1. Pneumonia of a relatively stationary camp population, such as that which occurred among white troops during the period of our investigation, was in considerable part caused by Pneumococcus Types I and II and resembled the pneumonia of civil life.

2. Pneumonia of newly drafted colored troops from southern states during the period of our investigation was caused in great part by pneumococci of those types which occur in the mouths of healthy men, namely, Types IV, III and atypical II.

3. Pneumonia caused by influenza occurred after the epidemic of influenza which we have described. The report states: “With the information available it is not possible to draw a sharp line between (1) the pneumonia of the stable camp population, (2) the pneumonia of the newly drafted southern troops, and (3) the pneumonia following influenza. It is possible that influenza, in greater or less degree, also acts as a predisposing factor in the production of the first and second varieties.”

4. Pneumonia with measles was a frequent and unusually fatal type of the disease. The most important causes of pneumonia during the history of the camp were influenza and measles.
