Nombres alternativos

Virus de la hepatitis D

Definición:

Es un tipo de virus llamado hepatitis D que ocasiona síntomas sólo en personas que también padezcan una infección de hepatitis B.

Causas:

El virus de la hepatitis D (VHD) sólo se encuentra en personas portadoras del virus de la hepatitis B. El VHD puede hacer empeorar una infección por hepatitis B reciente (aguda) o una enfermedad hepática por hepatitis B prolongada (crónica) actual. Este virus puede incluso causar síntomas en personas que portan el virus de la hepatitis B, pero que nunca tuvieron síntomas.

La hepatitis D infecta a alrededor de 15 millones de personas en todo el mundo y se presenta en el 5% de los individuos portadores de hepatitis B.

Los factores de riesgo abarcan:

  • Abusar de drogas intravenosas (IV) o inyectadas
  • Estar infectada durante el embarazo (la madre le puede pasar el virus al bebé)
  • Portar el virus de la hepatitis B
  • Hombres que tienen relaciones homosexuales
  • Recibir muchas transfusiones de sangre
