Risk factors for tonsillitis include:

  • Young age. Tonsillitis most often occurs in children, but rarely in those younger than age 2. Tonsillitis caused by bacteria is most common in children ages 5 to 15, while viral tonsillitis is more common in younger children.
  • Frequent exposure to germs. School-age children are in close contact with their peers and frequently exposed to viruses or bacteria that can cause tonsillitis.
