Enfermedad del sueño - Overview

Nombres alternativos

Tripanosomiasis africana; Tripanosomosis africana

Definición:

Es una infección con gérmenes transmitidos por ciertas moscas y que ocasiona inflamación del cerebro.

Causas, incidencia y factores de riesgo:

La enfermedad del sueño es provocada por dos gérmenes: Trypanosoma brucei rhodesiense y Trypanosoma brucei gambiense; el primero es el que produce la forma más grave de la enfermedad.

Las moscas llamadas tse-tsé transmiten la infección. Cuando una mosca infectada lo pica a uno, la infección se propaga a través de la sangre.

Entre los factores de riesgo se puede mencionar vivir en partes de África donde se encuentra la enfermedad y ser picado por las moscas tse-tsé. La enfermedad es muy poco común en los Estados Unidos y sólo se encuentra en viajeros que han visitado África o han vivido allí.
