The scientific concept of blood poisoning refers to toxemia, i.e., the release of toxins into the blood by a large number of bacteria, which triggers high fever, intoxication or shock and other manifestations of the body. 1. After the onset of toxemia, high fever and sweating, irritability, vomiting and headache, dehydration, acidosis and other symptoms, and in severe cases, shock will occur. 2. In some cases, there will be multiple abscesses, mostly in the lungs, liver, brain, kidneys and other organs. 3. Symptoms of primary diseases causing toxemia may also appear, such as aplastic anemia which may manifest itself as emaciation and swelling, low fever, anemia, and so on. When there are chills and high fever and other discomforts, it is recommended to consult a regular hospital in time. Specific diagnosis and treatment should be carried out under the guidance of physicians.
