Cough symptoms caused by mycoplasma infection are indeed contagious. They can be transmitted through breathing, coughing, and sneezing as these actions release mycoplasma pathogens into the air. These pathogens can then spread to others via airborne droplets. Therefore, it is recommended to isolate the affected individual, wear masks for protection, and, upon diagnosis, promptly choose to administer macrolide antibiotics orally or intravenously to eliminate the mycoplasma pathogens. Additionally, cough suppressants should be used according to the nature of the cough for symptomatic treatment. It is also advised to drink plenty of water, rest adequately, measure body temperature twice daily, avoid spicy and overly greasy foods, and ensure sufficient quality sleep. (Medication should be used under the guidance of a doctor, according to the specific situation.)
