Migratory pneumonia is a very specific type of pneumonia, relatively speaking in terms of the duration of the disease, which exceeds 1 month but does not exceed 3 months. Pneumonia is characterized by periodic relapses, with progressive exacerbation of the disease with periods of exacerbation. The pathogens that cause pneumonia include common bacteria, viruses, mycoplasma, and chlamydia. Patients prone to migratory pneumonia are mainly special populations, such as those with chronic sinusitis, tonsillitis, malnutrition, long-term use of immunosuppressive drugs, glucocorticoids, and patients with diabetes, as well as organ transplants, are very prone to migratory pneumonia. The clinical manifestations are progressive aggravation of cough and pus, and fluctuation of body temperature, accompanied by wasting and weakness.
