Convalescence of patients was often greatly prolonged, but ultimate recovery was usually complete. Recurring exacerbations with progression and change of symptoms and lesions occurred in some cases, culminating in a strange and painful disease or state, well designated by the descriptive term "encephalomeningoradiculitis with fibromyositis." The virus was readily demonstrated in the spinal cord2 of patients who died of poliomyelitis during the epidemic but was demonstrated with difficulty in nasopharyngeal washings.3 During a study of the epidemic in 1934 it was found that streptococci isolated from the nasopharynx, urine, stools, spinal fluid and spinal
