Mycoplasma pneumonia is not a very serious disease and is a common disease in children. Mycoplasma pneumonia starts slowly, with symptoms such as malaise, sore throat, headache, cough, fever, loss of appetite, diarrhea, and muscle pain. The fever usually lasts 2-3 weeks, and the cough may remain after the temperature has normalized. The disease is self-limiting and most can be cured without treatment, and early application of antibiotics can reduce the symptoms and shorten the course of the disease. Generally, Azithromycin is given once a day at 0.5g each time, which is more effective and has fewer adverse reactions, and usually mycoplasma pneumonia will be cured in 2-3 weeks. It is generally recommended to add clothes to the baby and pay attention to the indoor hygiene. If the cough is more serious, it can be treated with cough suppressants.
