Clinical Features of Infection with Hemadsorption Viruses

IN October, 1957, two new myxoviruses, hemadsorption viruses Types 1 and 2, were isolated from the oropharynx of children.1 Subsequent controlled studies have indicated that these viruses have an etiologic role in pediatric respiratory-tract disease.2 3 4 This paper describes the clinical findings in affected children, who, in general, show a wide spectrum of respiratory-tract illness varying from rhinitis and bronchitis with or without fever through relatively severe croup syndrome or bronchopneumonia.MethodIn this study swabs of the posterior oropharynx of infants and children with respiratory-tract disease and of age-matched controls were tested in several types of tissue culture, including monkey . . .
