The treatment of pneumonia caused by mycoplasma or chlamydia is mainly the application of macrolide antibiotics such as erythromycin, azithromycin, clarithromycin, etc. in western medicine, and also quinolone antibiotics such as ofloxacin, moxifloxacin, ciprofloxacin, etc., of which children cannot use quinolone antibiotics. Common clinical symptoms of pneumonia caused by Mycoplasma and Chlamydia include moderate to low fever, cough, coughing up white sputum, and in a few cases, high fever, headache, nausea, loss of appetite, and mental atrophy. Chest X-ray or CT may indicate interstitial lung changes, and most routine blood tests show normal white blood cells and no significant C-reactive protein or calcitoninogen. For pneumonia caused by Mycoplasma pneumoniae or Chlamydia infection, in addition to antibiotic treatment, symptomatic nutritional support should be given, which can be combined with Chinese herbal medicine as appropriate.
