Abstract
Objectives: 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.
Study design: This is a descriptive epidemiological study.
Methods: 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.
Results: 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).
Conclusions: This study found that the prevalence of influenza was substantially decreased when NPIs were implemented for the containment of COVID-19.
Keywords: COVID-19; Containment; Influenza activity; Non-pharmaceutical interventions.
