The tonsils help fight infections, but they can become infected themselves. Acute tonsillitis goes along with many throat infections, including strep throat. It is most common in children between the ages of 5 and 10. It usually lasts 4 to 6 days. However, tonsillitis can become a chronic or recurring problem in children or adults.
Acute tonsillitis begins with a mild to severe sore throat.
This is especially important for children. Cases of strep throat require antibiotics. It is very important to finish all antibiotic pills, even if symptoms go away. Many viruses, including mononucleosis, cause tonsillitis. These infections do not require antibiotics.
