Pharyngitis is inflammation of the pharynx, the part of the throat behind the nose and mouth.
Pharyngitis commonly causes a sore or painful throat and may occur as part of a viral respiratory infection. Some cases are caused by bacteria, including certain strains of Streptococcus.
The cause cannot always be determined from symptoms alone. Treatment depends on the underlying cause, with antibiotics being appropriate only for certain bacterial infections.
QUICK FACT
Most sore throats are not caused by bacteria. Many are associated with viral infections.
COMMONLY CONFUSED WITH
Tonsillitis: Pharyngitis involves inflammation of the pharynx, while tonsillitis specifically involves inflammation of the tonsils. The two can occur together.
