Positive mycoplasma in children does not necessarily mean pneumonia. A positive mycoplasma indicates the presence of mycoplasma infection in the body and, depending on the test specimen, suggests a different condition. Therefore, the diagnosis should be based on the laboratory results and combined with other symptoms and tests, and should not be based solely on a positive mycoplasma diagnosis of pneumonia. If the urine culture is positive for mycoplasma, it suggests a urinary tract infection; if the patient’s sputum culture is positive for mycoplasma, it suggests a mycoplasma pulmonary infection or mycoplasma respiratory infection. In case of Mycoplasma pneumoniae infection, there is an incubation period of 2-3 weeks after infection. After the incubation period, rhinitis, pharyngitis and bronchitis will appear, with symptoms such as headache, fever, physical weakness, loss of appetite, and abnormal blood count and chest x-ray examination. If the above symptoms are not present and the ancillary tests are normal, then mycoplasma pneumonia can be ruled out. Mycoplasma pneumonia should be treated promptly after it is identified. The preferred drugs are macrolides such as erythromycin and azithromycin to avoid causing other diseases such as respiratory tract lesions. Also, give your child plenty of water, pay attention to a healthy diet, and keep warm to avoid getting cold.
