Sore throat is a very common disease, but if it is severe, it can affect the normal physiological functions of the body. When sore throat occurs in the organism, it is mostly caused by inflammation, which may be acute smoldering laryngitis, acute tonsillitis, epiglottitis, etc. If the sore throat is obvious unilaterally, it may be caused by peri-tonsillitis or peri-tonsillar abscess. The most common causes of sore throat are viral infections, including the common cold, influenza, and mononucleosis. In young children, coxsackieviruses and herpes viruses are two common viruses; in school-age children, sore throats are primarily caused by bacteria and require antibiotic treatment to prevent serious complications. Environmental irritants such as smoke, air pollution and industrial fumes can also irritate the body’s throat, and are usually accompanied by the following symptoms: severe and sudden sore throat without coughing, sneezing or other cold symptoms: painful or difficult swallowing, fever over 38.3°C, swollen lymph nodes in the neck, white or yellow spots or coatings on the throat and tonsils. Bright red or dark red spots near the throat.
