Viral infections of the respiratory tract are responsible for large amounts of time lost from the workplace and significant morbidity and mortality in the very young and the very old. The worldwide pandemic of influenza in 1918 was alone responsible for nearly 30 million deaths in excess of those expected for influenza. Studies have demonstrated the importance of a variety of viruses, including respiratory syncytial virus and parainfluenza virus, which can both cause significant disease in high risk populations. Garibaldi and Prodine1 reported prevalence rates from 3.0% to 4.6% for all viral respiratory infections in long-term care facilities.
