Abstract

This article explores disease progression in patients suffering from influenza at Camp Hancock, and includes microscopic images. The authors make the remarkable conclusion that “observation of 1150 soldiers with epidemic influenza pneumonia at Camp Hancock has indicated that the disease as it occurred there differed so essentially in its pathology and course from lobar, broncho- or lobular pneumonia, according to the usual conception of these diseases, that we designated the condition as Acute Bronchitic Emphysema.”
