Strep Throat

Strep throat is the most common throat infection caused by bacteria.

It is found most often in children between the ages of 5 and 15, although it can occur in younger children and adults. Children younger than 3 years old can get strep infections, but these usually don’t affect the throat.

Strep throat infections usually occur in the late fall, winter, and early spring.
