greek bird flu case confirmed
european union officials say bird flu had been found on one of the greek isles and tests were being conducted to determine if it is the deadly h5n1 virus.
the european commission said monday greek veterinary authorities had informed it of a suspected case of avian influenza on the island of inousses, based on a serological test that proved positive for the presence of avian influenza h5 antibodies.
the samples were in the process of being sent for confirmation and virus isolation tests at the greek national reference laboratory in thessaloniki, and the european commission said it had requested that samples also be sent immediately to the community reference laboratory in weybridge, england.
the commission said it is preparing to ban the movement of live poultry and poultry products from the infected area in the chios region.
the eu said its ban would be adopted as soon as the greek national reference laboratory confirmed the results, expected tuesday.
the eu said following consultations between the commission and the greek ministry of agriculture, greek authorities had agreed to restrict the dispatch of live poultry and poultry products as a precautionary measure.
monday afternoon the mayor of the island of chios said a farmer on nearby inousses who raises turkeys and chickens noted on thursday that some of his birds had died.
two state veterinarians were sent in to look at nine turkeys. they also took blood samples from some chickens.
the mayor said a state lab in athens confirmed monday afternoon that one of the nine samples proved positive for an h5-type virus.
the romanian government confirmed saturday that the h5n1 strain of avian influenza had been confirmed in romania, the first instance of the lethal strain known to have reached europe.
a statement posted on the government web site said the strain had been confirmed. its existence in romania bolsters the theory that the virus may be spread by migratory birds.
on thursday, the european union said the h5n1 strain had been confirmed in turkish poultry, and said the virus "is h5n1 closely related to a virus detected in a wild bird in central asia a few months ago."
the eu said then that the strain likely would be found in romania, and the european commission said it would ban imports of live birds, poultry meat and other products from romania. imports of live birds and feathers from turkey were banned earlier in the week.
despite the fact that 117 people in asia have been infected by the strain and 60 have died, h5n1 in its current form does not easily infect humans.
however, officials fear it could mutate into a more easily transmissible strain and result in a global pandemic.
希腊宣布发现首例禽流感病例 禽流感蔓延欧洲
希腊农业发展和食品部部长巴西亚科斯17日正式宣布,希腊境内发现了首例禽流感病例,当前已经确定是h5型病毒株,还在进一步化验是否是毒性较强的h5n1型病毒。希腊成为该地区继罗马尼亚和土耳其之后第三个发现禽流感病例的国家。
巴西亚科斯说,爱琴海东部地区奇欧斯岛(chios)上的一位农民,本月13日向政府报告说,他的小型农场上饲养的火鸡最近出现了一种可疑的症状,类似禽流感。当地流行病服务中心立即派出两名兽医从已经死亡的火鸡身上提取了9个样品,送往雅典流行病研究中心进行检验,结果发现其中一个样品的h5呈阳性。而土耳其发现的是禽流感中的h5n1病毒。
巴西亚科斯还说,政府将再次提取样品,送到最权威的萨洛尼卡流行病研究中心进行分析检验,以确保检验结果准确无误。
除了希腊,希腊北方邻国马其顿也发现上千只病死鸡,一旦证实是禽流感,那么显然禽流感传播速度已经超过专家预期。另外,克罗埃西亚也发现10多只鸟暴毙,欧盟紧急下令检验是否感染禽流感。
在此同时,罗马尼亚禽流感疫区多瑙河三角洲地区的马留克村,17日又有12只天鹅被检验出禽流感;多瑙河三角洲是候鸟从俄罗斯迁徙到北非的必经之地。当前疫情有向西欧蔓延的趋势,各国防疫专家不敢掉以轻心,正在边境做好监护措施,杜绝禽流感入侵。
欧盟宣布早些时候在土耳其发现的禽流感品种就是h5n1类型的,土相关部门开始扑杀大量家禽。 据土耳其媒体援引该国农业和农村事务部部长13日的话报道说,自本月9日土卫生部门确认西北部巴勒克埃西尔省发生禽流感疫情以来,土相关部门已经在该地区建立了隔离区,并扑杀了大量被怀疑感染禽流感病毒的家禽。
据悉,专家在土耳其西北部的一个农庄发现的死鸟身上搜集了样本,进行了有关的病毒化验。据英国广播公司报道,欧盟卫生事务专员基普里亚诺说,现在的假定是,近日在罗马尼亚发现的禽流感病毒可能也是h5n1类型。who表示,世界动物卫生组织(oie)化验结果显示,土耳其禽流感为h5n1高病原性,罗马尼亚则确定为h5次型禽流感,但是否为高病原性仍待进一步检验。欧盟方面已经采取措施,禁止从罗马尼亚进口鸟类和家禽制品。
自从今年底,h5n1流感病毒已经在亚洲地区导致60人死亡。不过,在众多病例中,只有一例可能是从其他病人身上感染的。到目前为止,专家认为,h5n1禽流感病毒主要通过人类与病鸟、死鸟紧密接触传播,人传人的机会目前不大。但是 who表示,h5n1禽流感扩散到新地区的禽类,增加了人类进一步感染的机率,令人忧虑。
欧盟卫生事务专员基普里亚诺在一个记者会上说,他建议有关方面为那些可能受感染的人注射流感疫苗。他同时说,政府要集虑准备大量抗病毒药物。
不过就在欧盟拉警报之际,世界卫生组织发言人科丁利17日呼吁,欧洲地区传出禽流感h5n1病毒入侵后,造成欧洲地区很大的焦虑,导致各国政府将焦点放在各自的准备工作,但是“忘了原爆点是在东南亚”,他警告,世人关注禽流感疫情发展焦点不应该从东南亚转移到欧洲,但其实最有可能爆发大规模人传人,禽流感的地方还是在东南亚。
