Ironmouse has been very open about having CVID (Common Variable Immunodeficiency) which is a genetic disorder whose symptoms are not unlike AIDS. The difference is that hers is a genetic disorder and not the result of an STD.
If caught early and treated with high-level medicine people with it can live normal lives (for the most part) but before becoming a vtuber Mousey was poor as shit and had to go for months on end without getting treatment which caused her to develop a lung disease that will eventually kill her.
