BEIJING (AP) - Nearly 90,000 pigs have died or been slaughtered because of blue ear disease, a Ministry of Agriculture official said Wednesday, part of the cause of a spike in pork prices.
The epidemic has now spread to 25 provinces or regions, said Li Jinxiang, a veterinarian with the ministry. China has 23 provinces, five autonomous regions and four self-governed municipalities.
Li told a news conference that by the start of this week, 165,144 pigs had contracted the disease. So 45,546 had died and another 42,728 had been slaughtered.
Li said the ministry had developed a vaccine for the epidemic and would start delivering it next month.
Last week, the ministry said [COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif][COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif]wholesale [/FONT][COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif]prices[/FONT][/COLOR][/FONT][/COLOR][/COLOR] for pork had jumped nearly 75 percent in the last year. Prices are expected to remain high, fueling fears of higher inflation, which rose to 3.4 percent in May, the highest in two years.
China's leaders have expressed concern about the prices. In May, Premier Wen Jiabao ordered local governments to increase food assistance for low-income families and to offer farmers subsidies to encourage pig-rearing.
Many farmers have stopped raising pigs for fear they might be stricken by the disease, authorities say.

The disease, also called porcine reproductive and respiratory syndrome, was first identified in the United States in 1987, according to the Web site of the World Organization for [COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif][COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif]Animal [/FONT][COLOR=#0000cc! important][FONT=Arial, Helvetica, sans-serif]Health[/FONT][/COLOR][/FONT][/COLOR][/COLOR].

Blue-ear pig disease affected 22 634 pigs in 32 counties in 11
Chinese provinces between 1 and 22 Jul 2007, killing 6433 and
requiring the culling of 15 728, an official with the Chinese
Ministry of Agriculture (MOA) said on Wednesday [25 Jul 2007].

The official told a news briefing that the number of cases had
declined from the previous month but did not provide any figures to

The MOA said that from 1 Jan to 22 Jul 2007, 165 144 pigs in 25
provinces were infected with the disease, of which 45 546 died and 42
728 were culled.

Li Jinxiang, an inspector with the Veterinary Bureau under the MOA,
said, compared with last month [June 2006], the numbers of
disease-hit counties, dead pigs and culled pigs were all declining
thanks to increased supplies of vaccines and financial aid from the MOA.

According to Li, about 150 million milliliters of the vaccine have
been used to curb the spread of the pig disease by 25 Jul 2007.
Another 250 million milliliters would be produced in August 2007. The
MOA has already allocated 10.8 million yuan [USD 1.43 million] to
finance affected areas.

On the current tight market supply of pigs and the price hike of
pork, Li said the supply was expected to increase early next year
[2008] and the pork price would remain at a relatively high level in
the near future

[The original Chinese text of the above (somewhat abridged) newswire
is available at
<http://news.sina.com.cn/c/2007-07-25/162113525996.shtml>.

The number of affected provinces (25) means that almost the entire
territory of China has been affected by highly pathogenic PRRS ("blue
ear disease"); China administers 22 provinces out of a total of 33
province level divisions. This underlines the potential of the
disease as a transboundary, highly infectious disease with potential
international impact.

China is known to be the world's leading pork producer, maintaining
about half of the world's pig population, which exceeds one billion
pigs. The mortality of 45 546 pigs out of a population of at least
500 million (and there are higher estimates) seems rather negligible
(less than 0.1 percent). If it is indeed a disease which causes the
reported decline in pig numbers to the extent of souring pork prices,
its morbidity and mortality figures are in need of verification.

An official OIE update will be helpful. - Mod.AS]

It said recent soaring pork prices in China are the result of blue ear disease, which has so far killed 25 pct of the country's pig population.

That seems more in keeping with this article... A few excerpts...

Here, we describe for the first time an unprecedented outbreak of highly pathogenic PRRS in China in 2006, which spread to more than 10 provinces (autonomous cities or regions) and infected over 2,000,000 pigs, resulting in about 400,000 fatal cases.

All work on autopsy samples as well as the following immunohistochemistry experiments were conducted by the China Animal Disease Control Center (CADC) in a bio-safety level 3 (BSL-3) facility.

Virus Spreading Alarm and Pig Disease in China

Liu Minghong, a farmer in Sichuan Province, said he lost 70 pigs to a virulent disease, leaving him with

By DAVID BARBOZA
Published: August 16, 2007
CHENGDU, China, Aug. 9 ? A highly infectious swine virus is sweeping China's pig population, driving up pork prices and creating fears of a global pandemic among domesticated pigs.

In Gu Yi, a village in Sichuan Province, a veterinarian's banner claims he can cure blue-ear disease, but the virus still spreads.

Animal virus experts say Chinese authorities are playing down the gravity and spread of the disease.

So far, the mysterious virus ? believed to cause an unusually deadly form of an infection known as blue-ear pig disease ? has spread to 25 of this country's 33 provinces and regions, prompting a pork shortage and the strongest inflation in China in a decade.

More than that, China's past lack of transparency ? particularly over what became the SARS epidemic ? has created global concern.

"They haven't really explained what this virus is," says Federico A. Zuckermann, a professor of immunology at the University of Illinois College of Veterinary Medicine. "This is like SARS. They haven't sent samples to any international body. This is really irresponsible of China. This thing could get out and affect everyone."

There are no clear indications that blue-ear disease ? if that is what this disease is ? poses a threat to human health.

Though the Chinese government acknowledges that the current virus has devastated pig stocks in coastal and southern areas, it has not admitted what experts say is clear: the virus is rapidly moving inland and westward, to areas such as this one in Sichuan Province, China's largest pork-producing region.

"This disease is like a wind that swept in and passed from village to village," said Ding Shurong, a 45-year-old farmer in a village near here who lost two-thirds of his pigs . "I've never seen anything like it. No family was left untouched."

No one knows for sure how many of this country's 500 million pigs have been infected. The government says officially that about 165,000 pigs have contracted the virus this year. But in a country that, on average, loses 25 million pigs a year to disease, few believe the figures. In part, the skepticism comes from the fact that pork prices have skyrocketed 85 percent in the last year ? an increase that, absent other factors, suggests the losses from disease are more widespread than Beijing admits.

And there are other signs. Field experts are reporting widespread disease outbreaks. Fear among pig farmers that their livestock will contract the disease has led to panic selling. And the government and media here have issued alarming reports that farmers are selling diseased or infected pigs to illegal slaughterhouses, which could pose food safety problems.

International health experts are already calling this one of the worst disease outbreaks ever to hit Asia's livestock industry, and they fear the fast-mutating pathogens could spread to neighboring countries, igniting a worldwide epidemic that could affect pork supplies everywhere.

A similar virus has already been detected in neighboring Vietnam and Myanmar, and health experts are trying to determine if it came from China.

Health experts say China has declined to send tissue samples to testing labs outside the country for independent verification by a lab affiliated with the World Organization for Animal Health in Paris.

The Chinese government says that it has reported the disease to international health bodies and insists that the disease is under control and that a vaccine has been developed and distributed.

But, some scientists say there is no truly effective vaccine against blue-ear pig disease (which is also known as porcine reproductive and respiratory syndrome); other experts say they are not even certain that the blue-ear virus is the one that is spreading.

Scientists who track blue-ear pig disease are puzzled because the disease is generally not so deadly.

"This virus generally makes them ill but on its own it doesn't cause a lot of deaths," said Steven McOrist, a professor of pig medicines at the University of Nottingham in England. "The evidence they put up so far is not conclusive."

If it is blue-ear pig disease, which has infected most parts of the world, including the United States, it may be a new and more virulent strain.

"This is more severe than we've seen elsewhere," said Derek Armstrong, a senior veterinary scientist at the Meat and Livestock Commission in Britain. "It may be a co-infection of pigs with other things."

The United Nations Food and Agriculture Organization is now pressing China to share its research and tissue samples.

"I've asked my two vets in Beijing to work with the government and get some of those samples out," said Juan Lubroth, head of infectious disease at the F.A.O., noting that China has reported its own findings on the disease. "Our experience has shown us that working with carrots is better than working with sticks."

Blue-ear pig disease has devastated the Chinese swine stock, leaving farmers like Xiong Yuqun, above, with a bleak outlook.


Government scientists themselves said that last year the virus affected two millions pigs and killed 400,000. Here in Sichuan province, home to some 55 million pigs and one of the world's most densely populated pig breeding areas, there is devastation. Many pig farmers say that what appears to be the blue-ear virus swept through this region in June and July, killing thousands of pigs.

"First they refused to eat, then they got high fever," said Zhao Yanjun, 32, who lost all but 5 of his 150 pigs, just months after building a modern barn in Heishi village, about an hour's drive southwest of Chengdu. "Now, there's nothing left."

Liu Minghong, a 38-year-old farmer, said, "Most of my pigs got hit in June and July ? 70 of them died." sitting in a dusty house on the edge of his property, He pulled out a notepad that cataloged the demise of his pigs.

"I sold a lot out of panic," he says.

Pig farmers who did not sell watched their pigs succumb to a disease that ate away at their insides in a matter of weeks, often turning the pig's ear blue. In Mr. Liu's barn, he pointed to one pig that was little more than a skeleton, shivering in a corner, struggling for life.

Now, slaughterhouses here go wanting.

"Last year we slaughtered 1,000 pigs a day; now we're doing 100," said Yuan Zi, a manager at the Qiyuan Meal slaughterhouse near the city of Qionglai. "We've laid off nearly half the staff."

Officials in Beijing worry that widespread pork shortages and soaring food prices could prompt panic, unrest or inflation, undermining a sizzling economy.

Trying to contain the damage, the government has announced a series of emergency measures, offering aid, incentives and free vaccines to farmers.

But the government has also warned against price gouging, and vowed to crack down on farmers selling diseased pigs, or injecting a pig with water to bolster its selling weight.

Still, many here say the problem is that pigs are simply in short supply, and it may take months if not a year or two to restock supplies, assuming the disease does not linger, as some scientists say it generally does.

Many experts, meanwhile, worry that China, which the F.A.O. says is the fourth-largest exporter of live and slaughtered hogs, could already be exporting the disease.

"This is already considered to be a threat to the global industry," said Trevor Drew, head of virology at the Veterinary Laboratories Agency in Weybridge, in southeast England. "It would be na?ve to think we could contain this virus."

North Carolina hog farmers are casting a wary eye toward China amid reports of a widespread pig virus there, said Todd See, an extension swine specialist at N.C. State University.

The virus has not spread from China, See said, but it appears to be a strain of blue ear pig disease, or Porcine Reproductive and Respiratory Syndrome, which has been found in North Carolina.
Hog farms already take precautions to guard against the spread of international diseases, such as keeping recent international travelers out of farms. But some worry that a new, more virulent strain of the virus could also develop in the state.
There is an upside for North Carolina pork producers. The epidemic is forcing prices up, which could mean their animals are worth more. "In a way, it could be good for us here," See said. :tiphat: http://www.newsobserver.com/news/story/672103.html

[Rather,] "High Fever Disease" equals blue ear disease [plus] Hog Cholera or PCV2 infection or mycoplasmal pneumonia [plus] secondary bacterial infection.Professor Yang believes that the primary illness of "High Fever Disease," which has broken out across a vast area of China during these 2 years, is blue ear disease. But analysis has shown that this blue ear disease strain, when compared to classic blue ear disease strain, lacks a total of 30 amino acids. Moreover, the source of the strain is unclear. Is it a natural disaster or man-made disaster? No one knows. This disease has spread across a vast area of China, even in Ningxia. And such a high mortality rate is mainly due to the existence of multiple mixed infection with other pathogens, as well as very serious secondary bacterial infections. The main pathogens of the multiple mixed infection are Hog Cholera Virus, PCV2, mycoplasmal pneumonia. The main pathogens of secondary bacterial infection are _Haemophilus parasuis_, _E. coli_, _Streptococcus suis_ type 2, Salmonella, Toxigenic _Pasteurella multocida_, Eperythrozoon, etc.Turning to the prevention and control of "High Fever Disease", Professor Yang believes there are mainly 3 types of situations: pig farms which have not experienced outbreaks, pig farms which had outbreaks, and pig farms [currently] experiencing outbreaks.For a farm that has not experienced outbreaks, the main requirements relate to biological safety measures for the farm itself, including strengthening disinfection in the pig farm's environment, restricting the movement of personnel, prohibiting unauthorized personnel from entering the pig farm, thorough disinfection of hauling vehicles entering the pig farm, and breaking all possible routes of transmission. In addition, they should:- Cease introductions from areas or farms with outbreaks and apply strict inspection;- Manage pig herds with utmost attention and use some nutritional additives toincrease the resistance of pig herds;- Make proper use of medicinal prophylaxis and health maintenance for pig herds;- Control secondary infections in pig herds; and- Immunize pig herds against Hog Cholera, mycoplasmal pneumonia, PRV [Pseudorabies, Aujeszky's disease].Professor Yang did not wish to assess the live and inactivated blue ear disease vaccines now being promoted, and stressed that actual practice is the sole standard for testing truth.For those pig farms which have experienced outbreaks, strengthen pig disinfection, reduce the infection rate of PRRSV in the pig herd and strengthen control of secondary infections. Emphasis should be placed on control of _Haemophilus parasuis_, Streptococcus, _E. coli_, and other secondary infections.For those farms where an outbreak is occurring, disinfection must be strengthened, affected pig sheds closed, personnel movement limited, and other measures taken to prevent expansion of the outbreak. Promptly isolate sick pigs. Dead pigs should be buried or burned for safe disposal to prevent spread of pathogens. In sick pig herds, antipyretics, antibiotics and other drugs should not be used in the early stage. It is recommended to use Chinese medicinal preparations and add electrolytes and vitamins to drinking water. After a week, controlling secondary infections and reducing deaths is the focal point. Add Guangdong Galloper Veterinary Pharmaceutical Company's "Antai" and other dissolvable Western-Chinese medicines to drinking water, [administer] injectable cephalasporins. Immunizations should be suspended in sick pig herds. Porcine [anti]serum can be used to treat sick pigs (at least 30-days post-illness porcine serum; each pig 5ml, twice a day for 2 days with injection into muscle or abdomen). For control of secondary infections, Ceftiofur injections (at 3, 7, 21, 28, 35, and 42 days old) can be used with sucklings and weaners. In addition, antibiotics (such as "Jiakang" [contains Thiamphenicol], Tiamulin, Oxytetracycline, Chlortetracycline, Doxycycline, Amoxicillin) may be added to feed or water.Professor Hanchun Yang's presentation met with the approval and appreciation of many in the audience and society experts. At the symposium, Dr. Changxu Song of the Guangdong Academy of Agricultural Sciences' Veterinary Medicine Institute explained how to set up effective biological safety measures to prevent and control epidemic diseases. Yangcai Lin, vice director of the Institute of Animal Science of Guangdong Academy of Agricultural Sciences, explained how to increase the immune function of animals through nutritional controls.[Byline: Yuhua Cai]--Communicated byroMED-mail Rapporteur Dan Silver[The lecture of Prof. Yang deserves careful reading, especially in relation to 2 salient issues: the multifactorial nature of the syndrome and the (possible) role of vaccines.The involvement of numerous disease agents may be indicative of an immunosuppressive primary pathogen. Such effect by the PRRS virus has been discussed in the past (e.g., Done, S. H., and D. J. Paton. 1995. Porcine reproductive and respiratory syndrome: clinical disease, pathology and immunosuppression. Vet. Rec. 136:32-35).Prof Yang's question "Is it a natural disaster or man-made disaster?" and his reluctance to assess the promoted live and inactivated blue ear disease vaccines, stressing "that actual practice is the sole standard for testing truth", are appreciated and intriguing. One interpretation may lead to a theoretical hypothesis that vaccines may have played some role, either by default or otherwise, in the evolution of this major epizootic. Such a possibility deserves consideration and, possibly, further investigation.The control upon the manufacture of animal vaccines in China, their testing requirements and their licensing and certification procedures, as well as the control upon their application, has been subject to discussions and concern in the past. One example was the Taiwan 1997 outbreak of FMD, suspected to be connected with an attenuated live vaccine virus used in China (see ROYAL SOCIETY INQUIRY INTO INFECTIOUS DISEASES IN LIVESTOCK, 2002<http://www.royalsociety.org/document.asp?tip=1&id=1392>). - Mod.AS]:tiphat: http://tinyurl.com/2jplul

BEIJING, Oct. 29,2007 (Xinhua) --
China has brought blue-ear pig disease under control, Gao Hongbin,
vice minister of agriculture, said at a press conference held here
on Monday.
The disease, which has been on the decline since it peaked in June,
has been checked within all the epidemic outbreak areas, he said.

By Oct. 25, the highly pathogenic disease, also known as
Porcine Reproductive and Respiratory Syndrome, had infected
310,134 pigs in 1,030 epidemic outbreaks in 304 counties
of 26 Chinese provincial areas, of which 81,030 died

Han-Chun Yang: high fever is not just blue-ear disease

日前，在国家饲料工程技术研究中心和广州市饲料办公室主办的“猪病防控技术与抓机遇快速成长研讨会”上，来自中国农业大学的杨汉春教授指出：“高热病”≠蓝耳病，“高热病”=蓝耳病＋猪瘟或猪圆环病毒2型感染或肺炎支原体感染＋细菌性继发感染。 Recently, the national engineering research center feed and feed organized by the Office of the Guangzhou City "Seize the swine diseases prevention and control of fast-growing technology and the seminar", from the China Agricultural University Professor Han-Chun Yang pointed out: "high fever" Blue ≠ ear disease, "high fever" = + Blue-ear disease of swine fever or porcine circovirus type 2 virus infection or Mycoplasma pneumoniae infection + secondary bacterial infection.

杨教授认为，近两年在我国大范围暴发的猪“高热病”，原发病是蓝耳病，但经检测，该蓝耳病毒株与经典蓝耳病毒株相比，共缺失30个氨基酸，而且毒株来源不清楚，到底是天灾还是人祸？ Professor Yang, in the past two years, China's large-scale outbreak of the pig "high fever", the incidence is blue ear disease, but after testing, the Blue ears strain of the virus with the classic blue ears strain of the virus compared to a total of 30 amino acid deletion, and strain sources unclear, in the end is natural or man-made disasters? 谁也不清楚。 Who is unclear. 这场病在全国大范围地传播，连宁夏都有发生，而如此高死亡率，主要还是因为存在与其他病原的多重混合感染，并且细菌性继发感染非常严重。 The disease in the large-scale dissemination, and even in Ningxia have occurred, and such a high mortality rate, mainly because of the multiple pathogens and other mixed infection, and secondary bacterial infection is very serious. 多重混合感染的病原主要有猪瘟病毒、猪圆环病毒2型、肺炎支原体，细菌性继发感染的病原主要有副猪嗜血杆菌、大肠杆菌、猪链球菌2型、沙门氏菌、多杀性巴氏杆菌、附红细胞体等。 Multiple mixed infection of the main pathogens of classical swine fever virus, porcine circovirus type 2 virus, mycoplasma pneumonia, secondary bacterial infection of a major pathogen Haemophilus parasuis, Escherichia coli, Streptococcus suis type 2, Salmonella , Pasteurella multocida, such as Eperythrozoonosis.

谈到对于“高热病”的防控，杨教授认为主要分为三种情况对待：未发生疫情的猪场、已发生过疫情的猪场、发生疫情的猪场。 Turning to the "high fever" of prevention and control, Professor Yang believe that the main treatment is divided into three conditions: no pig farms in the epidemic, the epidemic has occurred pig farms, pig farms in the epidemic. 对于未发生疫情的猪场，首要工作是做好猪场本身的生物安全措施，加强猪场环境的消毒，限制人员的进出和流动，禁止非场人员进入猪场，运输车辆彻底消毒，切断一切可能的传播来源。 The epidemic did not occur pig farms, it is crucial to farm their own biosecurity measures to strengthen environmental disinfection of farms, restrictions on access and movement to prohibit non-farm market access, transport vehicles thoroughly disinfected, and to cut off all the spread of possible sources. 停止从发生疫情的地区或猪场引种，严格检疫。 Stop the epidemic in the region or farms introduced strict quarantine. 精心饲养管理猪群，可使用一些增加猪群抵抗力的营养添加剂，做好猪群的药物预防与保健，控制猪群的继发感染，做好猪群的猪瘟、喘气病、伪狂犬病疫苗的接种。 Pig farmers carefully managed, can be used to increase herd immunity of some nutritional additives to the herd health and drug prevention, control herd of secondary infection, to the herd of swine fever, panting disease, pseudo-rabies vaccine vaccination. 对于现阶段均在推广应用的猪蓝耳病活疫苗和灭活疫苗(高致病性蓝耳病灭活疫苗)，杨教授不予评价，强调实践是检验真理的唯一标准。 At this stage are in the application of pig blue ear disease live vaccine and inactivated vaccines (highly pathogenic blue ear disease vaccine), Professor Yang no evaluation, that practice is the sole criterion of truth.

对于已发生过疫情的猪场，应该加强带猪消毒，降低猪群PRRSV的感染率，强化继发感染的控制，重点应控制副猪嗜血杆菌、链球菌、大肠杆菌等的继发感染。 The epidemic has occurred to farms with pigs disinfection should be strengthened, reducing the herd PRRSV infection, and strengthen the control of secondary infection, the focus should be controlled Haemophilus parasuis, streptococcus, E. coli and other secondary infections. 对于发生疫情的猪场要加强消毒，封闭发病猪舍、限制饲养人员的流动等措施，以防疫情扩散，并及时隔离发病猪只，对死亡猪只应进行深埋或焚烧等无害化处理，防止病原扩散，对于发病猪群，早期不要使用退烧、抗菌等药物，建议使用一些中药制剂，在饮水中添加电解多维，一周后以控制继发感染、降低死亡率为重点。 The outbreak occurred pig farms to strengthen sterilization closed incidence pig sheds, keeping restrictions on the movement of personnel and other measures to prevent the spread of the epidemic, timely isolation and the incidence of pigs should be conducted on the dead pigs buried or burned, and other sound processing to prevent the spread of pathogens, the incidence swine and early not to use anti-fever, anti-bacterial drugs, the proposed use of some traditional Chinese medicine preparations, in addition to drinking water electrolysis multi-dimensional, one week after secondary infection control, focusing on reducing mortality. 饮水中添加一些抗菌药物，可注射头孢类制剂，发病猪群应停止使用疫苗免疫接种，可使用康复猪血清对发病猪进行治疗(发病30天以上的康复猪血清，每头猪5毫升，每天二次，连续二天，肌肉或腹腔注射)。 Add some water antibacterial drugs, injectable cephalosporins agents, the incidence herd should stop using the vaccine immunization, pig serum can be used for the rehabilitation of pig disease treatment (more than 30 days of the onset of rehabilitation pig serum, 5 ml each pigs , the second day, for two days, muscle, or intraperitoneal injection). 对于细菌性继发感染的控制，哺乳仔猪与保育猪可用头孢噻呋针剂(在3、7、21、28、35、42日龄使用)，还可在饲料或饮水中添加抗菌药物(如泰妙菌素、土霉素、金霉素、强力霉素、阿莫西林)。 For secondary bacterial infection control, and conservation of pig suckling pigs available ceftiofur injection (3,7,21,28,35,42-day use), but also in animal feed or drinking water add antibacterial drugs (such as Thai Miao streptozotocin, oxytetracycline, Aureomycin, doxycycline, amoxicillin).

As pigs are susceptible to infection with both avian and human influenza A viruses, they have been proposed to be an intermediate host for the generation of pandemic virus through reassortment. Antigenic and genetic characterization was performed for five swine H9N2 influenza viruses isolated from diseased pigs from different farms. The haemagglutinin (HA) antigenicity of swine H9N2 viruses was different from that of chicken H9N2 viruses prevalent in northern China. Genetic analysis revealed that all five isolates had an RLSR motif at the cleavage site of HA, which was different from those of A/duck/Hong Kong/Y280/97 (Dk/HK/Y280/97)-like viruses established in chickens in China. Phylogenetic analyses indicated that the five swine H9N2 viruses formed novel HA and neuraminidase sublineages that were related closely to those of earlier chicken H9 viruses and were also consistent with the extent of the observed antigenic variation. The six internal genes of the isolates possessed H5N1-like sequences, indicating that they were reassortants of H9 and H5 viruses. The present results indicate that avian to porcine interspecies transmission of H9N2 viruses might have resulted in the generation of viruses with novel antigenic and genetic characteristics; therefore, surveillance of swine influenza should be given a high priority.

The GenBank/DDBJ/EMBL accession numbers for the nucleotide sequences of the H9N2 influenza viruses analysed in this study are DQ981591?DQ981630.
