This article provides an overview of the seasonal influenza epidemic that occurred in France during the 2022–2023 season. Methods – This summary is based on a descriptive analysis of clinical and virological data from surveillance of influenza-like illnesses in primary care, data from surveillance of influenza and influenza-like illnesses in emergency departments, virological data from hospitals, clinical data on severe influenza cases hospitalized in intensive care units, reports of acute respiratory infection (ARI) episodes in long-term care facilities, including nursing homes, as well as mortality data from electronic death certificates. Results – In mainland France, the 2022–2023 influenza epidemic began in late November 2022 (Week 47 of 2022), peaked in late December, and ended in early April (Week 13 of 2023), for a total duration of 19 weeks. It was characterized by the occurrence of two successive waves. The first wave of the epidemic, primarily linked to the A(H3N2) virus, was of very high intensity and marked by a significant impact on hospitalizations among those under 65, particularly among those aged 15–64. It was followed by a resurgence of the epidemic in late January, of lesser magnitude, primarily due to the B/Victoria virus. This second wave primarily affected those under 15 years of age and had a low impact in terms of severity. Conclusion – The 2022–2023 influenza epidemic, which began early and was exceptionally long, was marked by the occurrence of two successive waves dominated by different influenza viruses (A(H3N2) and B/Victoria, respectively). The first wave of the epidemic occurred concurrently with significant circulation of other respiratory viruses, notably respiratory syncytial virus (RSV) and SARS-CoV-2, and was marked by unusually high severity among young adults. The respective impacts in terms of morbidity and mortality from these various viral epidemics (bronchiolitis, COVID-19, and influenza) thus compounded, primarily in December 2022, placing significant strain on healthcare resources and resulting in high excess mortality. Looking ahead to the 2023–2024 winter season, it is important to emphasize the importance of prevention, particularly through influenza vaccination for at-risk individuals, supplemented by preventive measures to limit the spread of viruses among contacts of confirmed cases.
