Streptococcal pharyngitis

A disease of the pharynx, caused by an infection with the gram-positive bacteria Streptococcus pyogenes. This disease is characterised by fever, sore throat, tonsillar exudates, or large cervical lymph nodes. Transmission is commonly by inhalation of infected respiratory secretions, or indirect contact. Confirmation is by identification of Streptococcus pyogenes from a throat swab.
