I have both T1D and MS. For MS, one leading idea is that getting exposed to Mono later in life can trigger the disease. There’s solid evidence for this. For T1D, it’s similar - there’s a notion that you’re genetically predisposed to it and certain types of infections during adolescence can cause it to manifest. I’ve had discussions with researchers in the space and apparently certain autoimmune diseases happen less often in “grubbier” parts of the world (their words, not mine) even when the population density is high, and an inference here is that >early exposure< to certain infections might not trigger some of these problematic autoimmune reactions. Side note: these diseases aren’t fun, especially when working in tech. I’m appreciative of those dedicating their lives to researching autoimmune disease.
