N. auteur aut IRD text journalArticle eng text/pdf reformatted digital access The etiology of fever in rural Lao People's Democratic Republic (Laos) has remained obscure until recently owing to the lack of laboratory facilities. We conducted a study to determine the causes of fever among 229 patients without malaria in Savannakhet Province, southern Laos; 52% had evidence of at least one diagnosis (45% with single and 7% with apparent multiple infections). Among patients with only one diagnosis, dengue (30.1%) was the most common, followed by leptospirosis (7.0%), Japanese encephalitis virus infection (3.5%), scrub typhus (2.6%), spotted fever group infection (0.9%), unspecified flavivirus infection (0.9%), and murine typhus (0.4%). We discuss the empirical treatment of fever in relation to these findings. specialized LAOS 050 052 93 3 517-520 2015 0002-9637 https://www.documentation.ird.fr/hor/fdi:010065288 10.4269/ajtmh.14-0772 0002-9637 [F B010065288] https://www.documentation.ird.fr/hor/fdi:010065288 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-08/010065288.pdf IRD - Base Horizon / Pleins textes 2015-11-06 2025-06-13 fdi:010065288 fre
