Analysis of the environmental and host-related factors affecting the distribution of the tick Dermacentor marginatus

Understanding and responding to the ecological, social and economic conditions that facilitate disease emergence and transmission represents a substantial challenge for epidemiologists and health professionals. In this article we integrate knowledge about the human and the vector population, to provide a context from which to examine the underlying causal factors of D . marginatus -borne diseases emergence in the study area. Within this framework we analyse the biotic and abiotic factors that drive D . marginatus population dynamics and the role of its typical host for dispersal. These investigations suggest that D . marginatus is a tick species prone to spatially overlap its presence with human population presence. Then we consider the public health implications for the residents, when simply carrying out trivial outdoor activities may increase the risk to contact an infected tick.
