Kyasanur Forest Disease (KFD)

A recent death in Karnataka due to Kyasanur Forest Disease (KFD), also known as monkey fever, has brought renewed attention to this tick-borne viral disease, which can turn fatal if not detected early.

About Kyasanur Forest Disease

Kyasanur Forest Disease is a tick-borne viral haemorrhagic disease that is mainly found in southern India. It was first reported in 1957 in the Kyasanur Forest of Karnataka, and hence the disease derives its name from this region.

The disease is caused by the KFD virus, which belongs to the Flaviviridae family and Flavivirus genus, and is a part of the tick-borne encephalitis complex. It is also called monkey fever because it is associated with deaths in monkeys, which act as important hosts in the disease cycle.

Transmission

Kyasanur Forest Disease is primarily transmitted through the bite of infected hard ticks, especially Hemaphysalis spinigera. Humans may also get infected by handling infected animals, particularly sick or dead monkeys.

The disease does not spread from one person to another, making it a non-contagious infection.

The disease follows a seasonal pattern, usually beginning in October or November, peaking between January and April, and declining by May and June.

Symptoms

The disease begins with a sudden onset of high fever, along with nausea, vomiting, diarrhea, and extreme weakness. In severe cases, patients may develop neurological symptoms and haemorrhagic manifestations.

The fatality rate is around 5 to 10 percent, making early diagnosis and treatment important.

Treatment

There is no specific cure for Kyasanur Forest Disease. Treatment mainly involves supportive care, such as maintaining fluid balance, providing oxygen, managing blood pressure, and treating secondary infections.

With timely medical intervention, many patients recover without complications.

Prevention and Vaccine

A vaccine is available for Kyasanur Forest Disease and is recommended in endemic regions. Vaccination, along with preventive measures such as avoiding tick bites and handling infected animals carefully, plays an important role in controlling the disease.

Conclusion

Kyasanur Forest Disease is a serious but preventable vector-borne disease. Increased awareness, vaccination in endemic areas, and early medical care are essential to reduce mortality and control outbreaks.
