Cellular Immune Responses Against γ-Inactivated Antigen in the Recovered Cases of Kyasanur Forest Disease.

Kyasanur Forest Disease Virus (KFDV) is a tick-borne flavivirus that causes life-threatening hemorrhagic fever in humans with case fatality rates of 3-5%. Relatively little is known about the mechanism of its pathogenesis or host immune responses to KFDV infection. Here, we investigated KFDV-specific cellular immune responses in the recovered cases of Kyasanur Forest Disease (KFD).

Kinetics of viral RNA, immunoglobulin-M & G antibodies in Kyasanur forest disease.

Background & Objectives: Kyasanur forest disease (KFD) is an infectious disease discovered in Karnataka State of India in 1957; since then, the State has been known to be enzootic for KFD. In the last few years, its presence was observed in the adjoining five States of the Western Ghats of India. The present study was conducted to understand the kinetics of viral RNA, immunoglobulin M (IgM) and IgG antibody in KFD-infected humans for developing a diagnostic algorithm for KFD.

Kyasanur Forest Disease Prevalence in Western Ghats Proven and Confirmed by Recent Outbreak in Maharashtra, India, 2016.

Introduction: Kyasanur forest disease (KFD) outbreak was confirmed in Dodamarg Taluka, Sindhudurga district (Maharashtra) in India during the year 2016. The rise in suspected KFD cases was reported in January 2016, peaked during March, and then declined gradually from April 2016. The outbreak was thoroughly investigated considering different socio-clinical parameters.
