The basic principles are the same. You need to deal with things like shock and dehydration.

Most volunteers complete their service with nothing more than an occasional bout of diarrhea.
However, they live in remote villages often without electricity. They use pit latrines and rig up outdoor sun heated showers. They boil and filter the water they carry in buckets to their houses. They are constantly exposed to all kinds of parasites and viruses. Yes, they do get diarrhea, URIs, various skin infections, both bacterial and fungal, and lots of anxiety symptoms.
