Answer

Answer

Chest radiography may assist with the differentiation of viral pneumonias from nonviral pneumonias but are not specific enough alone to confirm the diagnosis. Viral pneumonias tend to display few or no infiltrates on chest radiography, but, when infiltrates are present, they are almost always bilateral, perihilar, symmetric, and interstitial. The appearance of infiltrates in viral pneumonia may be mistaken for pulmonary edema, or vice versa.
