Standard regimen is a 3-day course of a quinolone taken twice daily. The current approach to self-treatment of travellers diarrhea for the typical short-term traveller is to carry three once-daily doses of an antibiotic and to use as many doses as necessary to resolve the illness. If neither high fever nor blood in the stool accompanies the diarrhea, loperamide should be taken in combination with the antibiotic; studies have shown that this combination is more effective than an antibiotic alone and does not prolong illness. Prophylaxis- bismuth subsalicylate- widely used but only -60 effective. For certain individuals e.g., athletes, persons with a repeated history of travelers diarrhea, and persons with chronic diseases, a single daily dose of a quinolone, azithromycin, or rifaximin during travel of 1 months duration is 75-90 efficacious in preventing travellers diarrhea. Causes of travellers diarrhea- Enterotoxigenic E coli is most common cause. Other causes- Enteroaggrative E coli, Salmonella, Shigella, Vibrio, Campylobacter etc.
