2013—2018年江西省南昌市重症肺炎病例流行病学特征分析

Epidemiological characteristics of severe pneumonia cases in Nanchang, Jiangxi, 2013-2018

  • 摘要:
    目的分析江西省南昌市重症肺炎病例的流行病学特征,为重症肺炎病例的临床防治提供依据。
    方法收集2013年4月至2018年3月南昌市重症肺炎病例的呼吸道样本和病例资料,进行病原学和流行病学分析。
    结果来自17家南昌市医疗机构的261例重症肺炎病例,检出流感病毒核酸阳性81例,阳性检出率为31.03%。 其中包括新甲H1(43例)、季H3(13例)、人感染H7N9禽流感(18例)、人感染H10N8禽流感(3例)和乙型流感(4例)。 重症肺炎病例主要集中在冬春季(12月至次年5月),男女性别比为1.69∶1。 病例年龄最小为1月龄,最大为95岁。 21例人感染H7N9/H10N8禽流感病例,病死率33.33%。 90.48%(19/21)的病例通过不明原因肺炎监测发现,年龄中位数为69岁,大部分病例有基础性疾病和明确禽类接触史。
    结论南昌地区重症肺炎病例流感病毒以新甲H1流感病毒流行为主,应及时发现新型流感病毒,坚持监测工作常态化,做好传染病防控工作。

     

    Abstract:
    ObjectiveTo understand the epidemiological characteristics of severe pneumonia cases in Nanchang, Jiangxi province, and provide evidence for clinical prevention and treatment of severe pneumonia cases.
    MethodsThe respiratory samples and clinical data of severe pneumonia cases in Nanchang from April 2013 to March 2018 were collected for the etiological and epidemiological analyses.
    ResultsA total of 261 cases of severe pneumonia from 17 medical institutions in Nanchang were detected, in which 81 were detected to be positive for influenza virus nucleic acid (31.03%), including 43 cases of influenza A (H1N1) pdm09 virus infection, 13 cases of influenza A (H3N2) virus infection, 18 cases of human infection with avian influenza A (H7N9) virus, 3 cases of human infection with avian influenza A (H10N8) virus and 4 cases of influenza B virus infection. The cases mainly occurred in winter and spring (from December to May), and the male to female ratio of the cases was 1.69∶1. The youngest case was 1 month old and the oldest case was 95 years old. Twenty one cases of human infection with H7N9/H10N8 viruses were reported in Nanchang during the 5 years with the case fatality rate of 33.33%. Up to 90.48% of the cases (19/21) were detected through the surveillance for unexplained pneumonia. The median age of the cases was 69 years, most cases had underlying diseases and clear history of poultry contact.
    ConclusionThe major influenza virus causing severe pneumonia was influenza A (H1N1)pdm09 virus in Nanchang. It is necessary to conduct routine surveillance for the timely detection of novel influenza virus and better prevention and control of communicable diseases.
