Pneumonia is recognized on X-ray studies as infiltrates or consolidations
Finding only suggest diagnosis. Imaging and labs are necessary.
viral- supportive, prevent bacterial.
the typical pneumonia symptoms are less pronounced, with no signs of septicemia, leukocytosis, or abscesses

Can spread if immunocomprimised- granulomatous lesions to virtually any organ, especially the bones, skin, liver, spleen, and CNS (meningitis).
