• #22 Bacterial Pharyngitis: Background, Pathophysiology, Epidemiology

  https://emedicine.medscape.com/article/225243-overview

  Pharyngitis, or sore throat, often is caused by infection. Common respiratory viruses account for the vast majority of cases, and these usually are self-limited. Bacteria also are important etiologic agents, and, when identified properly, may be treated with antibacterials, resulting in decreased local symptoms and prevention of serious sequelae. The most common and important bacterial cause of pharyngitis is Streptococcus pyogenes (group A Streptococcus [GAS]). When suspected, bacterial pharyngitis should be confirmed with routine diagnostic tests and treated with various antibiotics. If left untreated, S pyogenes pharyngitis may lead to local and distant complications. To a lesser extent, bacteria other than S pyogenes are known to cause pharyngitis, and these are discussed in Causes. GABHS is spread from person to person through large droplet nuclei. Consequently, close quarters facilitate transmission. In temperate regions, the prevalence of GABHS infection increases in the colder months, presumably because of the tendency of people to congregate indoors. GABHS is a common cause of erysipelas, cellulitis, and necrotizing fasciitis and has been reported as a cause of pneumonia, empyema, toxic shock syndrome, and lymphangitis. The vast majority of these manifestations do not occur in the setting of pharyngitis.
