title: [Beta thalassemia: motivation for screening in Terni].
abstract: There are no definitive data on the frequency of beta-thalassaemia in the Province of Terni; a mass screening programme has not been carried out. Preliminary studies confirm that there is a strong incidence of beta-thalassaemia heterozygotes. A theory can be put forward for the presence of beta-thalassaemia trait, based on the notion of the multicentric genesis of the disorder: the malaria may have been the dominant selective factor.
