Several factors can increase your risk of strep throat infection:

  • Young age. Strep throat occurs most commonly in children between the ages of 5 and 15.
  • Time of year. Although strep throat can occur anytime of the year, it tends to circulate in late fall and early spring. Strep bacteria flourish wherever groups of people are in close contact. That's why the infection spreads easily among family members, in schools and in child care settings.
