Hemorrhage.
Organization with or without infection.
A basis for the interpretation of the respiratory lesions of influenza is offered by the analogous changes in the respiratory tract initiated by the inhalation of poisonous gases.
The respiratory lesions are dependent primarily upon the damage produced by the true etiological agent and the systemic capacity to compensate, and only secondarily upon invasion by the bacterial flora of the mouth and inspired air.
