Could it be the black plague , It is caused by a virus named yersinia and the flea of the black rat (the comun rat) and it killed half of Europe on the 14 century. Maybe Arakawa used it on FMA.
That's probably what happened. But it was in the 20th century she died and that it was very common.
Either she died from the plague, or she died from a heart attack or cancer.
