Risk and aetiology of diarrhoea at various tourist destinations

Almost two of three tourists developed traveller's diarrhoea during 2-week stays at high risk destinations. Large differences in infection rates betwe en hotels were seen. Patients with milder forms of diarrhoea show a similar chronology to those more severely affected. Although enterotoxigenic Esche richia coli was the most frequent cause, viral pathogens were detected more often than in other studies.
