Bird flu may mutate to human form in Indonesia: FAO
MILAN (Reuters) - The bird flu virus, widespread in Indonesia, could mutate and cause a human influenza pandemic, the United Nations' Food and Agriculture Organization (FAO) said on Tuesday.
\"I am deeply concerned that the high level of virus circulation in birds in the country could create conditions for the virus to mutate and to finally cause a human influenza pandemic,\" FAO Chief Veterinary Officer Joseph Domenech said in a statement.
Avian influenza mostly attacks birds but its deadly H5N1 strain has killed 235 people around the world among 372 known cases since its outbreak in 2003 in Asia.
\"The human mortality rate from bird flu in Indonesia is the highest in the world and there will be more human cases if we do not focus more on containing the disease at source in animals,\" Domenech said.
Bird flu has hit 31 out of 33 provinces of Indonesia with an endemic virus in Java, Sumatra, Bali and southern Sulawesi and sporadic outbreaks reported in other areas, Rome-based FAO said.
Despite major control efforts, Indonesia has failed to contain the spread of bird flu in poultry in the country where about 20 percent of 1.4 billion chickens are scattered in around 30 million backyards, Domenech said.
\"We have also observed that new H5N1 avian influenza virus strains have recently emerged, creating the possibility that vaccines currently in use may not be fully protecting poultry against the disease,\" he said.
A highly decentralized administration, under-resourced national veterinary services, thin international and national financial and human resources for control campaigns are among the major problems that Indonesia has to deal with in fighting the virus spread, he said.

米兰(路透社)- 在印尼流行的禽流感病毒,可能变异并引起人类流感大爆发,联合国食品农业署在周二发布消息。
“该国禽类高水平的病毒流通为病毒变异创造条件,可能最终导致人类流感爆发,对此我深表关注。”食品卫生署的首席兽医官员Joseph Domenech声明。
禽流感病毒主要攻击禽类,但它致命的H5N1亚型自从2003年在亚洲爆发以来,已经导致全球372例病例,其中致死235人。
“印尼的禽流感导致的人类死亡率是全球最高的,如果我们不在动物源头上控制该疾病,将会有更多人受到感染。”
印尼33个省份中有31个出现禽流感疫情,在爪哇、苏门答腊、巴厘和苏拉威西南部有局部爆发,而在其他地区也有零星爆发的报道,罗马的食品农业署说。
尽管付出极大的努力,印尼控制国内家禽间的禽流感病毒扩散的工作还是失败了,因为14亿只鸡有20%分散在3000万个养殖场中,Domenech说。
“我们已经观察到最近出现了新的H5N1禽流感病毒亚型,可能使当前使用的疫苗难以全面保护家禽免受感染。”
高度分散的管理,国家兽医服务匮乏,薄弱的国内外经济和人力资源是印尼控制病毒扩散面对的主要问题,他说。
联合国粮农组织说,尽管印尼政府和国际社会已采取多重防控措施,但仍无法有效控制印尼的禽流感疫情。该组织担心,在印尼广泛传播的禽流感病毒可能变种,引起大规模的人类流行性感冒。
总部设在罗马的联合国粮农组织首席兽医官多梅内奇昨天发表声明说,他们已在印尼193个地区部署了监察与反应小组,但是在当地33个省中,仍有多达31个省出现禽流感疫情,包括爪哇、苏门达腊、峇厘和南苏拉威西省等。
禽流感在印尼扎根的情况令人担忧。多梅内奇说,印尼现已是全球人类感染禽流感死亡率最高的国家,如果不加强管制,从动物的源头遏制疫情扩散,人类感染禽流感的病例将会增加。印尼全国有14亿只鸡,其中20%鸡只散布在3000万个后院中饲养。
另外,多梅内奇也警告说,最近已出现了新的H5N1禽流感病种,这意味着,现有的流感疫苗可能不足以保护禽类免受病毒的感染。

他说:“我非常担心,禽流感在印尼高度流行的情况,可能制造让病毒变种的条件,以致最终引起大规模的人类流行性感冒。”
多梅内奇指出,目前最重要的挑战是,立即实行其他国家有效控制禽流感疫情的主要策略,这些包括有效的监督机制、紧急扑杀与赔偿、为禽类注射疫苗、加强生物安全系统、建立有效的实验室及隔离措施以及控制禽类和其产品的流动性。
禽流感自2003年在亚洲爆发以来,全球共有373起确认感染H5N1病毒的病例,其中236人丧命。
寮国爆发新一波禽流感疫情
在这同时,寮国外交部昨天也证实,西北部地区靠近中国和缅甸的边界处,爆发新一波禽流感疫情。
外交部发言人詹塔朗希说,疫情发生在琅南塔省的一个乡村里,有100只鸡因感染H5N1病毒而死。政府已迅速在乡村方圆3公里的范围内,扑杀800只鸡。当地政府至今并未接获该区有人染病的报告。 |
