Children’s chlamydial infection cough is divided into causative treatment and symptomatic treatment, such as anti-infective treatment, cough, sputum and so on. 1. Causal treatment: children with mycoplasma infection should be given macrolide antibiotics for anti-infective treatment, such as erythromycin, azithromycin, roxithromycin and so on, in accordance with medical advice. 2. Symptomatic treatment: If the cough is severe, cough suppressants such as cough syrup can be given, and sputum is not easy to cough out, sputum removing drugs such as aminoglutethimide can be given. If the children have serious wheezing, bronchodilators can be used, such as nebulized inhalation of salbutamol. Physical cooling can be used when fever develops, such as warm water wiping the body, hot baths and so on. Children infected with mycoplasma should pay attention to more rest, drink more water, and eat a light diet, which is also conducive to the early recovery of the disease. It is recommended to go to the hospital as soon as possible to find out the cause of the disease and carry out the relevant treatment under the guidance of the doctor. All of the above medications should be used under the guidance of a doctor.
