title: Viral pneumonia.
abstract: Viral pneumonias are common in infants and young children but rare in adults. Respiratory syncytial virus (RSV) and para-influenza viruses are the most frequent viral pathogens in infants and children. Influenza virus types A and B account for over one half of viral pneumonias in adults. Immunocompromised hosts are susceptible to pneumonias caused by cytomegalovirus (CMV) and other herpesviruses, as well as rubeola and adenovirus. Diagnosis of viral pneumonia depends on appropriate viral cultures and acute and convalescent sera for specific antibodies. Superinfection with bacteria is common in adults. Anti-viral therapy is available for several respiratory viruses. Ribavirin, amantadine/rimantadine, interferon alpha, and acyclovir are antiviral drugs that may be of benefit in treatment and prophylaxis. Prevention of viral pneumonia will depend upon improved viral immunization practices.
