Bird Flu Cases Hit 35 Countries

The World Organization for Animal Health says the bird flu outbreak that is currently killing millions of birds in the United States has impacted 35 countries around the world.

The major strain in the U.S. that has led to the deaths of 33 million birds since last December is H5N2.  The USDA is now admitting that the H5N8 strain of bird flu has also been found in the United States.

The OIE says that the H5N8 strain was discovered in Korea and China before moving to Japan.

“From there the strain probably spread with migratory wild birds to India, Europe, Canada and later the United States of America,” the OIE said in a statement.

The OIE has requested that the 180 member countries apply better biosecurity measures at farms, live bird markets and in trades.  They’ve also requested an increase in surveillance to try and stop outbreaks before they can infect more than one location.

The OIE added that while the main focus is on H5N2 and H5N8, the H5N1 virus that lead to a worldwide outbreak in 2004 and also infected humans is still out there.  The virus has most recently been found in Africa.

Nebraska Declares State of Emergency Due To Bird Flu

Nebraska’s governor has declared a state of emergency because of a bird flu strain that has contributed to the termination of 33 million birds in 16 states.

Governor Pete Ricketts declared the state of emergency on Thursday after federal officials said a second farm in the state had tested positive for the avian flu virus.  The declaration is the fourth by governors after Wisconsin, Iowa and Minnesota.

The action by the governor would allow emergency funds to be release to the Nebraska Department of Agriculture and other state agencies tasked with stopping the spread of the flu virus.

Experts say the H5 strains post little threat to human health but are on the verge of record levels in the U.S.

“Having a second farm in Nebraska confirmed to have HPAI (highly pathogenic avian influenza) is unfortunate but not completely unexpected,” said Nebraska Department of Agriculture Director Greg Ibach.  “This follows the pattern we’ve seen in other states when it comes to the spread of the virus.”

Ibach said that 1.8 million birds will be destroyed.  The state’s first case resulted in the destruction of 1.7 million.

Iowa Bird Flu Cases Hit 25

Four new cases of bird flu have been found in Iowa including one farm with 2.8 million laying hens.  Three of the new cases are at commercial turkey farms in Buena Vista and Cherokee Counties.

The Iowa Department of Agriculture says that 19.4 million birds will be destroyed because of the virus, although that estimate did not include the number birds from the commercial turkey farms.

The farms will be quarantined and all the turkeys destroyed according to officials.  Every flock within 6.2 miles of the infected farms will be quarantined and tested to see if the virus has spread beyond the four new infected locations.

Governor Terry Branstad has declared a state of emergency so that state agencies can take strong measures to stop the virus from continuing to spread.  Cherokee, Clay, Kossuth, Madison, O’Brien, Osceola, Pocahontas, Sac and Sioux counties have all been impacted by the virus.

Scientists speculate that migratory birds such as ducks and geese have spread the virus through their droppings on the farms.  Farm workers then unknowingly spread the virus through dust or bird feathers.

The risk to humans is considered low according to health officials.

The outbreak is also causing concern among grocers because there is only seven months to Thanksgiving and it’s possible the farms will not be able to meet the demand for turkeys on the holiday.  The cost of turkey could skyrocket because of short supply.

Minnesota Declares State of Emergency Over Bird Flu

Minnesota has declared a state of emergency because of a strain of avian flu that has led to the elimination of 7.3 million birds.  It’s the second state to declare the emergency over the bird flu following Wisconsin.

The highly infectious strain of H5N2 bird flu has been found in 46 different Minnesota farms in 16 counties.  The disease has hit around 2.6 million birds.

State health officials are rushing doses of Tamiflu to farm workers or anyone else who has been in contact with the infected birds.  As of April 24th, no humans have been confirmed to have been infected with the H5N2 strain.

“There’s no reason for anybody in the state of Minnesota to be concerned about their own health,” Governor Mark Dayton said at a press conference on Thursday after declaring the state of emergency.

The H5N2 strain is so deadly to birds that an entirely infected flock will die within 48 hours.

Two bird flu strains have been discovered in the United States this year. The H5N2 strain is in Arkansas, Idaho, Iowa, Kansas, Minnesota, Missouri, Montana, North Dakota, Oregon, South Dakota, Washington and Wisconsin. It has also been identified on farms in Ontario, Canada.  The other strain, H5N8, was found in California and Idaho.

The top U.S. egg producing state, Iowa, reported the virus in a farm that has 3.8 million hens.

New Bird Flu Strain Has Pandemic Possibilities

Chinese scientists have taken the very rare step of making a public announcement concerning a new strain of bird flu.

The Chinese government usually tries to keep news about a new bird flu strain from being released into the public until it is a major health issue.  However, a new strain of the virus called H10N8 apparently has shaken health officials to the level they are acting quickly to warn the public.

A 73-year-old woman from Nanchang City in southeast China died after being the first person found with the virus and a second person is confirmed to be infected with the virus.  The scientists say the quick transmission makes it a more likely possibility the virus, which they believe transferred from wild birds to chickens, has mutated into a form that can be easily transmitted from birds to humans.

The report of the woman’s death published in the Lancet medical journal said “the pandemic potential of this novel virus should not be underestimated.”

Dr. John McCauley of the World Health Organization said that H10N8 does not cause serious disease in poultry and thus it is difficult to detect.  While they don’t believe the virus would transmit well between humans, Dr. McCauley admitted there was not enough information to make a definitive claim.

Bird Flu Claims Another Life In Hong Kong

The H7N9 bird flu has claimed another victim in Hong Kong.

The death marks the third death in the city since the arrival of the virus from China.  The male victim, who has recently visited the Chinese city of Shenzhen, was admitted to the hospital less than 24 hours before he died.

The World Health Organization has been quietly using a new term when talking about transmission of the virus between humans.  Studies of cases in China show that it is possible to transfer the virus between people so the term “sustained human-to-human transmission” is being used meaning that they don’t see infections happening on a mass scale.

The changes have happened since the virus was spotted in both Taiwan and Hong Kong, raising fears the virus is making its way out of China toward emerging nations that are not ready to handle the deadly virus.

The H7N9 virus was discovered last week at a Hong Kong market resulting in the slaughter of 20,000 birds.

H7N9 Mutation Resists Drugs

A mutation discovered in a new strain of bird flu has rendered the virus resistant to treatment drugs without limiting its ability to spread.

Most seasonal flu strains often become less transmissible when developing drug resistance, but scientists discovered that the H7N9 bird flu does not lose any of its spreading potential even with drug resistance.

Researchers said they do not believe this will make H7N9 any more likely to develop into a pandemic, but do recommend that doctors should be careful in their use of anti-viral medicines and consider using other drugs instead of Tamiflu to treat H7N9 cases.

The H7N9 bird flu has infected at least 139 people so far in China, Taiwan, and Hong Kong, and has killed 45 people.

New Bird Flu Strain Kills Chinese Woman

A strain of bird flu that was discovered in 1965 has infected a human being for the first time.

A 73-year-old Chinese woman died earlier this month of respiratory failure and a post-mortem examination showed she had contracted H10N8 bird flu.  The H10N8 strain was discovered in birds in 1965 but had never been found in a human being.

Doctors said the woman was admitted with severe pneumonia, high blood pressure, neuromuscular problems and a heart attack.  They had not suspected bird flu at the time of her admission.

Family members in contact with the woman have not shown symptoms of the virus. Officials say the woman had contact with animals at a live bird market four days before she fell ill.

Chinese health officials and the World Health Organization say they will be increasing their surveillance of hospitals to look for more potential H10N8 victims.

This is the second new bird flu virus to infect humans in China in 2013.  H7N9, which has killed 45 of the 137 people it has infected, was discovered in March 2013.

Scientists Discover Disturbing Fact Regarding H7N9 Bird Flu

It had been a long established scientific fact that when a flu virus obtained an immunity to particular anti-viral flu medications, they would become less effective in transmission between humans.

Now scientists have found the deadly H7N9 bird flu in China does not lose any of its infectivity when it becomes resistant to commonly used drugs like Tamiflu.

The researchers were quick to add that the drug-resistant H7N9 was not more infectious than in the past. They reiterated that the virus is one of the less transmittable viruses between humans.

H7N9 emerged earlier this year in China and has killed 45 of the 139 people confirmed to have been infected with the virus. Scientists had initially believed H7N9 could not transmit between humans but found cases in August of human-to-human transmission.

A separate study in the United States this week said that it was not impossible for H7N9 to mutate into a form that could be easily passed among humans.

Hong Kong Confirms First Bird Flu Case

Health officials in Hong Kong have announced confirmation of the country’s first case of H7N9 bird flu.

The announcement is a sign that the deadly virus is spreading beyond the borders of mainland China.

The announcement of the confirmed case comes on the 10th anniversary of the outbreak of SARS (Severe Acute Respiratory Syndrome) that killed 300 people in Hong Kong and seriously damaged the country’s travel and retail industry.

The 36-year-old H7N9 victim reportedly traveled to Shenzhen in mainland China and had contact with poultry during his visit. Officials say the patient is in critical condition in a Hong Kong hospital.
