The term migratory pneumonia, which is mainly proposed for acute and chronic pneumonia, often has a duration of between 1-3 months. The main manifestations are periodic episodes of pneumonia or progressive exacerbations due to poor infection control. The main causes of migratory pneumonia are, in some patients, malnutrition and even rickets. There is also a low autoimmune status, such as long-term hormone use or organ transplantation with immunosuppressive drugs. There are also autoimmune diseases, such as patients with HIV-like diseases.
