【摘要】：目的通过分析人感染H7N9禽流感疫情流行期间人群筛查结果。探讨和改善新型流感流行期间监测模式。方法比较不同区域、不同级别医疗机构人感染H7N9禽流感人群筛查结果,并与国家级流感监测哨点医院监测结果进行比较。结果各筛查医院在筛查期间共报告流感样病例64 358例,占相关监测科室病人就诊数的1.15%。实际进行人群甲型流感病毒抗原胶体金试剂检测或甲型流感通用引物聚合酶链反应检测的共有20 368例,甲型流感通用阳性率为1.15%;县级及以上筛查医院流感样病例占门急诊就诊总数的比例均高于县以下筛查医院,而在非哨点医院中,高级别医院该比例也高于低级别医院;苏南县级及以上筛查医院甲型通用检测阳性率高于县以下筛查医院,苏中和苏北地区不同级别筛查医院该比例差异无统计学意义(均有P0.05)。结论人群筛查特异性低于哨点监测,当新型流感病毒人间流行后,是否开展人群筛查需综合考虑监测病种的感染谱和流行状态。
[Abstract]:Objective to analyze the screening results of people infected with H7N9 during the epidemic period.To explore and improve the surveillance pattern of new influenza during epidemic period.Methods the screening results of human infected with H7N9 avian influenza in different medical institutions in different regions were compared with those in national influenza surveillance sentinel hospitals.Results during the screening period, 64,358 influenza-like cases were reported in the screening hospitals, accounting for 1.15th of the patients in the relevant monitoring departments.A total of 20,368 cases were tested for influenza A virus antigen colloidal gold reagent or common primer polymerase chain reaction (PCR).The general positive rate of influenza A was 1.15.The proportion of influenza like cases in the outpatient and emergency departments in the screening hospitals at county level and above was higher than that in the screening hospitals below the county level, while in the non-sentinel hospitals, the proportion in the high-level hospitals was also higher than that in the low-grade hospitals.The positive rate of type A in screening hospitals at county level and above in southern Jiangsu was higher than that in screening hospitals below county level, but there was no significant difference between different grade screening hospitals in middle Jiangsu and northern Jiangsu (P 0.05).Conclusion the specificity of population screening is lower than that of sentinel surveillance. Whether or not to carry out population screening should consider comprehensively monitoring the infection spectrum and epidemic status of the new influenza virus.
