The study was carried out for reviewing the hypothesis on the relationship between integrated fish farming (IFF) and human influenza A pandemic using study methods of longitudinal epidemiology, ecology and serology. Four rural villages with IFF, non-IFF and non-fish farming, selected from two provinces (Henan and Shandong of PRC) were investigated for the status about human influenza A epidemic and infections with human, duck, swine influenaz A viruses in those communities. The results put forward views on that there is no relation between IFF and the increase of incidence rate, infection rate and antibodies level to human influenza A virus. Duck may play an important role in the increase of infection rate to human influenza A viruses among human communities. Pigs seem not to play obvious role in the increase of infection rate to human influenza A viruses among human communities. Human, duck, swine influenza A viruses may spread among human duck and pigs communities interchangably.
本研究采用纵向流行病学、生态学和血清学研究方法，对综合养鱼（IFF）与甲型人流感大流行之间的关系这一假设进行了回顾。从中国两个省份（河南和山东）选取了四个有综合养鱼、无综合养鱼和无养鱼的农村村庄，调查了这些社区中甲型人流感疫情以及人、鸭、猪甲型流感病毒感染情况。结果表明，综合养鱼与甲型人流感病毒发病率、感染率及抗体水平的增加无关。鸭可能在人类社区中甲型人流感病毒感染率增加方面发挥重要作用。猪在人类社区中甲型人流感病毒感染率增加方面似乎未发挥明显作用。人、鸭、猪甲型流感病毒可能在人、鸭和猪群体之间相互传播。
