I would expect it to occur with any virus that causes metabolic disruption. I haven’t seen any statistical analysis on timing of new diagnoses, but many T1s report getting diagnosed around holidays, during which virus transmission (even asymptomatic) naturally spikes.

I’d imagine to even begin to get a feel for it, you’d need a huge sample size and accurate medical record coding to mine for. KP and other large health systems would be the most likely to have the necessary data, but someone would have to see enough value in the research/potential results to actually fund the analysis, even if you had access to the data.
