds. The virus is not dangerous to birds, but is very dangerous for seals. There is no connection between this virus and the current outbreak of bird flu in chickens in Hekendorp.

The virus is most probably not dangerous to humans, says virologist Ab Osterhaus. “We are working on a vaccine, but we first have to get permission to vaccinate the seals.”

31,000 birds killed to outbreak of Avian flu in Mecklenburg-Vorpommern, Germany

H5N8 Virus Alert

A highly contagious flu virus added to poultry farmers in trouble. 31,000 turkeys are killed in Pomerania. The virus was previously known only in Asia. As the disease came to Germany, is unclear.

Heinrichswalde / Schwerin first time, a previously known only from Asia and dangerous avian pathogens in Germany has emerged. The affected turkey operation with about 31,000 animals in the Vorpommern-Greifswald was locked. The turkeys are infected with the influenza virus subtype H5N8. On Thursday began with the killing, which is expected to close on Friday.

Mecklenburg-Vorpommern Ministers of Agriculture Till Backhaus (SPD) said, on the evening cautious confidence that the disease remains limited to operation in Heinrichswalde. In contrast to the first major outbreak of bird flu in February 2006, had previously been discovered in Mecklenburg-Vorpommern not infected wild bird.

In the turkey fattening farm there was increased death rates since the beginning of the month, which would have increased in the past few days, the President of the Friedrich-Loeffler Institute (FLI), Thomas Mettenleiter dpa said. The FLI is the Federal Research Institute for Animal Health.

As the causative agent of avian influenza or bird flu came into the stock, is therefore unclear. The FLI have four experts sent to the site, the search for the causes. Finally, a highly contagious pathogen H5 in 2008 occurred in Germany.

“We have to assume that every highly pathogenic virus can also be a hazard to humans,” Mettenleiter said. For the H5N8 pathogen transmission to humans is not yet been observed – not even in South Korea, where hundreds of thousands of animals had been killed. But experts see no reason to panic.

Backhaus warned, however, it must be crucial to ensure that the virus does not jump to mammals. Within a radius of 50 kilometers around the outbreak of the bird immediately must remain in the stable. Even pet owners in the vicinity of water resting places of migratory birds on lakes and along the Baltic coast to bring their chickens, ducks and geese in the barn.

In the words of the county official veterinarian Holger bird in Anklam the area where animals have in the stable enough over the circle Vorpommern-Greifswald addition to the Uckermark (Brandenburg), the Mecklenburg Lake District and Poland.

Avian flu virus found among penguins in Antarctica

alert-now.gif

An international team of researchers have for the first time identified a new avian influenza virus in a group of Adelie penguins from Antarctica. 
 
The virus is unlike any other circulating avian flu viruses. 
 
While other research groups have taken blood samples from penguins before and detected influenza antibodies, no one had detected actual live influenza virus in penguins or other birds in Antarctica previously, said senior research scientist Aeron Hurt at the WHO Collaborating Centre for Reference and Research on Influenza in Melbourne, Australia. 
 
The virus did not cause illness in the penguins but the study shows that avian influenza viruses can get down to Antarctica and be maintained in penguin populations, he said. “It raises a lot of unanswered questions,” Hurt added. They include how often Avian Influenza Virus (AIVs) are being introduced into Antarctica, whether it is possible for highly pathogenic AIVs to be transferred there, what animals or ecosystems are maintaining the virus and whether the viruses are being cryo-preserved during the winters. 
 
For the study, Hurt collected swabs from the windpipes and posterior openings of 301 Adelie penguins and blood from 270 penguins from two locations on the Antarctic Peninsula: Admiralty Bay and Rada Covadonga. The samples were collected during January and February 2013. 
 
Using a laboratory technique called real-time reverse transcription-PCR, the researchers found AIV genetic material in eight (2.7%) samples, six from adult penguins and two from chicks. Seven of the samples were from Rada Covadonga. The researchers were able to culture four of these viruses demonstrating that live infectious virus was present.

Deadly Flu Virus Set To Spread Like Wildfire In Ireland Warns Expert
 
Flu Alert

A deadly flu outbreak that has already claimed five lives is set to spread in Irish hospitals.

One expert has warned that overcrowding in emergency rooms will see the influenza virus ‘spread like wildfire.’

The Irish Independent reports that Dr Fergal Hickey, President of the Irish Association of Emergency Medicine, blamed the overcrowded emergency departments for the exacerbated seasonal spread of flu.

Dr Hickey has predicted that the worsening flu outbreak could spread quickly and lead to more deaths amid growing concerns about the spread of influenza and its potential to trigger more fatalities.

The paper reports that the number of reported deaths has risen sharply in the past week after a spike in people contracting the virus.

Already five influenza-associated deaths, including an infant under four, have been recorded.

Dublin’s Beaumont Hospital imposed visitor restrictions over the weekend as it fought a flu outbreak.
Overcrowding at hospitals is seen as the biggest factor behind the rise in cases of flu.

The report says that in the first week of February, the rate of people presenting to their doctor with influenza-like illnesses in Ireland increased to 32.4 per 100,000 population, from a rate of 20.5 per 100,000 the week before.

Mexican Gov’t Reports 421 Flu Deaths In 2014

H1N1 Flu Alert

A total of 421 people died from influenza between Jan. 1 and Feb. 7 in Mexico, the Health Secretariat said.

Of the total deaths registered during the period, 390 were from the AH1N1 strain, two from the AH3N2 virus, one from type B influenza and the remaining 28 deaths from other strains of the virus.

Laboratory tests have confirmed 3,679 influenza cases since Jan. 1, of which 3,114 were of the AH1N1 strain, 193 of the AH3N2 type, 57 of the type B influenza virus and 315 of other strains, the secretariat said.

Two deaths were registered between Jan. 31 and Feb. 7, compared with 23 the previous week and 156 between Jan. 5 and Jan. 11, the deadliest week of the 2014 flu season, the secretariat said.

The infection and death figures will be adjusted as laboratory results are received, the Health Secretariat said.

Adults between the ages of 35 and 55 who suffer from chronic diseases, such as obesity and diabetes, are hardest hit by the seasonal flu outbreak, health officials said.

The AH1N1 flu virus responsible for the 2009 pandemic is now a seasonal virus, the secretariat said.

The AH1N1 influenza strain was detected in Mexico between March and April 2009.

Around 1,300 people died and more than 70,000 were infected by AH1N1 in Mexico, where a health alert was kept in place until June 29, 2010.

4000 Chickens Died And 125,000 Slaughtered Due To Outbreak Of Avian Flu In Hebei, China

Bird flu alarm in China: The H5N2 virus is reportedly erupted in the northeast of the People’s Republic. Since early last week, the virus called thousands of dead chickens

Chinese authorities have reported the outbreak of the avian influenza virus H5N2 in the north east of the country. On a poultry farm in Baoding in Hebei Province, more than 125 000 chickens were slaughtered, the State agency Xinhua reported on Sunday. Around the farm had to be closed and disinfected a three square kilometer area. 4,000 chickens were found dead there since Tuesday.

Another Avian Flu (H6N1) Jumps To Humans

Domestic chickens.

It’s becoming obvious to health news followers in the 21st century that avian flu like influenza A (H7N9), discovered in March, only endanger humans if the parent bird disease mutates. This has occurred again in 2013 with the H6N1 strain, the online journal Lancet Respiratory Medicine reported on Thursday.

Sung-Hsi Wei of the School of Medicine at National Yang-Ming University and Centres for Disease Control, Taipei, Taiwan, reported the case with four main colleagues and others. They found lower respiratory tract illness associated with avian H6N1 influenza virus, never previously discovered in people. The patient was a 20-year-old woman from Taiwan who was short of breath and hospitalized in May with a lung infection. After treatment with Tamiflu and antibiotics, she was able to return home.

Experts at the Taiwan Centres for Disease Control used virus isolation and sequencing to identify her infection as H6N1 bird flu, originating in the wild but widely appearing in chickens. The patient had worked in a deli. Although she had no known connection to live birds, investigators noted several people close to her also developed flu-like symptoms but did not test positive for H6N1.

In an accompanying article, “The expanding list of zoonotic influenza viruses,” Marion Koopmans, a Dutch virologist, applauded the work and offered a rhetorical comment: “The question again is what would it take for these viruses to evolve into a pandemic strain?”
Dr. Koopmans said it was worrying that scientists had no early warning signals that bird flu could be a problem until humans got ill, Maria Cheng reported for AP.

“Scientists often monitor birds to see which viruses are killing them, in an attempt to guess which flu strains might be troublesome for humans—but neither H6N1 nor H7N9 make[s] birds very sick.”

180,000 Salmon Killed Due To Outbreak Of Disease In Gulen, Norway
Infectious salmon anemia (ISA) is caused by a virus that is probably of the same family as the influenza virus and spreads quickly.

It was Firda Sjøfarmer AS and fish health as forecasts on suspicion of ISA on his fish in a plant in Vatnøy in Gulen earlier this week, write Firda. After the discovery of abnormally many dead fish and symptom of the disease took FSA samples and confirmed the ISA virus infection.

Breeders slaughtered all the fish in one day, well jumper 180,000 with an average weight of about 250 grams.
