Q

What is tonsilitis?

A

Acute tonsillitis is an acute infection of the parenchyma of the palatine tonsils. This definition does not include tonsillitis as part of infectious mononucleosis, although tonsillitis may occur in isolation or as part of a generalised pharyngitis. The clinical distinction between tonsillitis and pharyngitis is unclear in the literature, and the condition is often referred to simply as “acute sore throat”
