H5N1为RNA病毒,是禽流感的一种亚型。流感病毒颗粒外腊由两型表面糖蛋白覆盖,一型为植物血凝素(即H),一型为神经氨酸酶(即N),H又分16个亚型,N分9个亚型。所有人类的流感病毒都可以引起禽类流感,但不是所有的禽流感病毒都可以引起人类流感, 现在已经确认能够感染人的禽流感病毒共有8种,包括H5N1、H5N2、H7N2、H7N3、H7N7、H9N2、H10N7,以及最近的H7N9。其中H5为高致病性,H5N1为卫生部新传染病防治法中规定报告的法定传染病,又称人感染高致病性禽流感。禽类流感根据其致病性可分为高致病性和低致病性。H5N1为高致病性禽流感病毒,1997年,首次从中国香港一3岁儿童的流感死亡病例标本中分离鉴定出。

    1病毒历史

    编辑本段 回目录

    在过去100年间,给人类带来巨大灾难的病毒有三种,分别是:导致西班牙流感的H1N1型,导致亚洲流感(1957年)的H2N2型,以及导致香港流感(1968年)的H3N2型。H5N1型是堪与它们相提并论的强毒型病毒,值得予以警惕。

    构成流感病毒遗传基因的核糖核酸的突然变异,比人体脱氧核糖核酸要快100万倍。此前,大约每隔10—40年就会出现一种高致病性病毒。病毒平均每年有10次突然变异,30年就有300次,大概在300次突然变异中,就有一次变成强毒型。

    2病毒起源

    编辑本段 回目录

    流感病毒起源早于脱氧核糖核酸。在30—40亿年前就存在核糖核酸世界(由核糖核酸司职遗传的世界),有一种学说认为,流感病毒是那个时代产生的化石级产物。不过据说当下流行的流感病毒源是鸭子,出现于200—300年前。与其类似的病毒在蚯蚓身上也存在,在自然界更是广泛存在。它在最初的宿主体内还相安无事,一旦超越种类感染其他宿主,它便突然具有强毒性,开始作恶。

    H5N1型病毒已在鸡群中流行,如果它感染猪或人,其繁殖速度将迅速变快。

    3新型变异

    编辑本段 回目录

    联合国粮农组织与2019-05-23指出,H5N1这种可以通过家禽传染给人类的高致病型禽流感病毒在最近几年有不断扩散的趋势。 粮农组织首席兽医官员卢布罗夫指出,近几年H5N1禽流感病毒传播有扩散的趋势,而且在中国和越南还出现了H5N1变种病毒,能使现有疫苗失去作用。他呼吁各国做好准备,对病毒进行密切监控,防止疫情蔓延。

    卢布罗夫指出,鸟类移徙是造成H5N1禽流感病毒传播的罪魁祸首,家禽的生产和销售也促使了H5N1的传播。他还指出,在过去两年里,这种病毒通过鸟类长途移徙传播到了曾经根除此种病毒的国家。

    卢布罗夫同时还对在中国和越南出现的H5N1变种病毒表达了担忧。他指出,这种变种病毒能够抵御现有疫苗的作用,呼吁相关国家不要掉以轻心,应做好充分准备,对这种病毒加以监控。

    病毒学家周二警告称,尚无疫苗可防治在中国和越南传播的H5N1禽流感变异毒株,呼吁各界加强对该病毒的监控,以免传染人类。

    联合国粮农组织(FAO)警告称,禽流感可能再度席卷而来,并称H5N1禽流感变异毒株正在亚洲及其它地区传播。

    科学家尚不确定新病株H5N1-2.3.2.1是否对人类更致命,但他们指出,该病株与原先病毒差异较大,人类针对原先病毒而研制的疫苗对其无效。

    香港大学病毒学家佩里斯(Malik Peiris)说道:“目前,世界卫生组织(WHO)推荐了一种人用的H5N1备选疫苗……但它无法全面防治(新毒株)。”

    “不过这很常见。H5病毒不断发生变化,因此我们也必须研发新疫苗来应对。”

    据英国广播公司20日报道,美国政府要求两份知名科学期刊不要透露科学家如何在实验室制造出致命禽流感病毒H5N1的相关细节,担心被人利用制造生物武器。

    《科学》与《自然》期刊准备发表荷兰一家实验室制造出H5N1病毒的详细研究报告。

    美国政府的一个委员会说,担心研究报告可能被用来协助制造生化武器。

    但是,该委员会同意两家期刊可以发表研究报告的非敏感内容,以帮助科学家监视禽流感病毒的自然进化并研究有效治疗方法。

    H5N1病毒可以致命,但是到目前为止只有350人被确认死于这种病毒。这主要是因为H5N1病毒不能在人与人之间传播。

    4病毒病例

    编辑本段 回目录

    1、1997年8月,香港报告了全球首个感染H5N1禽流感病毒死亡的病例,死者是个3岁男孩;在那次的禽流感爆发中,共有18个人受到传染,6人死亡,香港杀鸡150万只;

    2、2003年2月,香港再次出现H5N1病毒,两人受到传染,一人死亡;

    3、2003年12月,越南出现第一个人感染H5N1病毒死亡病例,死者是个8岁女孩。至今越南已经有92人受到传染,42人死亡,是所有受影响国家里受传染和死亡人数最多的;

    4、2004年1月,泰国报告第一个禽流感死亡病例,死者是一个六岁男童。泰国共发生人感染禽流感病例20例,死亡13人;

    5、2005年7月,印尼出现首个人感染禽流感死亡,死者是一个38岁的男子、以及他的两个分别为1岁和9岁女儿。印尼至今已经有9个受感染病例,5个人死亡。

    6、从2004年12月,柬埔寨报告了四个人受感染的病例,四人死亡。

    7、2012年9月,广东省湛江市经济技术开发区发生1起家禽H5N1亚型高致病性禽流感疫情。发病鸭14050只,死亡6300只,对67500只家禽全部进行扑杀和无害化处理。

    8、2019-05-23,韩联社援引朝鲜中央通讯社报道,朝鲜中央兽医防疫所和农业科学院兽医学研究所等于2019-05-23查明,平壤斗团养鸭场由于鸭子和染病的候鸟接触而发生了高致病性H5N1禽流感疫情。朝鲜已通知联合国粮农组织(FAO)和世界动物卫生组织(OIE)等国际机构,并屠宰了超过16万只鸭子。报道指出,朝鲜媒体报道相关事实还是首次。

    北美现首例H5N1禽流感死亡病例

    加拿大卫生部部长罗娜·安布罗斯8日证实,加拿大艾伯塔省一名居民因患H5N1型禽流感3日死亡。这是北美地区首例H5N1型禽流感死亡病例。

    5诊断

    编辑本段 回目录

    世界动物卫生组织(OIE)规定,禽流感病毒的检测采用鸡胚病毒分离培养及致病力测定。中华人民共和国国家质量监督检验检疫总局和国家标准化管理委员会联合发布了6项有关禽流感病毒检测的国家标准,其中针对H5N1亚型的有《H5亚型禽流感病毒荧光RT-PCR检测方法》、《H5亚型禽流感病毒NASBA检测方法》。美国CombiMatrix 公司研制一种基于半导体的DNA芯片,芯片上有针对A型流感病毒所有亚型的血凝素和神经氨酸酶的特异性寡核苷酸探针。检测时,先将病毒的遗传材料进行PCR扩增,再与芯片杂交,能在4小时内检测出流感病毒株系。

    6预防

    编辑本段 回目录

    H5N1的防治最有效的方法是研制疫苗。WHO推荐以H5N1原型的病毒株作为研制疫苗用病毒株。荷兰的Akzo Nobel NV和美国葛兰素史克公司研制人H5N1禽流感病毒疫苗。

    7治疗

    编辑本段 回目录

    有实践证明,对人感染H5N1治疗有效的药物是Roche公司生产的口服胶囊达菲(病毒神经氨酸酶抑制剂)。动物实验证明可抗H5N1的药物还有中国农科院兰州畜牧与兽药研究所、农业部新兽药工程重点试验室主任梁剑平博士领导的课题组研制的金丝桃素、云南农业生态研究所研制的那氏一号。

    越南国立卫生和流行病学研究院从一名患者体内分离到了抗达菲的H5N1的病毒株,动物试验表明,美国葛兰素史克公司生产的喷雾剂“乐感清”(Relenza)却对这种变异病毒有效果。

    8最新病例

    编辑本段 回目录

    2019-05-23夜间,四川省卫生和计划生育委员会官方网站发布消息称,该省成都市确诊1例H5N1病例。目前,患者病情极其危重,四川省相关专家组正在全力抢救。
