    2) The positive rate of blood sera of H5 was up to 97.7% and that of H9 was 98.5%. Among them, there was little difference on positive rate of H5 both between migratory birds and resident ones, and among those from three different sources and so did H9. Therefore, we concluded: 1) It exited the possibility to transmit AIV as releasing captive bird to field.
    2)血清检测中H5的总阳性率为97.7%,而H9达98.5%,其中,不论是候鸟与留鸟间,还是放生个体、市场个体及野外个体间在H5差异不大且都高于94%,H9也是如此。 由此,我们认为:1)鸟类放生存在传播禽流感的可能性;

We sampled wild birds for the Avian Influenza Virus (AIV)(H5, H7 and H9) survey in the AI infected regions of Guangdong during its eruptive period in early 2004. Seventy-six samples of blood serum, 125 swab samples and 21 organic samples were collected. The method of agar gel precipitation (AGP) and hemagglutination inhibitory (HI) was adopted in serum detection. The chicken embryo culture was adopted in virus detection. Our results showed: (1) H9 viruses were only found in starlings of Nan'ao, Shantou,in the...

Seventy-six samples of blood serum, 125 swab samples and 21 organic samples were collected. The method of agar gel precipitation (AGP) and hemagglutination inhibitory (HI) was adopted in serum detection. The chicken embryo culture was adopted in virus detection. Our results showed: (1) H9 viruses were only found in starlings of Nan'ao, Shantou,in the AI noninfected regions.(2) 31.6% H5 and 23.7% H9 immunoreactive blood serums were detected in Leizhou, Luoding, Haifeng and Shantou. The positive rates of wild birds in inshore area are higher than in other regions. (3) The positive rate of migratory birds is higher than resident birds. Therefore, we concluded that migratory birds would spread AIV in its eruptive period.

2004年初禽流感疫情期间,针对广东省疫点地区开展了野生鸟类禽流感病毒(H5、H7、H9)调查取样工作,共获得血样76份、拭子125份、器官样21份。血清检测采用琼脂扩散(AGP)和血凝抑制试验(HI),病毒检测用鸡胚法鉴定。分析结果:(1)只在非疫点的汕头南澳的八哥上检测到H9病毒;(2)雷州、罗定、海丰及汕头4个地区的血清检测结果中H5和H9阳性率分别为31·6%和23·7%;沿海地区阳性率极显著高于非沿海地区;(3)候鸟的阳性率极显著高于留鸟。因此,该次疫情中候鸟中存在传播禽流感病毒的可能性。

This paper reported the history of avian flu outbreaks in China from 1996 to 2006,directed the characteristics of avian influenza outbreaks in recent years.China is one of the biggest poultry producers in the world and many migratory birds go through China,China faces high risk of pandemic bird flu.The continuing occurrence of sporadic human cases indicates that the virus is continuing to circulate in birds in some parts of the country.In the fighting again avian flu virus,China has developed some possible practice on precautionary and control measure.China enhances international cooperation and scientific involvement in the prevention and control of the avian flu.The State Council and Ministry of Agriculture issued the laws and regulations on avian flu.Wild birds may have played a role in getting domestic fowl and human beings infected with bird flu.Poultry manure is considered to be another key source of the spread routes of H5N1 virus,but the bio-security processing in free range poultry farming and waste products is very poor disposition in China.Epidemic control at grassroots level still needs to be strengthened.

本文综述了从1996年至今禽流感在中国的暴发流行和近年来禽流感的暴发特征。中国是世界最大的家禽生产国,并且大量候鸟迁徙途径中国,中国的禽流感防控形式非常严峻。当前不断出现的人类散发病例说明禽流感病毒仍在部分地区的禽鸟间传播。在与禽流感病毒的斗争中,中国积累了一些有效的防控经验,在禽流感防控的国际合作与相关研究方面也进行了许多积极的努力。国务院和农业部出台了一系列有针对性的法规和方案。在家禽和人类对禽流感病毒的感染途径方面,候鸟可能起了一定作用,人类感染H5N1病毒的主要方式和途径是接触感染病毒的禽类及其分泌物和排泄物,吸入禽类分泌物或排泄物中的病毒颗粒。但中国目前散养家禽的生物安全和废弃物处理状况令人堪忧,基础水平上的防控措施还有待加强。
