Overview

Pharyngitis can be caused by infectious microorganisms or non-infectious agents. It is usually caused by viruses but may be caused by bacterial or fungal etiology. Gastroesophageal reflux disease (GERD) or particularly extraesophageal reflux (EER) can also cause acid pharyngitis in adults and children.

Causes

Life Threatening Causes

Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.

Common Causes

Group A beta-hemolytic streptococcus (GABHS) is the most common bacterial cause of pharyngitis.^[1]

+==Overview==
+[[Pharyngitis]] can be caused by infectious [[microorganisms]] or non-infectious agents. It is usually caused by [[viruses]] but may be caused by [[bacterial]] or [[fungal]] etiology. [[Gastroesophageal reflux disease]] (GERD) or particularly [[extraesophageal]] reflux (EER) can also cause acid [[pharyngitis]] in adults and children.
 ==Causes==
-The pharynx is often the first site of infection for many contagious diseases such as the common cold.  This is because viruses and bacteria often settle in this part of the body after a person inhales dust or water vapor containing the microorganism.  Infection can also arise when a person touches their nose or mouth after having touched an object shared with another person with the disease.  The foreign invader reproduces rapidly after settling on the body tissue.
+===Life Threatening Causes===
+[[Life-threatening]] causes include conditions that may result in death or permanent [[disability]] within 24 hours if left [[untreated]].
+*[[Anthrax]]
+*[[Ebola]]
-===Viral sore throats===
+===Common Causes===
-These comprise about 90% of all infectious cases and can be a feature of many different types of viral infections.

-*[[Adenovirus]] - the most common of the viral causes.  Typically the degree of neck [[lymph node]] enlargement is modest and the throat often does not appear red, although is very painful.
+*[[Adenovirus]]
-*[[Orthomyxoviridae]] which cause [[influenza]] - present with rapid onset high temperature, headache and generalised ache. A sore throat may be associated.
+*[[Coxsackie A virus]]
-*[[Infectious mononucleosis]] ("glandular fever") caused by the [[Epstein-Barr virus]].  This may cause significant lymph gland swelling and an[[exudative]] tonsillitis with marked redness and swelling of the throat. The [[heterophile test]] can be used if this is suspected.
+*[[Influenza]]
-*[[Herpes simplex virus]] can cause multiple [[mouth ulcers]].

-:''See also [[Strep throat]]''
-The most common bacterial agent is  [[streptococcus]]. Unlike adenovirus, there tends to be greater generalized symptoms and more signs to find. Typically enlarged and tender lymph glands, with bright red inflamed and swollen throat, the patient may have a high temperature, headache, and aching muscles ([[myalgia]]) and joints ([[arthralgia]]).

-====Diphtheria====
+===Causes in Alphabetical Order===
-[[Diphtheria]] is a potentially life threatening upper respiratory infection caused by ''[[Corynebacterium diphtheriae]]'' which has been largely eradicated in developed nations since the introduction of childhood [[vaccination]] programs, but is still reported in the Third World and increasingly in some areas in Eastern Europe. Antibiotics are effective in the early stages, but recovery is generally slow.
