"The incidence of type 1 diabetes in children increased during the COVID-19 pandemic,1-4 but studies have not discriminated between children with and without infection. We analyzed a large population-based, individual-patient data set that included diagnoses of COVID-19 to determine whether there was a temporal association between COVID-19 and type 1 diabetes in children."

This is an interesting study that reflects some anecdotal stories I've heard from doctors, where there's increased amounts of diagnoses of Type 1 Diabetes in the past few years. While this focuses on children (where viral infections are common triggers for T1DM, I've seen and heard of adults being diagnosed with Type 1 Diabetes, generally after a COVID infection. It calls into question the autoimmune effects of COVID that we might not yet know, especially in regards to diabetes.
