At CoolTools, an insider's guide to the Peace Corps. An excerpt:
I was one of the most anal volunteers around when it came to hygiene and attempts to ward off diseases that commonly afflicted my fellow PCVs. I washed my hands before every meal, I let my clothes dry for three days before wearing them (to kill any mango-fly eggs), I boiled and filtered my water, I took my malaria prophylaxis religiously, I soaked my veggies in iodine before eating them, and so on. Yet, within my two years, I still managed to get giardiasis, bacterial dysentery, amoebas, malaria, chiggers, turbo worms, fevers, diarrhea, and strange bites, marks, scratches, and rashes that came and went with the winds. I’m not trying to scare you; I only wish to convey to you how how common, bearable, and in many ways unavoidable getting sick in the Peace Corps is. In fact, PCVs often perceive illness as more of an inconvenience and a hot topic of conversation than anything else.
