Mycoplasma infections in children usually take about 1 to 3 weeks, and some even take longer to be clinically cured, depending on the individual. The most common mycoplasma infection in children is Mycoplasma pneumoniae infection, which can present with generalized weakness, sore throat, fever, headache, nausea and vomiting. The specific healing time is related to the child’s own physical condition, the severity of the infection, and so on, and cannot be generalized. Younger patients with weaker bodies may take longer to recover, for example, 3 weeks or even longer, while older children with better resistance may heal faster, perhaps in 1 week or so. The exact time depends on the patient’s own condition, and it is recommended to consult the attending doctor. Children with mycoplasma infection should actively cooperate with the doctor’s treatment to promote the recovery of the disease. The medication should be used in accordance with the doctor’s instructions.
