Karnataka ‘s Department of Health & Family Welfare recently conducted around 2500 tests to check the prevalence of Kyasanur Forest Disease.

About Kyasanur Forest Disease (KFD):

  • It is a tick-born viral hemorrhagic fever, which is also known as Money fever.
  • Origin: It was first identified around 1956 in the Kyasanur Forest area of Shivamogga district, Karnataka.
  • Host: Rats, squirrels, Mice, and Shrews are major hosts.
  • Symptoms: High fever, severe muscle pain, bleeding problems, and low blood pressure.


  • It primarily occurs via the forest tick Haemaphysalis spinigera.
  • It also transmits after a tick bite or contact with an infected animal (a sick or recently dead monkey).
  • No person-to-person transmission has been described.
  • Complications: Severe cases can lead to organ failure, neurological complications, and even death.

Geographical Distribution:

  • Endemic Regions: It is predominantly found in forested areas of southern India, including Karnataka, Kerala, Tamil Nadu, and Maharashtra.
  • Seasonality: Cases typically peak during the dry season, from November to June, coinciding with increased human-tick interactions.


  • Karnataka’s forest department is offering free ‘DEPA Oil’ (a tick repellent) to families who enter the forest areas.
  • Vaccination: A live attenuated vaccine is available for individuals residing in endemic areas, protecting against the disease.


  • Remote Areas: Limited healthcare infrastructure and accessibility in remote forested regions pose challenges for timely diagnosis and treatment.
  • Ecosystem Changes: Deforestation, urbanization, and climate change may influence the distribution and prevalence of KFD.


  • KFD remains a significant public health concern in endemic regions of India, requiring coordinated efforts in surveillance, prevention, and control.
  • Public Awareness: Education and awareness campaigns to inform communities about preventive measures and early recognition of symptoms.
