Pharyngitis due to Streptococcus pyogenes

Pharyngitis due to *Streptococcus pyogenes*, also known as group A streptococcal pharyngitis or strep throat, is an acute bacterial infection of the upper respiratory tract affecting the mucosal lining of the pharynx and tonsils The condition is clinically characterized by a sudden onset of sore throat, odynophagia, fever, pharyngeal and tonsillar erythema, tonsillopharyngeal exudates, palatal petechiae, and tender anterior cervical lymphadenopathy, classically in the absence of viral signs such...

While it can occur at any age, it most frequently affects school-aged children and adolescents between 5 and 15 years old

The condition is clinically characterized by a sudden onset of sore throat, odynophagia, fever, pharyngeal and tonsillar erythema, tonsillopharyngeal exudates, palatal petechiae, and tender anterior cervical lymphadenopathy, classically in the absence of viral signs such as cough, coryza, or conjunctivitis Pathophysiologically, the organism colonizes the oropharyngeal mucosa and elicits a pronounced local inflammatory response through diverse virulence factors, with the potential to trigger nons...

Pathophysiologically, the organism colonizes the oropharyngeal mucosa and elicits a pronounced local inflammatory response through diverse virulence factors, with the potential to trigger nonsuppurative sequelae like acute rheumatic fever and poststreptococcal glomerulonephritis if left untreated
