This is such an important topic, and one that is often not addressed! I saw a blog recently which also discussed the risks and serious impacts of diarrhea and the possibility of using zinc as a treatment. It's too bad that this serious public health concern isn't addressed more often. The organization behind this blog (www.iconsinmed.org) seems to be working to provide consultations for specialty care in areas that don't have the doctors they need - seems like it really could help fix the problem of at least ensuring medical care.
