Pharyngitis can be divided into acute and chronic types, with acute pharyngitis being curable. Acute pharyngitis occurs due to a weakened immune system followed by acute inflammatory infection, such as infections by Staphylococcus aureus, hemolytic streptococcus, or Coxsackie virus, leading to both systemic and local symptoms. Patients may experience sudden high fever, swelling and pain in the throat, and also present with coughing and phlegm among other clinical signs. For treatment, patients firstly need to have a routine blood test. If there is an increase in white blood cells, this indicates a bacterial infection, and patients will need oral antibiotic treatment, for which cephalosporin antibiotics are effective. However, if lymphocytes are elevated, this indicates a viral infection, which does not require any medication. Drinking plenty of water, resting, and maintaining a light diet will generally lead to recovery in about a week. (Please take any medications under the guidance of a professional physician.)
