A weak positive antibody to Mycoplasma pneumoniae indicates the presence of mycoplasma infections in the body. Mycoplasma may cause upper respiratory tract infections or lower respiratory tract infections, such as pharyngitis, tracheitis, bronchitis or pneumonia, and the appropriate treatment needs to be chosen depending on the site of infection. In case of upper respiratory tract infections, such as pharyngitis or tracheitis, oral treatment with azithromycin or roxithromycin is more effective. In case of bronchitis or pneumonia, the symptoms are often more severe, coughing and coughing up sputum will be more severe and will be accompanied by high fever. Treatment with intravenous macrolide antibiotics, such as erythromycin or azithromycin, is required. If the cough is severe, cough and phlegm relief medications such as Ambroxol Hydrochloride or Ambroterol Oral Solution are also needed. If the fever is high and the body temperature exceeds 38.5°C, you will also need to take ibuprofen suspension to reduce the fever.
