Fiebre tifoidea - Overview

Nombres alternativos

Fiebre entérica

Definición:

La fiebre tifoidea es una infección que causa diarrea y una erupción cutánea, que se debe más comúnmente a un tipo de bacteria llamada Salmonella typhi (S. typhi).

Causas:

La bacteria que causa la fiebre tifoidea, Salmonella typhi, se propaga a través de alimentos, agua o bebidas contaminadas. Si usted come o bebe algo que esté contaminado, las bacterias ingresan al cuerpo, viajan hacia el intestino y luego hacia al torrente sanguíneo, de donde puede llegar hasta los ganglios linfáticos, la vesícula, el hígado, el bazo y otras partes del cuerpo.

Algunas personas pueden convertirse en portadores de la bacteria Salmonella typhi y continuar expulsando la bacteria en sus heces por años, diseminando la enfermedad.

La fiebre tifoidea es común en países en desarrollo, pero menos de 400 casos se notifican en los Estados Unidos cada año. La mayoría proviene de otros países en donde la fiebre tifoidea es común.
