摘　　要：目的分析海南省2016-2020监测年度流感流行趋势,为科学防控流感提供理论指导。方法对《中国流感监测信息系统》中海南省2016-2020监测年度国家级流感监测哨点医院报告的流感样病例(ILI)及流感监测网络实验室的病原学监测数据进行统计分析。结果 2016-2020监测年度海南省6家国家级流感监测哨点医院共报告流感样病例157 361例,总流感样病例就诊比例(ILI%)为3.05%;0~4岁年龄组在ILI总数中占比最高,占ILI总数的51.01%。全省5家流感网络实验室检测ILI标本25 231例,流感核酸阳性标本3 701例,总核酸阳性率为14.67%;2017-2018年和2019-2020年2个监测年度流感流行呈现双峰特点,夏季流行期集中在4-9月,最高峰值53.64%,冬春季流行期集中在11月~次年3月,最高峰值42.14%,2016-2017年和2018-2019年2个监测年度流感流行没有明显的夏季高峰,冬春季流行期集中在10月-次年3月,最高峰值为54.14%。结论 2016-2020监测年度流感活动强度保持平稳,不同监测年度新甲型H1N1,甲型H3N2,乙型Victoria系4种型别交替流行。应持续加强流感监测工作,密切关注优势流感毒株的变化趋势。Objective To analyze the surveillance results and epidemic situation of influenza in Hainan Province during2016-2020 surveillance season,and to provide scientific evidence for the prevention of influenza.Methods The influenzalike illness(ILI)monitoring data and pathogen surveillance results from"China’s Influenza Surveillance Information System"in Hainan Province during 2016-2020 season were collected and statistically analyzed.Results 157361 cases of ILI were reported by the 6 sentinel hospitals in Hainan province during 2016-2020 season,and the total percentage of influenza like illness(ILI%)was 3.05%.The majority of ILI cases were reported from the 0-5 age group,accounting for 51.01%.A total of25231 cases ILI specimens were detected by the 5 influenza surveillance network laboratories in Hainan province,and the total positive rate was 14.67%.The influenza activity appeared both summer peak and winter-spring peak in the 2017-2018 and 2019-2020 season,concentrating in April-September with supreme peak 53.64%and November-Next year March with42.14%.The 2016-2017 and 2018-2019 season presented only winter-spring peak concentrating in October-next year March with supreme peak 54.14%,while showing no obvious summer peak.The influenza predominant viruses throughout the four-surveillance season underwent the alternation of H1 N1,H3 N2 and type B.Conclusion The influenza epidemic situation was stable during 2016-2020 season and different predominant viruses’types underwent the alternation of A(H1 N1)pdm09,H3 N2,Victoria and Yamagata.We should continue to pay more attention to influenza virus alternation and strengthen the surveillance analysis of influenza virus.
