Can t1d be triggered by a common cold virus, not just the coxsackie virus? any answers appreciated!

No: T1DM can happen gradually with a buildup of anti-insulin producing cell antibodies for weeks or months when some triggering event brings out symptomatic disease.An illness of any description could be the tipping point, because it triggers stress hormones that raise the blood sugar.There are other ways to kill off insulin production (genetic ,toxic) but a cold will not do the deed.
