Seminars in respiratory infections
-
Nosocomial infections with respiratory tract viruses, particularly influenza and respiratory syncytial viruses, account for the majority of serious nosocomial viral disease. Chronically ill, immunocompromised, elderly, and very young hosts are especially vulnerable to potentially life-threatening involvement of the lower respiratory tract. ⋯ Transmission of respiratory syncytial virus, in contrast, seems to require closer contact, with virus passed on hands, fomites, or in large droplets inoculated into the eyes and nose at close range. Strategies for control of nosocomial respiratory syncytial virus are designed to interrupt hand carriage and inoculation of virus onto mucous membranes.
