Interesting question. I don't think a contagious component has ever been demonstrated, but of course a lot of the environmental factors would be the same for people living in the same home. I haven't seen any information on how often spouses develop UC, but I have read that with Grave's disease (autoimmune thyroiditis) spouses develop it at significantly higher rates than those whose significant others don't have it.
Makes you wonder, doesn't it? Of course, living with one of "us" might be enough to give a lot of people ulcers. (just kidding, of course)
