Last edited: 4/15/2026

Overview

Venezuelan hemorrhagic fever (VHF) is a viral hemorrhagic fever caused by the Guanarito virus, endemic to certain regions of Venezuela, characterized by fever, hemorrhagic manifestations, and multi-organ dysfunction 1.

Diagnosis

  • Clinical presentation includes fever, hemorrhagic symptoms, and signs of organ involvement 1.
  • Laboratory confirmation often involves detecting Guanarito virus-specific IgM antibodies or viral RNA in blood samples 1.
  • Imaging may show nonspecific findings but can help assess organ involvement 1.
  • Management

  • Supportive care is critical, including fluid and electrolyte management, blood product transfusions as needed 1.
  • Ribavirin has been used in some cases, though evidence is limited and primarily based on expert recommendations 1.
  • Management in specialized centers with experience in viral hemorrhagic fevers is advised 1.
  • Special Populations

  • No specific details provided regarding pregnancy, pediatrics, elderly, or comorbidities in managing Venezuelan hemorrhagic fever 12.
  • Key Recommendations

  • Initiate supportive care including fluid resuscitation and monitoring for multi-organ failure (Evidence: Expert opinion) 1.
  • Consider ribavirin therapy under expert supervision, given limited evidence (Evidence: Expert opinion) 1.
  • Transfer patients to specialized centers equipped to handle viral hemorrhagic fevers for optimal care (Evidence: Expert opinion) 1.
