CHANGSHA – 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. Continue reading

Nature – Preventing seasonal sniffles may be more complicated than researchers suspected. A vaccine that protects piglets from one common influenza virus also makes them more vulnerable to a rarer flu strain, researchers report today in Science Translational Medicine1.
The team gave piglets a vaccine against H1N2 influenza. The animals responded by making antibodies that blocked that virus — but aided infection with the strain H1N1, which caused a pandemic among humans in 2009. In the study, H1N1 infected more cells and caused more severe pneumonia in vaccinated piglets than unvaccinated ones.
The root of the different immune responses lies with the mushroom-shaped haemagglutinin protein found on the outside of influenza-virus particles, which helps them to attach onto cells in the airways. The protein occurs in all types of flu, but the make-up of its cap and stem vary between strains….>Continue Reading<<

CHINA – 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”.

By 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.” Continue reading
The Poultry Site – At the same time, the Chinese poultry sector is still having trouble and continues to recover from the crisis caused by avian influenza. The Chinese government just announced that it is giving the industry 300 million yuan (48.5 million dollars) more to help the poultry industry in its recovery. This is added to the 900 million yuan that has already been given to the industry. Aside from the central government subsidies, ten provinces have established preferential policies to support the poultry industry.

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<<
The Poultry Site – The duck genome consortium, consisted of scientists from China Agricultural University, BGI, University of Edinburgh and other institutes has completed the genome sequencing and analysis of the duck (Anas platyrhynchos), one principal natural host of influenza A viruses, which caused a new epidemic in China since this February.
This work reveals some noteworthy conclusions and provides an invaluable resource for unraveling the interactive mechanisms between the host and influenza viruses.

ANALYSIS – At its global meeting this week, OIE has agreed new standards on tackling antimicrobial resistance and on broiler welfare. Research to develop a vaccine against necrotic enteritis has taken a step forward and an agreement has been signed between a French-based animal health company and a Chinese university for the development of a new H5N1 influenza vaccine.
ANALYSIS – A new study from the US shows just how poor storage conditions can be at retailers and on farms for animal health products. If the results represent the industry generally, it is little wonder that vaccines, antibiotics and other products sometimes give disappointing results! There are signs that the H7N9 avian flu crisis is abating in China and the Mexican authorities have reported no new outbreaks in the region of Puebla. However, another low-pathogenic form of the flu virus has been reported at a farm in Spain in the last week.
Animal health products including vaccines and antibiotics usually have defined storage conditions to maintain their efficacy. These conditions, stated on the packaging, need to be kept to throughout the supply chain but a recently published case study involving beef producers in Idaho has revealed less-than-ideal refrigeration storage conditions for these products at retailers and on-farm.
Idaho beef producers and animal health product retailers participated in a study to gather data on the handling and management of animal health products.
In the study, the University of Idaho placed data loggers in 176 refrigerators (129 belonging to producers and 47 with retailers), recording temperatures in 10-minute intervals for a minimum of 48 hours.
The approximate age, type and location of the producers’ refrigerators were recorded, along with where the products were stored in the refrigerator. An inventory of each producers’ refrigerator was taken, with expired and opened products recorded.
Almost one-third (31 per cent) of the producers’ refrigerators maintained the recommended temperature range of 2 to 7°C for more than 95 per cent of the time but one-third (33 per cent) of the producers’ refrigerators maintained the recommended temperature range less than five per cent of the time.
Thirty-four per cent of the retailers’ refrigerators were within the recommended temperature range for more than 95 per cent of the time. However, 17 per cent were in the range less than five per cent of the time. More than 40 per cent of retailers did not monitor refrigerator temperatures.
Turning to news of bird flu, no new human cases of avian influenza A(H7N9) have been reported in China in the last week and official are doing their utmost to convince the local population that the danger is over, including eating poultry meat in public. H7N9-positive samples are still being reported at some markets.
Shanghai retailers are now allowed to sell chicken meat again, which will come as a relief to hard-pressed poultry farmers who have seen close to a market collapse for their product over the last few weeks.
Low-pathogenic H7N1 avian flu has been reported in breeding hens at a farm in the Spanish region of Catalonia in the last week. Of the 12,000-plus birds in the flock, 133 died and rest have been destroyed.
In Mexico, surveillance has uncovered no new cases of bird flu in Puebla, according to the Ministry of Agriculture (SAGARPA).
