From 1977 to 1983, waterfowl migrating along the Atlantic flyway were annually monitored for orthomyxoviruses and paramyxoviruses in an area in central New York State. A total of 168 influenza isolates were obtained from 1,430 waterfowl. Twenty-four combinations of hemagglutinin and neuraminidase subtypes were detected, with as many as 12 found in a single year. One combination, an H5N2 isolate in 1982, was closely related to the virulent chicken virus that appeared in Pennsylvania in 1983. The prevalence of influenza varied greatly among the common waterfowl species: mallards 42%, black ducks 30%, blue-winged teal 11%, wood ducks 2%, and Canada geese 0%. A total of 89 paramyxoviruses were also from these waterfowl. In contrast to findings with influenza virus, the prevalence of paramyxoviruses did not differ significantly among the duck species. Serotype 1 (Newcastle disease virus) was predominant; three other serotypes were also identified. These findings indicated that ducks in the Atlantic flyway continually harbor influenza viruses and paramyxoviruses. The viruses may be a source of infection for other species.
1977年至1983年期间，在纽约州中部的一个地区，每年对沿大西洋飞行路线迁徙的水禽进行正黏病毒和副黏病毒监测。从1430只水禽中总共获得了168株流感病毒分离株。检测到24种血凝素和神经氨酸酶亚型组合，其中一年中发现多达12种。1982年分离出的一种H5N2组合与1983年出现在宾夕法尼亚州的强毒鸡病毒密切相关。流感在常见水禽物种中的流行率差异很大：绿头鸭为42%，黑鸭为30%，蓝翅鸭为11%，林鸳鸯为2%，加拿大鹅为0%。这些水禽中还分离出了89株副黏病毒。与流感病毒的研究结果相反，副黏病毒在鸭类物种中的流行率没有显著差异。1型血清型（新城疫病毒）占主导；还鉴定出了其他三种血清型。这些发现表明，大西洋飞行路线上的鸭子持续携带流感病毒和副黏病毒。这些病毒可能是其他物种的感染源。
