The objective of this study was to evaluate whether the non-pharmaceutical interventions (NPIs) introduced to curb the spread of coronavirus disease 2019 (COVID-19) also interrupted the transmission of influenza.
This is a descriptive epidemiological study.
Data on changes in the number of reported influenza cases, number of influenza-like illness (ILI) visits, ILI percentage and influenza virus positivity were compared between the first 18 weeks of 2020 and the same period of 2019.
The changes in the weekly average number of influenza cases were statistically significant between 2020 and 2019 (-4319 vs -525 per week; P < 0.05). The slopes of regression lines for the number of ILI visits were also statistically significant between 2020 and 2019 (-911 vs -98 per week; P < 0.05).
This study found that the prevalence of influenza was substantially decreased when NPIs were implemented for the containment of COVID-19.
本研究旨在评估为遏制 2019 年冠状病毒病（COVID-19）传播而采取的非药物干预（NPI）是否也中断了流感的传播。
这是一项描述性流行病学研究。
比较了 2020 年的前 18 周和 2019 年同期报告的流感病例数、流感样疾病（ILI）就诊次数、ILI 百分比和流感病毒阳性率的变化。
2020 年和 2019 年每周平均流感病例数的变化具有统计学意义（-4319 与-525 例/周；P<0.05）。2020 年和 2019 年 ILI 就诊次数的回归线斜率也具有统计学意义（-911 与-98 例/周；P<0.05）。
本研究发现，在实施 NPI 以遏制 COVID-19 时，流感的流行率显著降低。
