Studies On Streptococcus Group A Infection - Carrier State And Latent Infection Among Children
ACTA PAEDIATRICA SCANDINAVICA(1966)
Abstract
Summary A longitudinal study has been conducted on 114 children in a hospital for primary tuberculosis, in order to determine the incidence of Group A latent streptococcal infection. The subjects were regularly examined for the presence of Group A streptococcus in the throat, the level of streptococcal antibodies in the sera; a daily methodical investigation was also performed in the search of any clinical symptoms of infection. The analysis of the modes of infection shows that several degrees exist between the subject remaining free of any contact with group A streptococcus and that one who presents a clinically acute infection; some children are truly healthy carriers, but more frequently the acquisition of the germ is followed by a rise of serological reactions. This infection may be clinically latent, 01: may show Clinical Symptoms of disease. Children classified as chronic carriers may harbour a single type of streptococcus or two or more types which may or may not be present concurrently within the carrier.
