Virus Ecology

This graphic shows the ecological cycle for the Kyasanur Forest Disease virus. The hard tick Haemaphysalis spinagera is both the reservoir and the vector for the virus. Transmission to humans can occur directly through contact with ticks, or through contact with infected monkeys and small animals. Larger animals may become infected, but play a limited role in transmission of disease to humans. No human-to-human transmission has been documented.
