摘　　要：目的通过对山东省首次出现的2例人感染H7N9禽流感病例的调查分析,为制定人感染H7N9禽流感预防控制措施提供科学依据。方法 2013年4月采用流行病学、临床检查、血清学监测和Real-time PCR法进行分析和诊断。结果 2例确诊病例均无明显的病、死禽接触史,呈现出家庭聚集性,其他的密切接触者均未发现异常,结合基因序列分析,提示可能存在有限的人传人。结论 2例人感染H7N9病例的感染来源不明确,需加强不明原因肺炎监测和进一步研究有关危险因素。Objective To investigate and analyze the 2 cases infected with human avian influenza H7N9,so as to provide scientific basis for control of human avian influenza infection. Methods Epidemiological investigation,clinical examination serological tests,and real-time PCR were employed for analysis and diagnosis. Results The 2 cases had no history of contact with diseased and dead poultry, presented the family clustering, other close contacts had no abnormalities found, combined with genetic sequence analysis, suggesting there may be limited human-to-human transmission. Conclusion The infection sources of the 2 cases are unknown. The surveillance of pneumonia of unknown causes should be strengthened, and the risk factors associated with avian influenza should be studied in future.
