H7N9 bird flu comes home to roost in China

The handful of poultry dealers lingering at Chengbei Market have had little to do since Chinese authorities shut down their livelihoods after H7N9 bird flu began stalking the country again, killing scores of people this year.

They spend their days counting the losses to their business, gambling at cards and cleaning the cages which once held thousands of live birds, hoping the government will allow the trade to resume.

“The chickens lay every day and I can’t sell the eggs. We are losing money,” said Li Guiying, local boss of the Xuancheng Shandi Poultry Co.

H7N9 avian influenza has returned to China with a vengeance, sickening 226 people and killing 72 so far this year, as the government girds for what is likely to be a long battle to contain what one World Health Organization (WHO) official has labelled an “epidemic”.

China has responded by aggressively closing down poultry markets in locations believed to be at threat from the virus, raising an outcry from the agricultural industry and consumers with a taste for freshly slaughtered food.

But in the longer term the government needs to encourage a shift in behaviour of consumers and clean up the nation’s food supply chain, experts say, which has been hit by a series of health safety scandals.

Ultimately, fears exist that the H7N9 virus could mutate and become easily passed between people, rampaging through the world’s most populous country and crossing its borders to spread around the planet.

After subsiding following the first outbreak early last year, H7N9 resurfaced in the autumn, then boomed. The figures for the first two months of the year exceed the tallies of 144 infections and 46 deaths for the whole of 2013.

The WHO and Chinese authorities maintain there is no evidence of “sustained” human transmission with H7N9, though there have been cases of family members in close contact infecting each other.

But they acknowledge a seasonal spike in cases, possibly caused by the affinity of the virus for colder temperatures and humans’ greater susceptibility to illness in winter.

“The big question always is, ‘does it go down as the season goes away or does it continue?'” said the WHO Representative in China, Bernhard Schwartländer.

“We seem to start seeing a decrease again, which confirms the seasonal patterns, but there is of course no reason and no space to relax,” he said.

– ‘Chickens can’t talk’ –

Poultry dealers accuse the government of shutting the markets without scientific evidence and demand compensation for the birds they were forced to slaughter or sell at rock-bottom prices.

“Chickens can’t talk. Ducks can’t talk. We don’t know where bird flu came from: chickens, ducks or other birds,” said Li, at the Chengbei market in Hangzhou.

Authorities in the city, capital of the eastern province of Zhejiang, the centre of the current outbreak, shut down the market in January. The province has announced radical plans to ban — forever — all live poultry trading in urban areas, according to state media, and replace it with factory-slaughtered and frozen meat.

China’s National Poultry Industry Association estimates the sector has lost more than $3.0 billion so far this year, on top of the impact of the outbreak last year as consumers shunned fowl and markets stopped business.

“Within the industry we call it a devastating hit, a crowning calamity. With our backs to the wall, it seems one cannot adequately depict the severity of the situation,” said the association’s secretary general Gong Guifen.

“The selling of frozen chicken is more like an emergency response, whereas the industry as well as the public’s consumption habits cannot be changed overnight,” she said.

But poultry market closures were the most important measure to contain the virus, said WHO’s Regional Director for the Western Pacific Shin Young-soo.

“Of course, I think the Chinese government should consider many other things. This has a huge impact on our daily life… on farmers, market people,” he said.

In contrast to H5N1, a different strain of avian influenza which affected China earlier, H7N9 is harder to detect because it does not kill the birds that can pass it to humans, he pointed out.

“H7N9 is more difficult because actually the bird and ducks, they’re… not really sick. It’s more difficult to control,” he said.

“It’s very fatal to human beings,” he added. “We know that this virus (is) never going again. It’s coming back.”

First N America H5N1 bird flu death confirmed in Canada

China has been vaccinating poultry against the H5N1 virus

Canadian health officials have confirmed the first known fatal case of the H5N1 avian influenza strain in North America.

Canadian Health Minister Rona Ambrose said the deceased person was an Alberta resident who had recently travelled to Beijing.

Calling the death an “isolated case”, Ms Ambrose said the risk to the general population was low.

Ten people have died in Alberta this season from swine flu, or H1N1.

H5N1 infects the lower respiratory tract deep in the lung, where it can cause deadly pneumonia.

The World Health Organisation (WHO) says it is difficult to transmit the virus from person to person but when people do become infected, the mortality rate is about 60%.

In the latest incident, the infected person first showed symptoms of the flu on an Air Canada flight from Beijing to Vancouver on 27 December, officials said.

The passenger continued on to Edmonton and on 1 January was admitted to hospital where they died two days later.

Canadian federal health officials said they would not identify the patient’s sex, age or occupation.

Ms Ambrose said Canadian officials were working with Chinese authorities on the case.

“The risk of getting H5N1 is very low. This is not the regular seasonal flu. This is an isolated case,” she said.

According to the WHO, between 2003 and December 2013 there were 648 confirmed human cases of H5N1 infection in 15 countries, leading to 384 deaths.

Experts say that if the H5N1 virus were to mutate and become easily transmissible between humans, the consequences for public health could be very serious.

Cambodia reports 14th human case of bird flu this year – Xinhua | English.news.cn

PHNOM PENH, July 12 (Xinhua) — A three-year-old boy from Cambodia’s eastern Prey Veng province has been confirmed positive for the avian influenza H5N1, bringing the number of the cases to 14 so far this year, a joint statement by the World Health Organization and Cambodian Health Ministry said Friday.

Only five cases out of the 14 cases this year survived.

The 14th victim was confirmed positive for H5N1 on Wednesday, the statement said, adding that the boy was admitted to the Kantha Bopha Hospital with fever, dyspnea and cough Monday. “At the hospital, he was treated with Tamiflu and is currently in stable condition,”it said. “There were recent deaths among poultry in the village and the boy was likely to be exposed to sick and dead poultry before he became sick,”it added.

Avian influenza H5N1 remained a serious threat to the health of all Cambodians, Health Minister Mam Bunheng said. “Children also seem to be most vulnerable and are at high risk because they like to play where poultry are found,”he said in the statement.”I urge parents and guardians to keep children away from sick or dead poultry and make sure children wash their hands with soap and water after any contact with poultry.”

H5N1 influenza is a flu that normally spreads between sick poultry, but it can sometimes spread from poultry to humans, the statement said, adding that it is a very serious disease that requires hospitalization.

Cambodia sees the worst outbreak of the virus this year since the disease was first identified in 2004. To date, the country has recorded 35 human cases of the virus, killing 28 people.

Since 2003, there have been 633 laboratory confirmed human cases of H5N1 virus globally with 376 related deaths, the statement said.

农粮与兽医局表示,我国没有从印度尼西亚进口家禽,目前不受禽流感病毒影响。

农粮与兽医局表示,新加坡没有从印度尼西亚进口家禽,目前不受禽流感病毒影响。

农粮局是针对印尼发现新种H5N1禽流感病毒后,在社交网站Facebook的页面上,表示这点。

当局说,已经采取预防措施,包括:禁止从爆发禽流感的国家进口家禽和相关产品、在入境处严格监控进口的家禽和鸡蛋,确保新加坡不受禽流感病毒影响。

较早前,印度尼西亚发现新种H5N1禽流感病毒。

印尼农业部宣布,爪哇多个地区的农场近日有30多万只鸭死亡,当局发现病源属于H5N1病毒的新分支。

农业部表示,有必要研究病毒基因,以确定它是否来自外地,或是属于新变种。他们怀疑新病毒可能来自越南或泰国。

卫生部人员要求地方政府,为摩托车和货车消毒,设法阻止病毒扩散,因为这两种交通工具通常用来运载家禽。

尼泊尔爆发禽流感疫情 鸡和鸡蛋被销毁

一名政府官员称,尼泊尔当局周一销毁了数百只鸡和鸡蛋,因为禽流感(H5N1病毒)正在袭击首都加德满都。

政府官员说,在H5N1型禽流感被检测出后,加德满都郊外的家禽农场大量的鸡被扑杀。2011年12月,在尼泊尔首都加德满都第一次检测出禽流感病毒;2月份,在尼泊尔东南部再次发现了H5N1病毒。

据法新社报道,动物卫生局高级兽医官纳拉扬·普拉萨德·吉米雷说,“大约1200只家禽农场的鸡死于H5N1病毒,我们捕杀了剩余的800只鸡,并销毁了数以千计的鸡蛋。”政府官员说,卫生工作者还在监测受感染的地区。

H5N1病毒,也被称为禽流感,通过鸟类与人类的直接接触传播, 许多研究人员担心,这种病毒可能会变异成更致命的菌株,很容易在人与人之间传播。和鸡一起工作的农民以及其他工作人员,来本国旅游的外国游客都遭受了禽流感的袭击。那些接触到受感染家禽肉类、吃生或未煮熟的家禽肉类、鸡蛋或受感染家禽血的人,最有可能感染这种病毒。

禽流感的相关症状包括发烧,呼吸困难,腹泻,甚至死亡。

Girl, 8, who visited Singapore dies of H5N1


An Indonesian girl who travelled with her family to Singapore died from the H5N1 avian flu shortly after returning to Indonesia.

The 8-year-old developed a fever a day before her trip to Singapore and visited a doctor here.

She was here with her family for six days from June 19 to June 24 with her mother and some relatives, according to details released by the Ministry of Health (MOH) to the media.

She stayed in a hotel here, but the ministry declined to reveal which hotel it was. Her condition worsened after she returned and she was diagnosed with the avian flu on June 29.

The child had reportedly carried freshly killed chickens with her father earlier last month, on June 12.

As a precautionary measure, the MOH has started contact tracing and hospitals have been alerted to the case.

Her aunt who resides and the general practitioner who treated her are both fine, reported The Straits Times.

Hospitals such as the National University Hospital said their emergency medicine departments have been alerted and will look out for patients with flu-like symptoms such as fever, cough, sore throat, chills, body ache, headache and vomiting.

There have been no local cases of H5N1 reported to MOH, and it said  chances of transmission between humans are extremely low.

香港鸟市发现H5N1禽流感病毒

香港当局7月5日表示他们关闭了一个著名的旅游景点,原因是在该地区的鸟园展览中发现了致命的禽流感病毒。

香港渔农自然保护署下令,繁忙的旺角区园圃街花鸟市场将关闭21天,从7月5日(星期四)开始执行。


香港渔农自然保护属下令,繁忙的旺角区园圃街花鸟市场将关闭21天,从7月5日(星期四)开始执行。

 

该部门在对这地区的禽流感常规监测中,发现一家宠物鸟店里养有的东方喜鹊异常,经检测发现禽流感病毒。政府随即下达关闭命令,并处理了宠物店里的所有鸟类。目前,香港官员们仍在调查禽流感病毒出现的原因。

香港卫生防护中心总监曾浩辉在新闻发布会上表示,宠物鸟类向人传播病毒的风险相当低。但 健康专家提醒人们,大多数人的感染是因为直接接触受感染禽鸟而引发的,应尽量避免接触野生雀鸟,家禽和它们的粪便,一旦与这些动物接触后,要彻底清洁双手。

自1997年以来,香港在家禽中偶尔出现过几宗禽流感病例,但没有爆发重大疫情。1997年的疫情是由于禽流感病毒变异,造成6人死亡,数百万只鸡被销毁。据法新社报道,当年6月份,中国南方城市也出现了首例H5N1人感染禽流感病例。

该病毒已经导致全世界330人死亡,印尼是受感染最为严重的的国家,2012年有8人受感染死亡。特别受关注的是香港2003年非典大疫情,期间导致300人死亡。

H5N1型高病原性禽流感病毒(圖:取自維基百科)

中國大陸農業部2日晚間表示,新疆爆發H5N1型禽流感疫情,當地有關部門已經撲殺超過15萬隻雞。

大陸農業部說,新疆於6月20日出現禽流感疫情,初步造成1,600隻雞死亡、約5,500隻雞生病,目前只證實屬於H5N1型禽流感;為了控制疫情,農業部門封鎖了相關區域,並且撲殺了15萬6,439隻雞。

大陸農業部和國營媒體都沒有說明確切的疫情發生地點,但表示,疫情出現在由新疆生產建設兵團經營的1座農場。根據大陸國營媒體,這個兵團屬於半軍方的政府組織,擁有250萬人。

中國大陸擁有全球數量最多的禽鳥,而且在農村地區,雞隻和人類互動密切,中國大陸因此被認為是禽流感散播風險最高的國家之一。

中國大陸上回通報出現禽流感疫情是在4月間,當時寧夏約有9萬5,000隻雞死亡。

6月初,香港有1名男童被確診感染禽流感,這是18個月來的首例人類感染個案。這名男孩與父母、外婆長期在廣州海珠區居住。

香港H5N1禽流感 證實為禽傳人

【聯合報╱記者黃文彥/即時報導】

2012.06.06 12:50 am

香港於上周確認一例H5N1禽流感個案,分析後證實感染原來自禽鳥,且相關接觸者鼻咽試紙均呈陰性反應。

一名居住於中國大陸廣東省珠海區的男童於上周五在香港檢出H5N1病毒;由於香港已近兩年為曾爆發H5N1禽流感,因此引發高度重視。

初步調查發現,男童曾於5月中到過居家附近的活禽市場,且病毒分析後發現,本病例與去年及今年從野鳥分離的病毒相同,因此研判病毒基因來自禽鳥。

此外,檢測男童父母及5名接觸者後,並未發現鼻咽試紙呈現陽性。

因應此次疫情,台灣也隨即啟動防治機制,包含加強機場發燒旅客篩檢等措施。

2003年迄今,全球已累計604例H5N1禽流感,並造成357人死亡,其中中國大陸確診42例,有28人死亡。
