Abstract

Acute fevers among American servicemen in South Vietnam were studied for a two-year period. The population included 524 patients with an acute fever of unknown origin (acute FUO) of at least four days' duration, and 269 patients who were given a tentative diagnosis of leptospirosis, scrub typhus or an arbovirus infection. Fifty-four per cent of the clinical diagnoses were serologically confirmed and 31 % of the patients with acute FUO were found to be infected with these same agents. Leptospirosis accounted for 20% of these acute fevers; scrub typhus and Japanese encephalitis were also common. Results of viral isolations and serologic testing for enteroviruses, rickettsiae, and influenza virus were of limited usefulness in the remaining patients. A correlation between the etiology of the acute FUO, seasonal incidence and environmental exposure was established. Epidemiologic data and laboratory reinforcement of clinical impressions resulted in a marked improvement in the accuracy of the attending physician's clinical diagnoses as the study progressed.
