Background: Since the Covid-19 pandemic, bronchiolitis outbreaks have been subject to disrupted seasonality, and a major impact on the healthcare system was observed in 2022-23.
Objective: The aim of this article is to describe the characteristics of the 2022-23 bronchiolitis epidemic in the Nouvelle-Aquitaine region, and its impact on the healthcare system.
Method: We described the indicators of dynamics, intensity, severity and impact provided by the bronchiolitis monitoring in place, and compared these with those from previous seasons.
This study estimates the association between emergency department (ED) visits for mental health disorders (MHDs) and the health context of the COVID-19 pandemic in the French region of Nouvelle-Aquitaine. This retrospective study took place between 2018 and 2021 using ED data. We defined the main exposure according to five periods: "Pre-pandemic (reference)", "First lockdown", "Second lockdown", "Third lockdown", and "Pandemic out-of-lockdown.

Objectives: To describe the features of Alpha, Delta and Omicron VOC circulation in the Nouvelle-Aquitaine region, France, between February 2021 and February 2022.
Study Design: Data from the three university hospitals (UH) of Nouvelle-Aquitaine were used to describe regional SARS-CoV-2 circulation (RT-PCR positive rates and identified VOC) as well as its consequences (total number of hospitalizations and admissions in intensive care unit).
Article Synopsis
- The findings indicate a significant increase in seroprevalence from 0.41% in March to 4.93% in May, with about 70% of seropositive individuals having neutralising antibodies.
- The research also estimates an infection fatality rate of 0.84%, which escalates with age, confirming that the lockdown measures were effective in reducing transmission while a majority of the population remained susceptible to the virus.
