Mycoplasma infections in children, if treated aggressively, are quickly brought under control and may be cured in about two weeks. However, if the child’s condition is more serious, the treatment time will be relatively longer, and it may take up to three weeks to cure. Mycoplasma infections in children are usually caused by poor body resistance, and early symptomatic treatment is needed after detection. Fever and cough are common after infection, especially dry cough, which can affect the health of the child and early treatment is very important. In addition to anti-infection treatment, attention should also be paid to increasing the child’s resistance to disease, providing more nutrition and encouraging the child to exercise more to promote overall recovery. Mycoplasma infection is a disease that is prone to recurrence and requires comprehensive treatment, as well as good prevention. After resuming daily life, the child should avoid catching a cold to prevent the infection from recurring. Parents should give their children more light and nutritious food to strengthen their resistance.
