The most common tick-borne disease in humans is Lyme borreliosis. Extensive field and laboratory tests have revealed that the Borrelia bacterium is present in a larger proportion of ticks than has been shown by earlier studies. Another finding is that migratory birds play an important role in the spreading of ticks and pathogenic agents borne by ticks.

Ticks are to be found in most parts of the world, and more than 900 species have been identified so far. The geographic distribution of these many tick species varies and the most prevalent species in Norway is the forest tick (Ixodes ricinus), which can be the bearer of a number of bacteria and viruses that can infect animals and humans and cause disease.

In recent years, there has been increasing focus on ticks and the diseases a tick bite can cause and there are also indications that ticks are occurring in new areas of the country. This has resulted in an increase in the number of disease cases, both as regards Lyme borreliosis (LB) and other illnesses such as tick-borne encephalitis (TBE).
