Abstract
In addition to causing 12 human deaths and 17 cases of human infection, the 2004 outbreak of H5N1 influenza virus in Thailand resulted in the death or slaughter of 60 million domestic fowl and the disruption of poultry production and trade. After domestic ducks were recognized as silent carriers of H5N1 influenza virus, government teams went into every village to cull flocks in which virus was detected; these team efforts markedly reduced H5N1 infection. Here we examine the pathobiology and epidemiology of H5N1 influenza virus in the 4 systems of duck raising used in Thailand in 2004. No influenza viruses were detected in ducks raised in "closed" houses with high biosecurity. However, H5N1 influenza virus was prevalent among ducks raised in "open" houses, free-ranging (grazing) ducks, and backyard ducks.
摘要
2004年泰国爆发的H5N1流感病毒，除了导致12人死亡和17人感染外，还造成6000万只家禽死亡或被扑杀，扰乱了家禽生产和贸易。在家鸭被认定为H5N1流感病毒的无症状携带者后，政府团队进入每个村庄扑杀检测到病毒的禽群；这些团队的努力显著减少了H5N1感染。在此，我们研究2004年泰国使用的4种养鸭系统中H5N1流感病毒的病理生物学和流行病学。在具有高生物安全性的“封闭”鸭舍中饲养的鸭子未检测到流感病毒。然而，H5N1流感病毒在“开放”鸭舍饲养的鸭子、自由放养（放牧）的鸭子和后院鸭子中普遍存在。
