Mycoplasma infection fever usually lasts 5-7 days, depending on the severity of the patient’s illness. Mycoplasma respiratory infection usually results in fever on the second day after infection, and is characterized by recurrent fever, cough, sore throat, and malaise, usually in school-age children. The duration of fever due to mycoplasma infection usually lasts about 5-7 days. The duration of fever may be longer if the patient is sicker and has complications such as pleural effusion or encephalitis. In addition, if the patient is in poor health or does not cooperate with treatment, it may take more than 2 weeks for his or her fever to drop to normal. Patients are advised to take standardized treatment under the guidance of a medical professional, take rest, and ensure adequate hydration and nutritional supply.
