How long does it take for a child to get well from mycoplasma pneumonia is related to the child’s constitution, measures and other factors, and cannot be generalized. Mycoplasma pneumonia in children generally has an incubation period of 2-3 weeks. The early temperature of the child is high, mostly above 39°C, and can last 1-3 weeks. The main manifestation is an irritating cough, the pulmonary signs are not obvious, and a thickening of the hilar shadow is seen on chest radiography. Since mycoplasma pneumonia usually causes damage to the respiratory mucosa, the repair time is relatively longer than that of common pneumonia. If the child is in good health, he or she can usually be cured after 1-2 weeks of standard anti-infective treatment; if the child has poor immunity, it may take 3-4 weeks to recover. The child should cooperate with the pediatrician for standardized anti-mycoplasma treatment, as well as symptomatic treatment of cough and phlegm, and if necessary, nebulization treatment. During the treatment period, pay attention to diet and nutrition, pay attention to protein and vitamin intake to help the disease recover.
