Inflammation in the blood is usually an infection in the blood. Common infections include bacterial infections, viral infections, fungal infections and other protozoal infections, but bacterial infections are the most common. Clinically, bacterial infections in the blood are common in immunocompromised patients, such as those who have been using hormones for a long time, those who are severely immunocompromised after chemotherapy for malignant tumors, or those with AIDS. After inflammation of the blood, the patient will show a series of symptoms such as high fever, chills, chills, and petechiae on the skin mucosa. If the patient’s condition is not controlled in time, it may develop into sepsis. If the sepsis is not controlled in time, it will further develop into sepsis. In addition to fever, chills and chills, patients will have abscesses in other organs, causing corresponding symptoms, such as headache, nausea and vomiting when abscesses are formed in the brain, and swelling, pain and difficulty in walking in the joints when abscesses are formed in the joints.
