Prevalencia de dengue y leptospirosis en pacientes febriles en un hospital general de especialidades, México

Among the infectious diseases characterized by a febrile picture are: dengue, leptospirosis, rickettsiosis and salmonellosis, among others. The objective of this study was to identify IgM antibodies against dengue and Leptospira in febrile patientes. The seropositivity for IgM antibodies to dengue was 34%; 26.3% for women and 7.6% for men, without differences significant (p = 0.181). The seropositivity for IgM antibodies to Leptospira was 3.2%, being found only in women. Positive serology for both dengue and Leptospira was 1%. The serovars detected were Pomona and Canicola by the microagglutination technique. It was possible to identify the unsuspected presence of leptospirosis and dengue in atypical months for the latter, an important fact to consider the study of serology in the differential diagnosis of febrile diseases.
