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, <jats:italic>Toxoplasma,<\/jats:italic> 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.<\/jats:p>","DOI":"10.4269\/ajtmh.1973.22.796","type":"journal-article","created":{"date-parts":[[2017,5,10]],"date-time":"2017-05-10T17:40:13Z","timestamp":1494438013000},"page":"796-801","source":"Crossref","is-referenced-by-count":29,"title":["Epidemiology of the acute fevers of unknown origin in South Vietnam: Effect of laboratory support upon clinical diagnosis"],"prefix":"10.4269","volume":"22","author":[{"given":"Steven J.","family":"Berman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George S.","family":"Irving","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William D.","family":"Kundin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Jacques","family":"Gunning","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raymond H.","family":"Watten","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","container-title":["The American Journal of Tropical Medicine and Hygiene"],"original-title":[],"link":[{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/22\/6\/article-p796.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/22\/6\/article-p796.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/22\/6\/article-p796.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,6]],"date-time":"2024-09-06T22:18:14Z","timestamp":1725661094000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/22\/6\/article-p796.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1973,11]]},"references-count":0,"journal-issue":{"issue":"6"},"URL":"https:\/\/doi.org\/10.4269\/ajtmh.1973.22.796","relation":{},"ISSN":["0002-9637"],"issn-type":[{"value":"0002-9637","type":"print"}],"subject":[],"published":{"date-parts":[[1973,11]]}}}
