Outbreak of Kyasanur Forest disease in Thirthahalli, Karnataka, India, 2014

Abstract

Kyasanur Forest disease virus (KFDV) was first identified in 1957, when it was isolated from a sick monkey from the Kyasanur Forest in Karnataka State, India. Since then it has been reported to be enzootic in five districts of Karnataka State, India. Recent reports of human infections have reached an alarming level, in spite of the availability of a vaccine. This disease has also been reported from new areas, such as Tamil Nadu and Kerala State. During January-March 2014, KFDV-positive cases were detected in Thirthahalli taluk, Shimoga District, Karnataka State, India. Here, we report an outbreak of Kyasanur Forest disease occurring in the Kannangi and Konandur area, Thirthahalli taluk in Karnataka State, India, with sporadic cases from eight other areas.
