In the villages, the volunteers provide preventive services such as prenatal checkups and general exams, but most of their time is spent treating a wide range of ailments like malaria, TB, pneumonia, diarrhea, animal or snake bites, and parasites.
The mosquito bites one person or animal with malaria, takes the parasite on board, flies off to another victim, bites and implants the parasite, which proceeds to multiply like crazy, sickening if not killing its victims.
