ABSTRACT

La fiebre manchada de las Montañas Rocosas (FMMR) es una enfermedad febril aguda causada por Rickettsia rickettsii, caracterizada por un exantema petequial. A pesar de conocer su etiología y manifestaciones clínicas y de disponer de un tratamiento eficaz, su letalidad aún es elevada. En sus estadios iniciales, la FMMR puede aparentar muchas otras enfermedades infecciosas y dificultar su diagnóstico. El presente trabajo informa dos casos con FMMR que ilustran la importancia de su diagnóstico oportuno y tratamiento adecuado, así como de considerar a la FMMR como diagnóstico diferencial ante un paciente febril con exantema que resida en área endémica.


Rocky Mountain spotted fever (RMSF) is an acute febrile illness caused by infection with Ricketsia Rickettsii, characterized by the presence of petechial rash. Even though the etiology, clinical characteristics and availability of effective antibiotics are known, RMSF related deaths have a prevalence of 4%. In its early stages RMFS can resemble many others infectious conditions and the diagnosis can be difficult. The present paper reports two patients with RMSF; these cases underscore the importance of prompt diagnosis and appropriate antimicrobial therapy, and consider RMSF as a differential diagnosis in any patient who develops fever and rash in an endemic area.
