Following are true of kyasanur forest disease except –
**Core Concept**
Kyasanur Forest Disease (KFD) is a tick-borne viral hemorrhagic fever endemic to South Asia, primarily in the state of Karnataka, India. It is caused by the Kyasanur Forest Disease virus (KFDV), a member of the Flaviviridae family.
**Why the Correct Answer is Right**
KFDV is primarily transmitted through the bite of infected ticks, particularly the Haemaphysalis spinigera. The virus targets the liver, spleen, and lymph nodes, leading to symptoms such as fever, headache, and hemorrhaging. The disease can be severe and even life-threatening if left untreated.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because KFD is indeed a tick-borne disease, and the primary vector is the Haemaphysalis spinigera tick.
**Option B:** Incorrect because KFDV is a flavivirus, which is a member of the Flaviviridae family, not a member of the Bunyaviridae family.
**Option C:** Incorrect because KFD is not primarily transmitted through contact with infected animals or contaminated food and water.
**Option D:** Incorrect because KFD is not primarily a waterborne disease.
**Clinical Pearl / High-Yield Fact**
KFD is often characterized by the presence of hemorrhagic manifestations, such as petechiae and ecchymoses, which can be a distinguishing feature from other tick-borne illnesses.
