IN A PREVIOUS study1 observations were made on the course of whooping cough in a group of children, most of whom were under 1 year of age. Streptomycin was administered intranasally, by aerosol method or by intramuscular injection. We had the impression that the course of whooping cough was favorably influenced when streptomycin was given by either the aerosol method or intramuscular injection. Intranasal instillation seemed to have no therapeutic value.
This report concerns the treatment with streptomycin of a second group of infants and a group of older children.
