Tonsils are the two lymph nodes located on each side of the back throat. They function as a defense mechanism, helping to prevent infection from entering the rest of your body. When the tonsils themselves become infected, the condition is called tonsillitis.
Tonsillitis can occur at any age and is a common childhood ailment. It is most often diagnosed in children from preschool age through their mid teens. Symptoms include a sore throat, swollen tonsils, and fever.
This condition can be caused by a variety of common viruses and bacteria and is contagious. If left untreated, tonsillitis caused by strep throat (Streptococcus bacteria) can lead to serious complications.
Tonsillitis is easily diagnosed and treated. Symptoms usually fully resolve within seven to 10 days
