Impact de la circulation du SARS-CoV-2 sur les épidémies de bronchiolites chez les enfants de moins de 2 mois : étude comparative rétrospective aux Urgences pédiatriques du Centre Hospitalier Universitaire (CHU) de Bordeaux entre les périodes épidémiques de 2019-2020 et 2020-2021

Abstract : Introduction: acute bronchiolitis in infants is a common respiratory infection resulting in massive use of medical care, especially during the autumn and winter epidemic period. The purpose of this study was to determine whether or not the current COVID-19 pandemic has had an impact on the epidemiological profile of newborns and young infants admitted to the Pediatric Emergency Department for acute bronchiolitis. Material and methods: an observational epidemiological study was carried out in the Pediatric Emergency Department of Bordeaux University Hospital (CHU). Information was collected on patients under two months of age who came for an acute bronchiolitis: - From the 1 st of November 2019 until the 30 th of April 2020 - From the 1 st of November 2020 until the 30 th of April 2021 We then compared the socio-demographic, clinical, biological, and therapeutic data by using multiple statistical tests. Results: in 2020-2021 we observed 3.5 times fewer visits to the Pediatric Emergency Department. The epidemic peak was significantly lower and occured during a completely different time period than usual. Significantly more respiratory viruses were identified in 2020-2021. The Human Respiratory Syncytial Virus (VRS) appears to be the most common agent of infant bronchiolitis, regardless of the period of study. The clinical presentation of infants was comparable between the two periods, without any major contrast between the different criteria studied about severity. Conclusion: this study highlights the impact that the COVID-19 pandemic had on the spread of other respiratory viruses. In effect, there has been a significant decrease of acute bronchiolitis cases in infants under two months old in the Pediatric Emergency Department of Bordeaux University Hospital during the 2020-2021 winter period. Thus, in order to prevent frequent, viral respiratory infections in primary care, it would be necessary to ensure the long-term application of protective sanitary measures
