Mycoplasma pneumonia treatment time is usually two weeks, but it should be combined with the patient’s clinical symptoms and related auxiliary examination. The common clinical symptoms of mycoplasma pneumonia are irritating dry cough, sometimes a little white sputum, and no obvious abnormality in the auscultation of the lungs. Blood tests often show that white blood cells are normal or below normal, C-reactive protein and calcitonin are usually normal, and mycoplasma antibody will be more than four times higher in the recent past, which is also a gold standard for diagnosing mycoplasma pneumonia. Chest radiographs or CT of the lungs often show interstitial changes. Often need to use the drug is azithromycin, erythromycin of macrolides, or levofloxacin, moxifloxacin of quinolones, etc., and the full course of treatment is half a month. If the patient’s symptoms improve significantly in a short period of time, it is also possible to consider an appropriate reduction in the cycle of treatment.
