G. lamblia is a common protozoan which can be acquired by ingesting unfiltered water. It is seen frequently in people who drink fresh stream water. It is a cause of chronic, nonbloody diarrhea. There is typically a large amount of gas and cramping associated with Giardia infections. RMSF does not typically cause a gastroenteritis. Children with RMSF will commonly have fevers, headaches, and a petechial rash. Rotavirus and Norwalk viruses typically cause acute, self-limited gastroenteritis. The diarrhea is nonbloody, nonmucousy, and typically lasts a few days. (American Academy of Pediatrics, 2003, pp. 283–285) The most appropriate treatment for giardiasis is oral metronidazole. Oral rehydration is an important mainstay in the treatment of diarrhea of any cause but is not a specific treatment for giardiasis. Ciprofloxacin is commonly used for traveler’s diarrhea caused by E. coli.
