Type 1 diabetes incidence increased during the <scp>COVID</scp> ‐19 pandemic years 2020–2021 in Czechia: Results from a large population‐based pediatric register

Abstract

The COVID-19 pandemic was associated with a notable upward inflection of the type 1 diabetes incidence curve; the early months of the first lockdown were however hallmarked by a significant dip in new diabetes diagnoses. Long-term observation will show whether the increased incidence originated only from accelerating an advanced preclinical Stage 2 to overt diabetes, or whether the pandemic triggered new cases of islet autoimmunity.
