[目的]了解甲型H1N1流感暴发流行规律,为疫情预防控制提供科学依据。[方法]采用暴发流行病学调查研究方法。[结果]5日内出现11例发热样流感病例中有8例为甲型H1N1流感确诊病例,采取隔离治疗措施后7例在1周内转阴,而1例病人前后带毒时间长达20 d,并经使用达菲治疗后一个疗程内转阴。[结论]甲型H1N1流感在人群中的传播速度快而凶猛,隔离治疗措施对控制甲型H1N1流感传播有较好效果,甲型H1N1流感病毒的致病性与季节性流感病毒是否一致,发病后7 d或症状消失后24 h所带毒是否有传染性值得进一步观察研究。
[Objective] To understand the prevalence of influenza A (H1N1) outbreak and provide a scientific basis for the prevention and control of epidemic situation. [Methods] Outbreak epidemiological investigation method was used. [Results] Among the 11 cases of febrile flu in 5 days, 8 cases were diagnosed as Influenza A (H1N1), 7 cases were negative in 1 week after isolation treatment, and 1 case was up to 20 days before and after infection , And after using Tamiflu within a course of treatment negative. [Conclusion] Influenza A (H1N1) virus spread rapidly and fiercely in the population. Isolation treatment has a good effect on controlling the spread of influenza A (H1N1). The pathogenicity of influenza A (H1N1) virus is consistent with that of seasonal influenza virus After 7 days or 24 hours after the disappearance of symptoms of infectious contagious worth further observation.
