目的分析福建省2013年1月~2014年6月不明原因肺炎病例监测结果,发现不明原因肺炎病例监测工作中存在的问题,为进一步做好监测工作提供依据。方法系统收集福建省2013年1月~2014年6月所有不明原因肺炎病例监测数据,运用描述性流行病学方法对资料进行流行病学特征分析。结果福建省2013年1月~2014年6月报告不明原因肺炎病例134例,其中明确诊断为人感染H7N9禽流感者20例。病例报告有明显高峰与地区聚集性,与人感染H7N9禽流感疫情高峰和地区分布高度一致。不明原因肺炎发病-诊断的时间间隔为1~34d,中位数为6d,医疗机构诊断符合率为66.42%(89/134),明确病原学诊断率为41.79%(56/134)。结论不明原因肺炎监测对人感染H7N9禽流感病例的发现有重要作用,但是仍然存在很多困难和问题,建议进一步规范不明原因肺炎病例的诊断和报告,同时与流感样病例监测系统相结合,以更好地实现监测目的。
Objective To analyze the surveillance results of pneumonia cases of unexplained pneumonia from January 2013 to June 2014 in Fujian Province and to find out the problems in the surveillance of unexplained pneumonia cases and provide the basis for further monitoring. Methods The surveillance data of all cases of unexplained pneumonia in Fujian province from January 2013 to June 2014 were collected, and the epidemiological characteristics of the data were analyzed by using descriptive epidemiological method. Results From January 2013 to June 2014, Fujian Province reported 134 cases of unexplained pneumonia cases, of which 20 cases were diagnosed as human H7N9 bird flu. Case reports have obvious peaks and regional aggregation, and human infection with H7N9 bird flu outbreak peak and the regional distribution of the same. The incidence of pneumonia was unknown - the time interval between diagnosis and diagnosis was 1 ~ 34 days, and the median was 6 days. The coincidence rate of diagnosis of pneumonia was 66.42% (89/134), and the clear diagnosis rate of pathogen was 41.79% (56/134). Conclusions Pneumonia surveillance plays an important role in the detection of H7N9 bird flu with unknown causes. However, there are still many difficulties and problems. It is recommended to further standardize the diagnosis and reporting of unexplained pneumonia cases and to combine with flu-like case surveillance system to more Good monitoring purposes.
