[目的]以新型冠状病毒感染为例,介绍基于社区自然人群的急性传染病前瞻性随访研究方法在传染病监测中的探索与应用,为完善传染病监测预警体系提供参考.[方法]采用多阶段按概率比例抽样方法,在上海市16个行政区所有街镇进行抽样,建立基于社区自然人群的急性传染病监测队列,对所有监测对象开展基线调查,并发放新型冠状病毒(简称"新冠病毒")抗原检测试剂.收集2022年12月21日—2023年9月30日前瞻性随访监测对象每周新冠病毒抗原、核酸检测情况,描述监测对象的基线特征以及随访情况.[结果]急性传染病监测队列共纳入12 881名监测对象,男性6 098人(47.3%),女性6 783人(52.7%),基线调查显示35.2%(4 540/12 881)的监测对象既往有新冠病毒感染史.2022年12月21日—2023年9月30日随访期间,该队列人群发病密度为0.61/人·年,女性(0.63/人·年)发病密度高于男性(0.59/人·年).60岁及以上老年人(0.64/人·年)和有基础性疾病者(0.67/人·年)发病密度较高.医务人员的发病密度(0.84/人·年)明显高于其他职业人群.截至2023年9月30日,该队列人群中共有340人发生二次感染,首次感染和再次感染的时间间隔中位数为170 d.[结论]本研究将队列研究方法应用于急性传染病监测中,为社区急性传染病感染率估计和传染病预测预警提供重要的数据支撑,可作为一种新的急性传染病监测方法应用推广.
Establishment and application of a prospective follow-up research method for acute infectious diseases in Shanghai community residents
[Objective]To present the exploration and application of a prospective follow-up research method for acute infectious disease surveillance based on natural community populations,using COVID-19 infection as an example,and to provide a reference for improving the infectious disease surveillance and early warning system.[Methods]A multi-stage probability proportional sampling method was employed to sample residents from all communities of 16 administrative districts in Shanghai,with households as the units.A cohort for acute infectious diseases based on natural community populations was established.The baseline survey was conducted for all cohort subjects,and COVID-19 antigen test kits were distributed.From December 21,2022 to September 30,2023,prospective follow-up monitoring of COVID-19 antigen and nucleic acid was carried out on the study subjects on a weekly basis.The baseline characteristics and follow-up information of the cohort subjects were described.[Results]The cohort for acute infectious diseases included a total of 12 881 subjects,comprising 6 098 males(47.3%)and 6 783 females(52.7%).The baseline survey revealed that 35.2%(4 540/12 881)of the subjects had a history of COVID-19 infection.During the follow-up period from December 21,2022 to September 30,2023,the average incidence density in the cohort was 0.61/person-year,with a higher incidence density in females(0.63/person-year)compared to males(0.59/person-year).Individuals aged 60 and above(0.64/person-year)and those with underlying health conditions(0.67/person-year)had a higher incidence density.Healthcare workers showed a notably higher incidence density(0.84/person-year)than that in other occupational groups.As of September 30,2023,a total of 340 subjects in the cohort experienced secondary infections,with a median interval of 170 days between the first and second infections.[Conclusion]This study applies cohort study method to acute infectious disease surveillance,providing crucial data support for estimating infection rates and forecasting alerts for acute infectious diseases in the community.This method can be promoted and applied as a new approach for acute infectious disease surveillance.
