[Evaluation of the immune status against poliomyelitis in a group of young immigrants]. / Valutazione dello stato immunitario verso la poliomielite in un campione di giovani immigrati.

ABSTRACT

The immunity state towards poliomyelitis has been evaluated in 506 young immigrants coming from European and extraeuropean countries without immunization history. Polioviruses 1, 2 and 3 antibodies were detected in 97% of the serum samples. 15 subjects did not have detectable antibodies at 12 dilution for one or two polioviruses. Out of these subjects, 6 (coming mostly from East European Region) were negative in the undiluted serum too. On the whole, GMTs for type 1 (43,29) and 2 (41,9) appeared higher than those for type 3 (33,6). Moreover there are differences among the origin countries; in fact, GMTs more elevated for type 1 and 3 (74,6 and 49,6 respectively) have been observed in the subjects coming from the African region, as well in those coming from the American region.
