Group A<unk>  pharyngitis is most commonly spread through direct person-to-person transmission, typically through saliva or nasal secretions from an infected person. Rarely, contaminated food, especially milk and milk products, can result in outbreaks.The incubation period of group A<unk>  pharyngitis is approximately 2 to 5 days. The pathogenesis of GAS<unk>  involves adhesion of bacteria to pharyngeal mucosa with the help of adhesins on the surface of organism. It then invades the mucosal tissue by producing various proteases and cytolysins causing inflammation, which manifests as the signs and symptoms of pharyngitis.
