Mycoplasma pneumoniae is a pathogen without a cell wall between a virus and a bacterium. It is transmitted mainly through the respiratory tract, and healthy people are infected by inhaling the oral and nasal secretions emitted by the patient when coughing or sneezing. The disease is prevalent every 4-6 years, the epidemic season is winter and spring, and the prevalent population is children, which is due to the low autoimmunity of children. In addition, the disease is contagious and contact with patients who may be infected with mycoplasma should be avoided. Patients should wear a mask during the onset of the disease, rest more, drink more water, enhance nutrition, remove intranasal secretions, and keep the respiratory tract open. Avoid spicy and greasy diet.
