Studies on Tick-Borne Encephalitis and Other Arthropod-Borne Virus Diseases
Abstract
In 1969 and 1970, field studies were continued in order to locate new foci of TBE virus. This was done by virus isolation experiments from ticks collected in woods that had been visited by persons prior to their becoming ill with TBE. The present field studies are done with the aim of finding methods that could lead to the interruption of the virus cycle in nature. This goal could be achieved by measures directed either against the tick vector or the vertebrate reservoir of the virus. One line of investigations deals with the question of whether or not a sufficient reduction of ticks can be achieved with modern insecticides. The other main line of research developed out of the finding that small mammals are essential for the persistence of TBE virus in a focus. First experiments are being conducted in the Taggenbrunn focus in Carinthia with the hope that a reduction of the population density of these vertebrates will be detrimental to the development of nymphs and eventually stop cycling of the virus.
