The infection is transmitted by a tick bite of Ixodes ricinus . After 3–32 days (on average about a week), a ring-shaped erythema occurs at the site of the bite, which over several weeks, gradually expanding, can reach a diameter of 15–20, and sometimes up to 70 cm. erythematous border with a width of 2-3 mm to 2 cm. In the center of the spot, skin changes are less pronounced. After several weeks or months, the erythematous border disappears.

Despite the disappearance of erythema, in the future, in the absence of treatment, the disease proceeds to the next stage, in which Borrelia penetrate into various organs, the nervous system and heart are affected.
