RNA viruses
viruses do harm by:
destroying our cells as their progeny are released
rendering infected cells non-functional
exciting cell-mediated immunity, which destroys otherwise-healthy cells, which happen to be infected by the virus.
causing cell overgrowth, which may be unsightly, a fertile ground of carcinogenesis, or full-blown malignancy
neutralizing antibodies prevent or eliminate viral infection by binding to the viruses themselves
cell-mediated immunity and interferon are also important.
viral inclusions are aggregates of virus proteins, visible by light microscopy

Virus respiratory disorders
URI involve the nose, sinuses, throat, tonsils, and/or middle ear
LRI involve the larynx, trachea, bronchi, alveoli, and/or pleura
in a typical viral interstitial pneumonitis, inflammatory cells fill the alveolar spaces- in fatal chest colds, there is more florid cell damage; death results when the airways are sufficiently damaged to allow fibrin to escape and block air flow and exchange
rhinovirus – the common cold; URI directly, do not cause LRI
coronaviruses – the second most common cause of the cold; do not cause LRI
adenovirus – common colds, chest colds, red eyes, and/or GI upsets; necrosis is typical of the most severe adenovirus pneumonitis, which can be fatal; pathologists notice enlarged, basophilic nuclei without any texture; these denote smudge cells
influenza – primarily an infection of any and all parts of the respiratory tree
