Sore Throat? Could Be Strep Throat!
The medical term for a "sore throat" is pharyngitis. We owe the word "pharyngitis" to gifts from the Greeks: "pharynx" meaning "the throat" + the suffix"-itis" denoting inflammation. So pharyngitis literally means inflammation of the pharynx.
Like the thigh bone, the pharynx is connected not to the hip bone, but to a remarkable number of other structures including the mouth and nose, the esophagus and larynx, and (via the Eustachian tubes) the ears. That is why sore throats so often involve these other structures.
And that's not all. The pharynx has additional neighbors of renown, namely the nubbins of lymphatic tissue in the back of the pharynx called the "tonsils"and the rings of like tissue higher up in the nasal portion of the pharynx called the "adenoids".
Inflammation of the pharynx causes it to redden and swell which may make breathing and swallowing more difficult. Another features may be an "exudate" or whitish-yellow covering, especially pronounced on the tonsils. The exudate contains dead cells and bacteria or viruses.
The most common cause of pharyngitis is infection by a virus,
especially one of the viruses that can cause the common cold. A
number of viruses including those blamed for influenza
("flu") and infectious mononucleosis ("mono") and
a class of viruses called adenoviruses can cause particularly severe
inflammation of the pharynx.
