全国性的封城措施于二零二零年春季迅速结束了北方的流感季节。第二波的战略是尽量减少对儿童的限制。儿童传播流感，因此担心流感和COVID-19同时激增。本报告旨在分析芬兰2020-2021年流感季节的流行病学。这项回顾性登记研究的数据来自国家传染病登记处，包括2017年8月至2021年3月的所有实验室确诊流感病例。阳性流感结果按年龄分层，并计算每100 000人的发病率。在2020年8月至2021年3月的流感季中，仅报告了41例甲型和B型流感病例，合计发病率为每10万人年0. 9例。在过去三年中，8月至3月的数字和相应的发病率在2019-2020年为12461（每10万人年282），2018-2019年为15276（每10万人年346），2017-2018年为33659（每10万人年761）。非药物干预措施结合封锁措施，于二零二零年三月中断了芬兰的流感季节。尽管放宽了限制，加上旅行限制和口罩，未能阻止严重急性呼吸系统综合征冠状病毒2型的传播，但这些限制已被证明对季节性流感有效。
The nationwide lockdowns ended influenza seasons rapidly in Northern Hemisphere in Spring 2020. The strategy during the second wave was to minimize the restrictions set for children. Children spread influenza and therefore simultaneous influenza and COVID‐19 surges were feared. The aim of this report is to analyze the epidemiology of influenza season 2020–2021 in Finland. Data for this retrospective register‐based study were gathered from the National Infectious Disease Register, all laboratory‐confirmed influenza cases from August 2017 to March 2021 were included. The positive influenza findings were stratified by age, and incidences per 100 000 persons were calculated. Only 41 influenza A and B cases have been reported in this season from August 2020 to March 2021, which adds up to an incidence of 0.9 per 100 000 person‐years. In the three preceding years, the numbers and corresponding incidences from August to March were 12 461 (282 per 100 000 person‐years) in 2019–2020, 15 276 (346 per 100 000 person‐years) in 2018–2019, and 33 659 (761 per 100 000 person‐years) in 2017–2018. Nonpharmaceutical interventions combined with the lockdown measures interrupted the influenza season in Finland in March 2020. Despite looser restrictions, alongside traveling restrictions and facial masks, failing to prevent the spread of the severe acute respiratory syndrome coronavirus 2 virus, these restrictions have proved to be effective against seasonal influenza.
