Pneumonia caused by Mycoplasma pneumoniae infection, known as Mycoplasma pneumonia, refers to acute inflammation of the respiratory tract and lungs caused by Mycoplasma pneumoniae. It is usually accompanied by pharyngitis, bronchitis, and pneumonia. This type of pneumonia accounts for one third of non-infectious pneumonia cases and 10% of pneumonia cases caused by various reasons. Clinically, after infection with Mycoplasma pneumoniae, the symptoms usually appear gradually with a typical incubation period of two to three weeks. Some patients primarily experience fatigue, sore throat, headache, cough, and fever. Others may suffer from diarrhea, loss of appetite, muscle pain, and ear pain. The cough is generally paroxysmal and choking, with little sputum, and the fever can last two to three weeks. Some people may show extrapulmonary manifestations such as dermatitis. In children, complications such as periostitis or otitis media may occur, and there can be swelling of the cervical lymph nodes.
