Answer

The prognosis is good in the vast majority of patients with viral pneumonia. It is guarded in elderly or immunocompromised patients. Some adenovirus serotypes, especially 2, 3, 7, and 21 have been the cause of serious chronic morbidity after acute respiratory illness, including irreversible atelectasis, bronchiectasis, bronchiolitis obliterans, and unilateral hyperlucent lung. [17] An estimated 14-60% of these children will suffer some degree of permanent lung damage. Many of these patients presented with pharyngitis, tonsillitis, and bronchitis. Adenovirus 14 has a high fatality and morbidity rate in healthy patients. Serious sequelae occurred in those who survived.

Viral pneumonia may leave patients with residual disability from interstitial fibrosis. Infants hospitalized with lower lung infection due to RSV are much more likely to later develop asthma.
