That's a great image, Al!

We should have been more specific in our introduction of the idea on this thread.

A great deal of backing data is found on the standard GeneWurx RnR Analytic Summary entitled Cross Serotype Homology covering the first and second human sequence deposits at GISAID. Although the graphic does illustrate, in general, what we believe is a valid permutable set, our comments on this thread were intended to be much more specific toward a proposed mechanism driving the development of the emergent H7N9 Hemagglutinin via accumulative sub-segment genetic transfer from a number of different serotypes in two separate classes of influenza over a time duration of at least 4 years and potentially 11 years.

Let's bring the diagram title into that discussion when you have a moment.

I am not a genetics expert but it seems to me that if H7N9 is an avian influenza that is fairly well adapted to mammals (as proven by sequence analysis), it must have cycled through swine. Swine are mammals and could be responsible for the mammalian adaptation - which indicates to me that this flu is widespread on pig farms.

The MOA mentioned this possibility in their paper published online yesterday:

"Thirdly, beyond that the virus can infect humans and birds, we think that the virus can also infect pigs which support circulation of both AIVs and human influenza viruses."

the mammalean adaption had been exaggerated.
It's just those 2 "mammalean" mutations.
We had seen them before in birds.
It was just surprising to see them just after
the Fouchier-Kawaoka predictions.

The virus is still avian since decades.

Ministry of Agriculture: avian influenza prevention and control practices worthy of promotion
May 2, 2013 09:12:49 Hangzhou Network Views: 64
Ministry of Agriculture, the World Organization for Animal Health (038) consisting of animal H7N9 avian influenza prevention and control of the joint mission arrived in the city, a two-day inspection in Shanghai. On the morning of April 26, Shanghai Municipal Agricultural Commission briefed the Expedition animal H7N9 avian flu prevention and control work, monitoring and sampling, laboratory testing and market traceability topic for the exchange and discussion. In the afternoon of April 26, the study group also inspected the wholesale market Sanguantang eggs, City animal disease prevention and control center laboratory.
.....Designated road crossing inspection and non-designated crossing inspections and found no live poultry transport vehicles.
April 26, the city animal disease prevention and control center 560 samples were collected, and samples of avian influenza virus nucleic acid detection, results were negative.

From another thread - prevention info-
Good indoor and outdoor sanitation, garbage removal, elimination of flies, mosquitoes, rats, cockroaches likely to spread disease vectors. Disinfection and hygiene of the pet home, when they go out as much as possible to reduce livestock unnecessary contact.

　　Information Office of the Ministry of Agriculture released on May 5, the National Avian Influenza Reference Laboratory report detected in environmental samples were positive for the H7N9 avian influenza in Shandong collected 412 samples from Zaozhuang City, Shandong Province, Xingfu Road market. Suspected positive samples Jiangxi animal disease prevention and control center for inspection by the National Avian Influenza Reference Laboratory review, were positive for H7N9 avian influenza, chicken samples from a business point of Nanchang, Jiangxi Province, Nanchang County to the Town. Guangdong provincial animal disease prevention and control center for inspection of a suspected positive samples for review by the National Avian Influenza Reference Laboratory were positive for the H7N9 avian influenza, chicken samples from Dongcheng, Dongguan City, Guangdong Province, three birds wholesale market. Gene sequence analysis showed that all isolates of the H7N9 avian influenza virus strains isolated from pigeons and April 4 highly homologous.

　　Ministry of Agriculture has asked the Shandong Province, Jiangxi Province, Guangdong Province, in strict accordance with the Ministry of Agriculture, Animal H7N9 avian influenza emergency response guide (Trial) "do a good job related to disposal.

Experts reported that live poultry farms H7N9 is likely to be the source of infection

On May 19, 2013 09:59Source: World Wide Web

Released Monday by the Xinhua News Agency, Beijing, May 18 - National Health and Family Planning Commission of China - World Health Organization of human infection with the H7N9 avian influenza prevention and control of joint study group to examine the report pointed out that the live poultry farms is likely to be H7N9 infection source.
　　
By the invitation of the Chinese Ministry of Health and Family Planning Commission, the World Health Organization convened influenza epidemiology, virology, clinical and international experts in the field of Chinese experts together to form a joint study group recently to inspect the Chinese people infected with the H7N9 avian flu situation assessment and completed this inspection report.
　　
The report found around the live bird markets in Shanghai H7N9 bird flu H7N9 virus, a large number of cases have a history of exposure to live or live poultry market, close the live bird markets descendants of infection the number of cases decreased significantly. These tips, live poultry exposure of human infection with the H7N9 avian influenza virus of the key risk factors.
　　
Although the live poultry farms have not found the virus, but they are likely to be the source of infection where the virus is then in the live poultry market continues to expand, leading to human infection. Although still under investigation early stages of limited data, but it appears that due to the inter and intra provincial trade of live poultry, the H7N9 avian influenza virus will continue to exist. The poultry infection can not be controlled, the virus may spread to other provinces in China, leading to the threat of zoonotic increase, thereby enhancing the outbreak evolved into the possibility of an influenza pandemic.
　　
The report, to date, virology is still very limited, but found by gene sequencing of human infection with the virus and virus infection in poultry, this H7N9 avian influenza virus has been adjusted or have the ability to infect humans .

Animal H7N9 avian influenza surveillance sampling and laboratory testing has been completed

At 8:57 on May 24, 2013 Source: Economic Times　participate in interactive ( 0 ) 0

Human infection with H7N9 avian influenza occurred since the veterinary departments at all levels actively carried out in accordance with the request of the Ministry of Agriculture monitoring, current monitoring sampling and laboratory testing work has been basically completed.

As of May 22, the national veterinary laboratories were detected at all levels to complete 899,758 samples, covering 31 provinces and the Xinjiang Production and Construction Corps 42,250 monitoring sampling field point. No country was isolated from poultry farms H7N9 avian influenza virus, also found no pigs infected with the virus.

Expert analysis, monitoring results from the current look, from the country more than 30,000 samples of poultry farms all test results were negative and 53 positive samples, 51 were from the live poultry business field point, accounting for 96%. Experts believe that the live animal markets and poultry virus infection is a major source of risk, the current focus on prevention and control of poultry farms is still protected to prevent contamination by the virus.
