The frequency of symptoms in measles that are referable to the respiratory tract is generally recognized. Little or nothing is known of the roentgenologic changes that occur in the chest during the various stages of the disease. Our purpose in this study, therefore, was to determine by roentgenologic methods the frequency of changes in the lung, the character of these changes and, finally, their progress.
The study is based on the examination of 130 children who were admitted to the Willard Parker Hospital because of measles. Only children admitted during the preeruptive or eruptive stage are included in this series. In a subsequent study, we shall report further data on the roentgenograms of these patients, made from four to eight months after their discharge from the hospital.
Successive roentgenograms of the chest were taken every two or three days during the child's stay in the hospital. In all, 388
