"Tonsillitis is inflammation of the tonsils in the upper part of the throat. Tonsillitis is a type of pharyngitis that typically comes on fast (rapid onset). Symptoms may include sore throat, fever, enlargement of the tonsils, trouble swallowing, and large lymph nodes around the neck. Complications include peritonsillar abscess.
Tonsillitis is most commonly caused by a viral infection and about 5% to 40% of cases are caused by a bacterial infection. When caused by the bacterium group A streptococcus, it is referred to as strep throat. Rarely bacteria such as Neisseria gonorrhoeae, Corynebacterium diphtheriae, or Haemophilus influenzae may be the cause. Typically the infection is spread between people through the air. A scoring system, such as the Centor score, may help separate possible causes. Confirmation may be by a throat swab or rapid strep test." - (en.wikipedia.org 27.12.2020)
