[Dynamics of streptococcal infections and prevention of post-streptococcal diseases in children's communities of Timişoara].

An analysis was carried out of the dynamics of circulation of the beta-haemolytic streptococcus in pre-school and in school children in the first two years of primary school. The study was performed simultaneously in two groups of children (an experimental and a control group) and allowed, after confrontation of the results obtained, to evaluate correctly the investigations performed, that is the detection of the acute disease and of healthy carriers by bacteriological examinations and early detection of post-streptococcal complications with the aid of serologic examinations (ASLO). The importance is stressed, of living conditions in the family and at school, as well as of individual factors (hereditary, hormonal, immunologic, etc.) in the development of late complications. Thus the measures proposed by the authors are aimed not only at the medical aspects, but also to the social-organizatoric ones.
