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。

禽流童仍嚴重 已聯絡明愛80人

【明報專訊】前日(本月2日)確診感染H5N1禽流感的兩歲男童,目前仍在瑪嘉烈醫院傳染病房隔離治療,情况嚴重。衛生防護中心繼續聯絡曾與男童接觸 者,除男童父母外,中心亦對男童曾求診的旺角天一診所、曾乘坐的救護車及明愛醫院醫護調查,至今已聯絡約80人,當中兩名明愛醫院醫護出現呼吸道感染徵 狀,但鼻咽分泌樣本對H5呈陰性反應,調查仍繼續。

中心早前亦對男童父母、兩名於男童求診的私家診所工作的醫護及1名到該診所的病人的樣本測試,對H5禽流感亦呈陰性反應。

漁護署巡全港雞場無異常

衛 生防護中心流行病學調查發現,男童上月20至22日曾前往安徽省,其間並無直接接觸家禽。新華社早前引述廣東省疾控中心流行病研究所所長何劍峰表示,男童 居於廣州市海珠區,發病前一周(5月17日至19日期間),其母曾帶他到居所附近的海珠區南園大街街市,購買一隻即劏活鴨。

中心前日向醫生發信,提醒留意曾在廣州到訪街市或接觸活家禽的病人,並向中心呈報任何懷疑H5個案。另外,中心熱線(21251111)截至昨日中午共收到10宗查詢,全部為市民的一般查詢。

另外,本港漁護署已完成巡查全港30個雞場,未發現異常,所有抽取的樣本對禽流感病毒呈陰性反應,署方表示會繼續監察。

Scientists develop bird flu test kit

Made-In-Singapore H5N1 Bird Flu Diagnostic Kit, which can detect all known strains of H5N1 virus with a single test.

Made-In-Singapore H5N1 Bird Flu Diagnostic Kit, which can detect all known strains of H5N1 virus with a single test.

 

SINGAPORE: Scientists have developed a H5N1 bird flu test kit that can now rapidly detect all existing strains of the H5N1 viruses in a single test with almost 100 per cent accuracy, within a few hours.

The scientists are from the Experimental Therapeutics Centre under the Agency for Science and Technology Research and clinicians from Tan Tock Seng Hospital.

A joint statement by the various parties including A*STAR said the kit was co-developed by Dr Masafumi Inoue, a senior research scientist and project director of Technology Development from ETC and Dr Timothy Barkham, a senior consultant of Laboratory Medicine from TTSH.

This newly launched H5N1 test kit has been clinically validated by several hospitals in Southeast Asia.

Dr Timothy Barkham, senior consultant of Laboratory Medicine at Tan Tock Seng Hospital, said: “The viruses that we’re trying to detect have changed significantly, which would have meant that the old version of the test would not have done a good job if used today.

“The test will help people make the diagnosis which will: (a) help the patient, and (b) treat it properly but also help us make the right infection control decision to stop it from spreading to other people.

“We have to keep checking that the reagents will detect new variations of the virus because the virus changes as time goes by. So although this is an update, we have to keep checking.”

Local small and medium enterprise, AITbiotech, a regional provider of genomic services and molecular diagnostics kits, has recently signed a licence agreement with Exploit Technologies, the technology transfer arm of A*STAR, to market this H5N1 kit regionally.

大陸寧夏固原市爆發H5N1禽流感疫情

中國大陸農業部今天(18日)通報,寧夏省固原市部份養雞場爆發H5N1高致病性禽流感疫情,當地政府已撲殺約9萬5千隻雞。大陸農業部指出,固原市原州區1處養雞場13日發生疑似禽流感症狀,大陸國家禽流感參考實驗室今天確認,固原市當地出現H5N1高致病性禽流感疫情,因此下令大量撲殺疑似染病雞隻。

農業部表示疫情現在已受到控制,而且工作小組也已抵達當地處理疫情,並封鎖疫區。

中國大陸因為是全球養雞數量最多的國家,因此被視為是全球禽流感高爆發疫區之一,而且在鄉村地區,許多雞隻的養殖地點與人類居住地非常靠近,也增加人類感染禽流感的機率。

今年1月,大陸西南部貴州省有1名男子因感染禽流感病毒而死亡,並且也是大陸今年傳出的第二起禽流感死亡病例。

Over half of hospitals yet to complete waste treatment systems

Some 56% of the hospitals in Vietnam have yet to complete their medical waste treatment systems, said Nguyen Huy Nga, head of the Department of Health Environmental Management under the Ministry of Health.

The recent diseases like hand-foot-mouse and H5N1-type influenza A are all concerned with environmental pollution and medical waste treatment, said Nga at the press briefing on Monday in preparation for the seminar named “Environment and health protection” to be held in Hanoi on April 12.

There are currently some 13,600 healthcare facilities nationwide, including 1,300 hospitals. At present, the daily amount of medical wastewater is about 150,000 cubic meters, which will double to 300,000 cubic meters in 2015.

In addition, local hospitals discharge 350-400 tons of solid waste every day, consisting of 40 tons of hazardous medical waste that need to be burnt in incinerators. Therefore, the demand for medical garbage treatment in Vietnam is very huge and is becoming an urgent need.

Catherine Galtier at APB France Environment Vietnam said expenditure is the primary difficulty of completing medical waste treatment systems at local hospitals. The hospitals have yet to include the expenses for waste treatment in their budget estimates and neglect this issue during their operations.

Regarding the investment in medical waste treatment, Nga said the capital can be sourced from credit funds, the State budget and others. Lately, the Government has allowed the health ministry to borrow some US$150 million for investment in waste treatment, in which US$140 million will be used for building waste treatment systems at the hospitals and US$10 million for developing policies and observatory systems.

One of the greatest challenges for environment and health protection is that about 50% of the households in rural areas lacks sanitary latrines. Even the already-constructed latrines have yet to meet the technological standards.

Related agencies and French experts hoped the situation would be remedied when the environment improvement technology that has been successfully applied in France is introduced in Vietnam at the upcoming seminar to be organized by the French Embassy in Vietnam and French International Trade Agency (Ubifrance).

美國生物安全委員會建議禽流感病毒研究全文公開


美國生物安全委員會建議禽流感病毒研究全文公開

 

By sonia

美國國家科學生物安全咨詢委員會(NSABB)經審查後,改變原先決定,認為關於H5N1禽流感病毒變體的兩篇具有爭議性的科學論文發布不會造成直接危險,應該毫無保留地予以發表。

《科學》編輯去年曾在聲明中表示,發表在《科學》和《自然》的兩項研究論文,即美國威斯康辛大學Yoshihiro Kawaoka修訂的禽流感論文,以及荷蘭伊拉斯馬斯醫學研究中心 Ron Fouchier的第二篇論文,為了避免信息落入不法之徒手中,自去年12月以來被停止,美國政府要求出版商審查兩項研究的細節。

流感研究人員一月份時還自願暫停60天,空出時間讓監管機構對這兩篇禽流感的論文進行國際範圍討論。委員會在上周五的一份聲明中表示,“數據提供的信息不會馬上被用以對公眾健康和國家安全造成禍害的危險性研究。全球合作的前提是自由的信息共享,也是評估這些文稿的基本原則。”並以提交美國政府審批。

委員會一致投票通過Yoshihiro Kawaoka修訂的禽流感論文全文發表,並以12比6的投票通過Fouchier第二篇論文的數據,方法和結論予以發表。

H5N1禽流感病毒對禽類是致命性的,但不易在人與人之間進行傳播。盡管,Fouchier和Yoshihiro Kawaoka的研究表示H5N1病毒的變異菌株在雪貂間有更大的傳染性,有可能會在人體中傳播。

研究目的旨在表明病毒如何發生突變並導致人群中快速傳播,從而為科學家和衛生官員提供更多信息以防止禽流感疫情。

委員會的修改建議使得其與世界衛生組織的觀點靠近,他們曾在二月份建議兩篇論文全文發表。

美國國家科學生物安全咨詢委員會是聯邦監管機構獨立的咨詢委員會,兩篇論文還需要同行進行評審,美國政府還沒有下最終的定論。
