Lack of neutralizing antibodies against influenza A viruses in adults during the 2022/2023 winter season – a serological study using retrospective samples collected in Hong Kong

Hong Kong adopted long and stringent non-pharmaceutical interventions during the period of the coronavirus disease (COVID-19) pandemic. A significantly decreased activity of influenza A viruses was also observed since 2020 as recorded by the weekly influenza surveillance (https://www.chp.gov.hk/en/resources/29/304.html), especially after the social distancing and mandatory mask-wearing regulation came into effect [1]. It is expected that influenza virus outbreak will re-emerge after easing of these restrictions in post COVID-19 era.
