Living with Kyasanur forest disease

A rare viral infection that starts with fever, headache, and muscle pain and may progress to bleeding problems or nervous system symptoms.

Understanding Kyasanur forest disease

Kyasanur forest disease is a rare infectious disease caused by the Kyasanur forest disease virus.

It starts with fever, headache, and muscle aches (myalgia). It can progress to a hemorrhagic (bleeding) illness. In some cases a second phase follows, with neurological symptoms. It can occur at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these features:

  • Fever
  • Headache
  • Muscle aches (myalgia)
  • Bleeding problems in some people
  • Nervous system symptoms in a second phase for some people

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