Travelers' diarrhea in panamanian tourists in Mexico.
To determine whether residents of developing countries are unlikely to acquire travelers' diarrhea, 64 Panamanians of widely divergent socioeconomic strata were studied during a 15-day tour through Mexico. Twenty-three (36%) tourists experienced 27 episodes of travelers' diarrhea that were caused by seven different pathogens. The most commonly identified etiologic agents were rotavirus (26%), Norwalk virus (15%), and Campylobacter fetus (11%), whereas enterotoxigenic Escherichia coli was not frequently associated with travelers' diarrhea. Acquisition of travelers' diarrhea was correlated directly with high socioeconomic status. Varying levels of immunity to enteropathogens that are endemic in Panama may explain the different isolation rates of pathogens.
