A recent U.S. multicenter study reported outcomes in 64 adults and children with type 1 diabetes, and confirmed or suspected COVID-19. However, only six patients presented with new-onset type 1 diabetes (1).

We report multicenter regional data from North West London (NWL) of new-onset type 1 diabetes and diabetic ketoacidosis (DKA) in children up to the age of 16 years during the peak of the COVID-19 pandemic.

We observed an apparent increase in two units, with 10 cases each (versus typically 2 and 4 cases, respectively, for April/May combined in the previous 5 years).
