If symptoms such as headache, fever and sore throat occur, the main consideration is the discomfort caused by upper respiratory tract infection, which can be treated with anti-inflammatory drugs and anti-viral drugs. Anti-inflammatory drugs can be used such as cephalosporin or azithromycin, while antiviral drugs can be treated with drugs such as busulfan or diflucan. If the fever is severe and exceeds 38.5 degrees, consider giving antipyretic drugs. The antipyretic drugs can be Merlin or Tylenol, and the two drugs can be used alternately 4-6 hours apart. If the symptoms of sore throat are more obvious, you may consider applying Throat Sword Spray to spray your throat to reduce the symptoms of sore throat. It is better to do routine blood tests to see if there are abnormalities in lymphocytes, neutrophils and white blood cells. If the elevation of white blood cells is more obvious, it should be considered caused by bacteria; while the elevation of lymphocytes is more obvious, it should be considered caused by viral infection.
