At a series of meetings, involving 27 clinicians from 11 countries, case definitions for the diagnosis of Lyme borreliosis in Europe were agreed and are presented here, with appropriate serological criteria, as a diagnostic guide. In a separate study questionnaires directed to clinicians were used to collect information on clinical aspects and risk factors of Lyme borreliosis. ⋯ Cardiac problems were rare. Tick bite was strongly associated with Lyme borreliosis, but the only other significantly associated risk factor was the pastime of gardening.
