Pharyngitis is one of the most common disorders in adults and children, with more than 10 million ambulatories visits per year. Group A streptococcus is by far the most common bacterial cause of acute pharyngitis, accounting for approximately 15 to 30 percent of cases in children and 5 to 10 percent of cases in adults. Peak seasons for a sore throat include late winter and early spring. Transmission of typical viral and Group A streptococcus (GAS) pharyngitis occurs mostly by hand contact with nasal discharge, rather than by oral contact.
