[Epidemiology of group A beta-hemolytic streptococcus in the school population of Pordenone Province].

During the winter months of 1976-1977, our group carried out an epidemiological study in the school population aged 7 years and 10 years respectively, living in the towns of Pasiano (pop. 6,389) and Zoppola (pop. 7,383) in the province of Pordenone. The aim of the study was to determine the incidence of individuals in the school-age group having group A beta haemolitic streptococcus in the pharynx. The results of the study showed a high incidence of children with a positive throat swad. Of the 284 scholars examined, 107 (45.7% of the entire population examined) were carriers, in the pharynx, of group A beta haemolytic streptococcus.
