Sinopsis

Despite advances in diagnosis and treatment, respiratory tract infection continues to be a major cause of morbidity and mortality. Pneumonia is the leading cause of death due to infectious disease (1). More than 6 million cases of bacterial pneumonia occur each year in the United States and the incidence of pneumonia is increasing. The spectrum of organisms known to cause respiratory infections is broad and constantly increasing as new pathogens are identified, and an increasing number of patients have impaired immunity due to disease or medications. In the United States, it has been estimated that there are 1.1 million cases of communityacquired pneumonia requiring hospitalization each year (1). Nosocomial pneumonia is the most important hospital-acquired infection, being associated with the highest mortality rate of nosocomial infections (2). In addition to direct patient care costs, pneumonia is responsible for >50 million days of restricted activity from work and is the sixth leading cause of death in the United States with a mortality rate of 13.4 per 100,000 (3). In the last two decades there has been an increase in not only the prevalence of various infections but also the recognition of several important new viral pathogens. These include hantaviruses, human metapneumovirus, avian influenza A viruses, and coronavirus associated with severe acute respiratory syndrome (SARS)
