Possible impact of climate and environmental change on ticks and tick-borne disease in England.

Abstract The survival, density and distribution of ticks are determined by three key elements: microclimate, habitat and host, all of which can be impacted by climate change. The public health risk from ticks is further influenced by human behaviour and the way in which we access and manage the environment where ticks or key tick hosts are found. This expert opinion considers how these factors influence tick-borne disease (TBD) transmission in a changing climate, first by discussing direct effects of climate change on ticks and TBD, and second the indirect effects and environmental changes that make direct comparisons of climate and ticks so challenging.
