Welcome to Crohn's Forum, a support group for people with all forms of IBD. While this community is not a substitute for doctor's advice and we cannot treat or diagnose, we find being able to communicate with others who have IBD is invaluable as we navigate our struggles and celebrate our successes. We invite you to join us.
No, auto immune diseases are not passed from person to person like a cold or flu. If it helps any, I've been married to my husband for 15 years as of this coming March. I have IBD and he's never come down with it. An auto immune disease is passed genetically.
