Here is just a snippet from Epidemiology of Lyme borreliosis in the UK:
“Lyme borreliosis (LB) is the most common vector-borne human infection in England and Wales. As elsewhere in northern Europe, the spirochaetes are transmitted by the hard bodied tick, Ixodes ricinus, commonly known as deer or sheep ticks. Habitats suitable for acquiring Borrelia burgdorferi infection occur in temperate regions of the northern hemisphere, usually in forested woodland or heathland areas which support the life-cycles of ticks and the small mammals and birds that are the reservoir hosts for B. burgdorferi. Several pathogenic genospecies of B. burgdorferi have been identified in Europe, and there is evidence for some variation in the types of clinical presentation caused by these different genospecies.”
