Pharyngitis - viral

Definition:

Viral pharyngitis is an inflammation of the pharynx (the part of the throat between the tonsils and the larynx) caused by a virus. It produces a sore throat .

Causes, incidence, and risk factors:

Pharyngitis is most often caused by a viral infection, but can also be caused by a bacterial infection. Viral pharyngitis is the most common cause of a sore throat.

When cultures of the throat do not reveal a bacterial cause for the symptoms, a viral pharyngitis is suspected. These illnesses are extremely common.

Pharyngitis may occur as part of a viral infection that also involves other organ systems, such as the lungs or bowel.
