Acute pharyngitis is caused by viral or bacterial infections following a decrease in the body's immunity and resistance. Patients will experience sudden high fever with body temperature above 38°C, severe throat pain, and may also have symptoms of dry throat, itchy throat, foreign body sensation in the throat, obstruction, breathing difficulties, and hoarseness. Upon examination, congestion and swelling of the soft palate and uvula can be observed, and yellow secretions may be found on the throat wall. In terms of treatment, patients should first go to the hospital for a routine blood test, which generally indicates a bacterial infection. Patients can take oral cephalosporin antibiotics, which are effective. Treatment also involves nebulizer inhalation to alleviate throat congestion and swelling. A light diet, quitting smoking, and abstaining from alcohol can contribute to gradual improvement and recovery within about a week. (Medications should be used under the guidance of a doctor.)
