2016-2017年度中国大陆流行性感冒监测分析

摘要

To analyze and summarize the surveillance results and epidemic situation of influenza in mainland China during 2016-2017 surveillance season,we collected ILI monitoring data and influenza outbreak data download from"China Influenza Surveillance Information System"and"Public Health Emergency Information Management System"in mainland China during 2016-2017 surveillance season.The results showed that influenza activity did not appear obvious summer peak in southern provinces,and the autumn and winter flu seasons were earlier than that during last season in both southern and northern prov-inces,while the epidemic peak level was lower than 2015-2016 surveillance season.Throughout the year,influenza predomi-nant viruses throughout the country underwent the alternation of type B,A (H3N2)and H1N1,respectively.The total num-ber of outbreaks of ILI reported in the country was less than that in 2015-2016.According the surveillance,we suggested that all regions continue to attach great importance to recent influenza virus activity,pay attention to the global epidemic situation and that of our country,strengthen the analysis and use of surveillance data,trace the activity levels,mutation and resistance change of influenza virus,carry out the flu outbreak investigation and disposal work timely.%目的 对2016-2017监测年度中国内地流行性感冒的监测结果及流行形势进行分析总结.方法 统计"中国流感监测信息系统"以及"突发公共卫生事件信息管理系统"2016-2017监测年度全年中国内地的 ILI 监测数据以及流感样病例暴发疫情数据.结果 2016-2017监测年度,南方省份流感活动未出现明显的夏季活动高峰,南、北方省份2017年秋冬流感流行季节均早于上一个监测年度,但流行高峰水平低于2015-2016监测年度.整个年度全国的流感流行优势病毒分别就经历了B型、A(H3N2)和甲型 H1N1的交替.全国报告的 ILI暴发疫情总起数低于2015-2016年度,南方片区高于北方片区.结论 各地继续高度重视近期流感病毒活动情况,密切关注全球及我国疫情形势,加强监测数据的分析和利用,跟踪流感病毒的活动水平、变异和耐药性变化,及时开展流感暴发疫情的调查处置和应对工作.
