Question
What types of pharyngitis are there? Which one is the most severe? What precautions should be taken?
Answer
Pharyngitis can be divided into two main categories based on the duration of the disease and the nature of pathological changes: acute pharyngitis and chronic pharyngitis. Acute pharyngitis can be further categorized into three types: acute simple, acute edematous, and acute necrotic pharyngitis, with acute simple pharyngitis being the most common. Chronic pharyngitis can be classified into three types: chronic simple, chronic hyperplastic (or hypertrophic), and chronic dry (or atrophic) pharyngitis.
