Coughs caused by mycoplasma infections take about 1 to 2 weeks to cure, and may take 3 to 4 weeks or even longer if the symptoms are more severe. Patients with mild mycoplasma infections usually need to be treated for more than a week, and their condition will gradually improve. If the patient’s condition is more severe and treatment is not timely or effective, the effect cough can last for 3~4 weeks or even longer. How long it takes for the cough caused by mycoplasma infection to get better depends on the severity of the infection, the effectiveness of the medication in controlling mycoplasma, and the patient’s own condition, and all factors need to be considered. With medication intervention, the condition will improve more quickly and the cough can gradually diminish. Mycoplasma infections should be treated under the guidance of a doctor and not by self-medication.
