【摘要】 用血清学、生态学及纵向流行病学研究方法研究在河南、山东两省选择有、无综合养鱼及不养鱼的4个农村观察点,比较农村人群的发病及人猪鸭群中人猪鸭甲型流感病毒感染情况,以验证综合养鱼导致人类甲型流感流行的假设,结果提出了综合养鱼对人群中甲型流感的发病和感染无关,养鸭对人群中人甲型流感病毒感染率升高起重要作用;而养猪则对感染率似无影响,以及人猪鸭甲型流感病毒可在人猪鸭群间相互传播的见解。更多还原

【Abstract】 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.更多还原
