摘要

背景2020年的第一波COVID-19大流行在很大程度上是通过限制普通人群的接触来缓解的。方法我们比较了荷兰的两项接触行为研究:在大流行期间和之后进行的 PIENTER Corona 研究(自 2020 年 4 月起每 2-6 个月进行一次)和 PIENTER3 研究(2016-17 年,作为大流行前的基线)。在这两项研究中,参与者(1-85 岁)在调查中报告了前一天所有面对面接触者的人数和年龄组。结果我们发现,2023 年 5 月大流行后,平均每人每天的社区接触人数为 15.4(95% CI:14.3-16.4),比基线(17.8;95% CI:17.0-18.5)低 13%。在所有年龄段中,儿童(5-9 岁)在大流行前后的接触人数最多。主要是 20-59 岁的成年人没有恢复到大流行前的行为,这可能是因为他们更经常在家工作。虽然与大流行前相比,接触者人数有所减少,但如果所有年龄段的人都同样易感,那么新出现的呼吸道病原体对传播潜力的影响是有限的。要为未来的大流行做好准备,这两方面都是必需的。

Contact behaviour before, during and after the COVID-19 pandemic in the Netherlands: evidence from contact surveys, 2016 to 2017 and 2020 to 2023.

BackgroundThe first wave of the COVID-19 pandemic in 2020 was largely mitigated by limiting contacts in the general population. In early 2022, most contact-reducing measures were lifted.AimTo assess whether the population has reverted to pre-pandemic contact behaviour and how this would affect transmission potential of a newly emerging pathogen.MethodsWe compared two studies on contact behaviour in the Netherlands: the PIENTER Corona study, conducted during and after the pandemic (held every 2-6 months from April 2020) and the PIENTER3 study (2016-17, as pre-pandemic baseline). In both, participants (ages 1-85 years) reported number and age group of all face-to-face persons contacted on the previous day in a survey. Transmission potential was examined using the next-generation matrix approach.ResultsWe found an average of 15.4 (95% CI: 14.3-16.4) community contacts per person per day after the pandemic in May 2023, 13% lower than baseline (17.8; 95% CI: 17.0-18.5). Among all ages, children (5-9 years) had the highest number of contacts, both pre- and post-pandemic. Mainly adults aged 20-59 years had not reverted to pre-pandemic behaviours, possibly because they more often work from home. Although the number of contacts is lower compared to the pre-pandemic period, the effect on transmission potential of a newly emerging respiratory pathogen is limited if all age groups were equally susceptible.ConclusionContinuous monitoring of contacts can signal changes in contact patterns and can define a 'new normal' baseline. Both aspects are needed to prepare for a future pandemic.

期刊介绍: Eurosurveillance is a European peer-reviewed journal focusing on the epidemiology, surveillance, prevention, and control of communicable diseases relevant to Europe.It is a weekly online journal, with 50 issues per year published on Thursdays. The journal includes short rapid communications, in-depth research articles, surveillance reports, reviews, and perspective papers. It excels in timely publication of authoritative papers on ongoing outbreaks or other public health events. Under special circumstances when current events need to be urgently communicated to readers for rapid public health action, e-alerts can be released outside of the regular publishing schedule. Additionally, topical compilations and special issues may be provided in PDF format.
