Pharyngitis (pronounced /ˌfærɪnˈdʒaɪtɪs/) is an inflammation of the throat or pharynx.[1] In most cases it is painful and the initial infection can extend for a lengthy time period, and is often referred to as a sore throat.
Like many types of inflammation, pharyngitis can be acute – characterized by a rapid onset and typically a relatively short course – or chronic. The remainder of this article is about the acute form.
It can result in very large tonsils which cause trouble swallowing and breathing. Some cases are accompanied by a cough or fever.
Most acute cases are caused by viral infections (40%–60%), with the remainder caused by bacterial infections, fungal infections, or irritants such as pollutants or chemical substances.[2]
Treatment of viral causes are mainly symptomatic while bacterial or fungal causes may be amenable to antibiotics and anti-fungals respectively.
