Noninfluenzal Viral Infections of the Respiratory Tract

Abstract

THE recent discovery by Rowe et al.¹ and by Hilleman and Werner² of a new group of viruses inhabiting the respiratory tract has given renewed impetus to the study of respiratory infections presumably due to viruses but not caused by any of the previously identified viruses, including those of influenza. Not only are these viruses of importance to the microbiologists but also they appear at present to be causes of at least two clinically recognizable types of respiratory infection formerly considered within the large group of common respiratory diseases of unknown but presumably viral etiology.Many surveys have been made . . .
