We described bronchiolitis epidemics during the 2020-2021 and 2021-2022 seasons in France and their interaction with the COVID outbreak.
Data on family physician (FP) visits, emergency department (ED) visits, hospitalizations for bronchiolitis for children˂2 years, and hospital virological data were analyzed and compared with previous seasons (2015-2020).
The 2020-2021 epidemic arrived very late, and its impact was lower than in previous seasons (2015-2020) (FP visits: -23%, ED visits: -38%, and hospitalizations: -30%). The 2021-2022 epidemic started early (week 40) and lasted for a relatively long time (13 weeks). The impact was higher than in 2015-2020 (FP visits: +13%, ED visits: +34%, hospitalizations: +28%).
Findings from the 2020-2021 epidemic may be linked to the implementation of non-pharmaceutical COVID-19 prevention measures. For 2021-2022, findings may be linked to an "immunity debt" resulting from the lower impact of the previous season.
我们描述了法国 2020-2021 年和 2021-2022 年两个季节的毛细支气管炎流行情况及其与 COVID 爆发的相互作用。
分析了家庭医生（FP）就诊、急诊科（ED）就诊、˂2 岁儿童毛细支气管炎住院和医院病毒学数据，并与前几个季节（2015-2020 年）进行了比较。
2020-2021 年的流行来得很晚，其影响低于前几个季节（2015-2020 年）（FP 就诊：-23%，ED 就诊：-38%，住院：-30%）。2021-2022 年的流行开始得很早（第 40 周），持续时间相对较长（13 周）。其影响高于 2015-2020 年（FP 就诊：+13%，ED 就诊：+34%，住院：+28%）。
2020-2021 年流行的发现可能与非药物 COVID-19 预防措施的实施有关。对于 2021-2022 年，发现可能与前一个季节影响较低导致的“免疫债务”有关。
