Living with Brazilian hemorrhagic fever

A serious viral illness caused by the Sabia virus, with fever and bleeding signs.

Understanding Brazilian hemorrhagic fever

Brazilian hemorrhagic fever is a viral illness caused by the Sabia virus, believed to have first been identified in Sao Paulo, Brazil.

It causes fever, nausea, vomiting, muscle aches, and tremors, along with bleeding signs. It can occur at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Fever
  • Nausea and vomiting
  • Muscle aches (myalgia)
  • Tremors
  • Tiny red spots in the eyes (conjunctival petechiae)
  • Vomiting blood (hematemesis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
