Meningococcus meningitis is an extremely rare disease in early infancy. Root,1 in a careful review of the literature up to 1921, found only six cases of meningococcus meningitis occurring in infants under 2 months of age; two of these infants died during the acute stage of the disease, three died a few months later from sequelae, and the remaining case could not be traced. A seventh case is reported by Cook and Bell2 in a child, aged 17 days, with a fulminating infection of parameningococcus and an extensive petechial rash.
In view of these facts, recovery without sequelae in an infant, aged 7 weeks, following specific serum therapy administered into the cisterna magna, seems of sufficient interest to merit publication.
