    Causes, incidence, and risk factors

    Viralpneumonia is more likely to occur in young children and older adults, because their bodies have a harder time fighting off the virus.

    Viral pneumonia is most often caused by one of several viruses:

    • Adenovirus
    • Influenza
    • Parainfluenza
    • Respiratory syncytial virus

    People who are at risk for more serious viral pneumonia often have a weakened immune system, including:

    • Adult HIV/AIDS patients
    • Babies who are born too early
    • Children with heart and lung problems
    • People receiving chemotherapy for cancer, or other medications that weaken the immune system.
    • Organ transplant recipients
