Maybe its because we are thinking about a spring trip to some destination in South or Central America that an especially good write up on Travelers’ Diarrhea caught our attention.
It includes this about treatment of TD caused by protozoa like cyclospora:
“The most common parasitic cause of TD is Giardia intestinalis, and treatment options include metronidazole, tinidazole, and nitazoxanide (10). Although cryptosporidiosis is usually a self-limited illness in immunocompetent persons, nitazox-anide can be considered as a treatment option. Cyclosporiasis is treated with TMP-SMX. Treatment of amebiasis is with metronidazole or tinidazole, followed by treatment with a luminal agent such as iodoquinol or paromomycin.”
Its the sort of helpful advice that you might want to slip into your permanent travel file.
