Incidence of new-onset type 1 diabetes during Covid-19 pandemic: A French nationwide population-based study
Authors' conclusion
In this nationwide study, the incidence of hospitalizations for new-onset T1DM and the incidence of diabetic ketoacidosis at diagnosis was not increased during the Covid-19 pandemic in 2020 and 2021. Our results support the fact that infection with SARS-CoV-2 does not promote the development of T1DM.
