Abstract
Pulmonary complications associated with influenza, particularly pneumonia, are well recognized and are referred to as influenza (associated) pneumonia. Influenza-associated pneumonia can be classified into several subtypes, including viral pneumonia and superimposed or sequential bacterial pneumonia. Pure influenza viral pneumonia manifests in widespread diffuse lung inflammation, resulting in severe respiratory conditions. Secondary bacterial pneumonia is often seen as a post-influenza complication arising as a consequence of epithelial damage during viral infection. Viral and bacterial pneumonia can co-occur and each can promote the other. Because influenza pneumonia comprises several distinct subtypes with different clinical courses and pathophysiology, it is difficult to uniformly assess pneumonia severity. However, mortality may be slightly higher than expected, based on conventional severity indicators of community-acquired pneumonia.
