H7N9 kills 2 more, causing new infections in China

39CHANGSHA – A 59-year-old man having close contact with live poultry died on Monday morning of the H7N9 flu virus, the first of its kind in central China’s Hunan province, local authority said.
A separate statement issued by the health department of Guangdong province on Monday said a patient surnamed Xie died of the virus on Sunday in Foshan after treatment failed.
With the new cases, H7N9 has so far killed 25 people in China since January, and the number of human infections has been 113, with Zhejiang and Guangdong being mostly affected.

Tense Vigil in China as Nasty Flu Virus Stirs Back to Life

31

By Christina Larson

Science – As flu season bears down, the world is warily eyeing China. A novel H7N9 avian flu strain emerged here in March, infecting at least 135 people and killing 45 before petering out in the summer. Now it is back, with four human cases in southern China in the past month. More cases are a certainty, and researchers, public health experts, and vaccinemakers are preparing for the remote but real possibility that H7N9 will explode into a pandemic.

For now, the signs are reassuring. Sustained human-to-human transmission would be needed for H7N9 to cause widespread illness. But so far, there have been only a handful of possible instances of people infecting each other. In 70% of cases, victims are believed to have picked up the virus directly from live poultry, says Masato Tashiro, head of a World Health Organization (WHO) flu collaborating center in Tokyo. H7N9 is “still looking for ways to adapt well to humans,” says George Gao, deputy director-general of the Chinese Center for Disease Control and Prevention (China CDC).

Bird Flu, Slowdown Hit Sales at Fast-food Chains

39CHINA – The bird flu scare and the economic slowdown hit the sales of some Western fast-food chains in China last month.
 
Yum! Brands Inc’s same-store sales in China declined an estimated 13 per cent year-on-year in July, with a 16 per cent decrease at KFC and only three per cent growth at Pizza Hut, Yum! Brands said on Monday (12 August).
 
Meanwhile, McDonald’s Corp — Yum! Brands’ main rival — also saw a sales decrease in China.
 
The company said on 8 August that comparable sales in Asia-Pacific, the Middle East and Africa decreased 1.9 per cent in July, “reflecting negative results in Japan, Australia and China”. Continue reading

Bird flu appears to have spread from human to human

1By Kate Kelland
MSN News — Research published in the British Medical Journal analyzing a family cluster of cases of the bird flu infection H7N9 in eastern China found it was very likely the virus “transmitted directly from the index patient (a 60-year-old man) to his daughter.”
 
Experts commenting on the research said while it did not necessarily mean H7N9 are any closer to becoming the next flu pandemic, “it does provide a timely reminder of the need to remain extremely vigilant.”

Bird flu may come back stronger when seasons change

27By Kate Kelland
MSN News – A new and deadly strain of bird flu that emerged in China in February but seems to have petered out in recent months could reappear later this year when the warm season comes to an end –and could spread internationally, scientists said on Monday.

A study by researchers in China and Hong Kong found only one human case of the H7N9 bird flu strain has been identified since early May.

In the preceding months, the virus, which was unknown in humans until February, has infected more than 130 people in China and Taiwan, killing 37 of them, according to the World Health Organization (WHO).

“The warm season has now begun in China, and only one new laboratory-confirmed case of H7N9 in human beings has been identified since May 8, 2013,” the researchers wrote in a study published in The Lancet medical journal.

But they added: “If H7N9 follows a similar pattern to H5N1, the epidemic could reappear in the autumn.” >>Continue Reading<<

Counting the Cost – of Poultry to the Environment and Avian Flu to the Industry

49By Jackie Linden
The Poultry Site – A University of Delaware study has found poultry manure to be less environment-polluting than previous thought. A new report, however, highlights the contribution of livestock to greenhouse gas emissions, while researchers have identified changes in manure management and nutrition that could greatly mitigate the impact from poultry. China is beginning to count the cost of the H7N9 flu outbreaks to its poultry industry.
A new study in the US has found that poultry production brings a lower environmental burden than thought.
Federal environmental programmes have drastically overestimated poultry industry contributions to water pollution, according to a University of Delaware-led study that could trigger changes to river and bay clean-up plans across Delmarva and around the country.
James L. Glancey, a professor in the university’s Bioresources Engineering and Mechanical Engineering departments, said that a multi-state study, based on thousands of manure tests, found that actual nitrogen levels in poultry house manure are 55 per cent lower than the Environmental Protection Agency’s decades-old, lab-based standards.
This work could significantly impact the future of poultry farming in the Chesapeake Bay area, where a forecasting model has been used to guide a federally backed attempt to restore the bay’s health and ecosystems and assign clean-up goals.
Growth in agricultural production has resulted in increased agricultural greenhouse gas (GHG) emissions – with a huge proportion of emissions coming from livestock production, according to a new report from the Worldwatch Institute.
In Japan, researchers comparing the figures for the output of GHG for pig and poultry production in France and Japan found that changing the manure handling process and increasing the use of synthetic amino acids in feeds could be beneficial in reducing GHG output.
Avian influenza can be very costly for the poultry industry, as the Chinese are finding to their cost. Official figures released this week by the China Animal Agriculture Association estimated that since the H7N9 influenza outbreak the poultry industry has recorded losses of more than 40 billion Yuan (US$6.5 billion).
The central government announced this week subsidies of 600 million Yuan ($96.77 million) to support the poultry producers across the country as live bird markets were closed to control the disease and poultry meat demand slumped. Processing companies will receive short-term subsidized loans and local financial institutions are being encouraged to offer credit aid to breeders and companies.
The China Development Bank, the country’s policy lender has said it has issued emergency loans worth 116 million Yuan (US$18.7 million) to help poultry firms cope with the impact of avian flu.
Chinese economists are predicting fewer cases of H7N9 flu in May and a dramatic improvement in market fortunes by mid-summer.
On human cases of influenza A(H7N9), the latest report from China gives the tally as 130 confirmed cases and 35 deaths from the virus.
Global players are also seeing bird flu affect their bottom lines. McDonald’s Corporation, for example, reported comparable sales in April 2.9 per cent below the same month last year in Asia/Pacific, Middle East and Africa, which the company attributed to the impact of bird flu, especially in China.
Bird flu outbreaks have also been reported this week in Nepal (in a backyard flock; virus subtype unknown), in North Korea (H5N1 highly pathogenic virus in domestic ducks) and Tibet (H5N1 in a mixed flock of village poultry).

H5N1 Researchers Announce End of Research Moratorium

Flu1By David Malakoff
Science – Almost a year after they announced it, leading influenza researchers are ending a voluntary moratorium on certain types of controversial experiments involving the H5N1 avian influenza virus.

In a letter published online today by Science and Nature, 40 researchers declare that the studies should restart now that scientists, government officials, and the public have had time to debate the need for the research and impose new safety measures. “[T]he aims of the voluntary moratorium have been met in some countries and are close to being met in others,” they write, and researchers “have a public-health responsibility to resume this important work.”
