[Clinical and x-ray features of lung lesions in influenza uncomplicated and complicated by pneumonia].

Clinical and X-ray features of pulmonary lesions were studied in 858 inpatients with pneumonia-complicated and uncomplicated influenza. This showed it possible to establish a clinical and X-ray diagnosis of viral pulmonary lesions in the early period of infection. There was a correlation between influenza toxicosis and the magnitude of lung X-ray changes. There were variations in the X-ray pattern of secondary pneumonia in relation to the time of their occurrence.
