What is sore throat?
Having a sore throat means there is a pain in the back of the mouth.
The throat contains the pharynx, which connects the back of the nose, mouth and swallowing tube (esophagus). The tonsils, which are round lymph glands on either side of the back of the throat, can also cause pain back there.
Sore throat pain may be caused by swelling and inflammation of the mucus membranes in any part of the throat.
When the pharynx is inflamed, it is called pharyngitis.
When the tonsils are inflamed, it is called tonsillitis.
Sometimes a sore throat is referred to as “pharyngotonsillitis,” when both areas are inflamed.
In children most sore throats are caused by a viral infection that often causes cold symptoms in addition to sore throat. Viruses that cause the common cold are often the ones that cause sore throats; Coxsackie virus, mononucleosis and influenza can also cause sore throat symptoms.
Sometimes a sore throat may be caused by a bacterial infection. The most common bacteria involved is Streptococcus pyogenes, also called Group A streptococcus, or Group A strep for short.
When a sore throat is caused by an infection, it can be easily passed from person to person by direct contact with oral/nasal secretions.
