Acute pharyngitis may cause a fever, but overall, the proportion of cases that develop a fever is relatively small. This is mainly because acute pharyngitis is caused by acute bacterial infections, with a small number of patients possibly experiencing concurrent acute viral infections leading to inflammation. Generally, the common symptoms include sudden onset of sore throat which may affect breathing or swallowing, such as a feeling of obstruction or a foreign body sensation in the throat. Some patients may experience fevers, typically seen in those with more severe inflammatory responses or who have been ill for a longer time without timely treatment. Generally, the fever is mild, though a small number of patients may experience high fever. The main treatment method is anti-infection therapy, and if the body temperature exceeds 38.5°C, it can be combined with antipyretic drugs. (Please consult a professional physician for medication use, and do not medicate blindly.)
