[目的]分析福建省3例人禽流感病例流行病学特征,为防控提供科学依据。[方法]采用流行病学调查方法,阐述人感染高致病性禽流感病例的流行病学特征、实验室检测、可能的感染来源或暴露因素等。[结果]3例人禽流感病例均发生在冬春季节,早期临床症状无特异性,发病后约1周病情突然急剧加重;虽然均有可疑暴露因素,但无法得到实验室的证实,调查还存在一些局限因素。[结论]人禽流感病例好发于冬春季,发病后1周的临床症状急剧加重,这些特征应引起警惕并可用于鉴别诊断。人禽流感的感染来源、传播途径和影响因素等尚待进一步研究。
[Objective] To analyze the epidemiological characteristics of 3 cases of bird flu in Fujian Province and provide scientific evidence for prevention and control. [Methods] The epidemiological investigation method was used to describe the epidemiological characteristics of human HPAI cases, laboratory tests, possible sources of infection or exposure factors. [Results] All three cases of human bird flu occurred during the winter and spring seasons. The early clinical symptoms were nonspecific. The condition suddenly and aggravately increased about 1 week after the onset of disease. Although there were suspicious exposure factors, they could not be confirmed by the laboratory. There are some limitations. [Conclusion] The cases of human bird flu predominantly occurred in winter and spring. The symptoms of one week after the onset of symptoms were sharply aggravated. These features should be alert and be used for differential diagnosis. The source of infection, the route of transmission and the influencing factors of bird flu have yet to be further studied.
