Regionally the incidence ranged from 58.0 per 100,000 in warminsko-mazurskie voivodeship to 10.8 in lubelskie voivodeship. As observed previously incidence in the urban areas (29.4) was significantly higher then in the rural areas (20.5) and the incidence in men (28.4) exceeded the incidence in women (23.7). The majority of cases occurred in children and adolescents younger then 15 years (mode - 6 years; incidence 406.5. Approximately 2% of cases were hospitalised.
