Kyasanur Forest Disease (KFD)																									Related Pages
												Kyasanur Forest disease (KFD) is caused by Kyasanur Forest disease virus (KFDV), a member of the virus family *Flaviviridae*. KFDV was identified in 1957 when it was isolated from a sick monkey from the Kyasanur Forest in Karnataka (formerly Mysore) State, India. Since then, between 400-500 humans cases per year have been reported.
Hard ticks (*Hemaphysalis spinigera*) are the reservoir of KFD virus and once infected, remain so for life. Rodents, shrews, and monkeys are common hosts for KFDV after being bitten by an infected tick. KFDV can cause epizootics with high fatality in primates.TransmissionTransmission to humans may occur after a tick bite or contact with an infected animal...Signs and SymptomsSymptoms of KFD may appear suddenly 3-8 days after exposure...Risk of ExposureKFD has historically been limited to the western and central districts of Karnataka State, India...DiagnosisDiagnosis can be made in the early stage of illness by molecular detection by PCR...TreatmentHospitalization and supportive therapy is important for treating KFD...PreventionA vaccine does exist for KFD and is used in endemic areas of India...Outbreak Distribution MapResourcesFactsheet: Kyasanur Forest Disease (KSD) Cdc-pdf[PDF – 2 pages]
