It would probably be of interest to find out how many Vietnamese suffer from Crohn's disease. I haven't seen any statistics on that, and not sure where to look. Lots of Vietnamese living in the USA today, almost all refugees from the war (and their descendants). Most South Vietnamese had exposure to Agent Orange (it wasn't used in the North, rather ironic). Primarily those who lived in the countryside were heavily dosed.
Google didn't produce any interesting results, until I used the Vietnamese words for Crohn's disease: Bệnh Crohn
That gave me 53,900 hits, but results are all in Vietnamese. However, you can use Google Translate to make sense out of it. This works best if you use Chrome as your browser, but not absolutely necessary.
