Typical age range for Group A strep throat?

• A. 0-4 years
• B. 5-15 years
• C. 16-25 years
• D. 30-50 years

Answer: (B)

GAS pharyngitis most commonly affects school-age children. Around five to fifteen years old, the incidence is highest due to close contact in classrooms and a still-maturing immune system, which makes throat infections more common in this group. While younger children under five can get strep throat and adults can get it too, those groups are less typical compared with the five-to-15-year range. The other age brackets are less representative of the usual pattern, where viral causes are more common in very young children and GAS infections are less frequent as people grow older. So, the typical age range to associate with Group A strep throat is five to fifteen years.
