The appearance of small red blood spots on the body is not necessarily AIDS, the diagnosis of AIDS should be combined with the AIDS antibody test to determine. The appearance of red blood spots on the body may be allergic purpura, cirrhosis of the liver and other diseases caused by the symptoms. 1. AIDS: Patients who have had a history of high-risk contact with AIDS patients and have red blood spots on their bodies may have symptoms caused by AIDS. In the early stages of AIDS, a rash may appear on the body, but it is usually not specific. The diagnosis of AIDS requires HIV antibody or HIV nucleic acid test, and the diagnosis of AIDS can be confirmed when the result is positive. 2. Anaphylactic purpura: Anaphylactic purpura is an allergic inflammation of small blood vessels throughout the body. Inflammatory reactions occur in the terminal capillaries of the patient, resulting in the appearance of small hemorrhagic spots. As a result, small red blood spots will appear on the body of patients with purpura. 3. Cirrhosis: Cirrhosis refers to the appearance of diffuse fibrosis, pseudolobules, and regenerative nodules in liver tissue. Liver damage leads to a decreased ability to break down estrogen, which leads to the appearance of spider nevi on the skin, which in turn manifests itself on the skin as the appearance of small red blood spots. The appearance of small red blood spots on the body has more causes and is not necessarily a symptom caused by AIDS. Patients with red blood spots should go to the hospital in time and under the guidance of the doctor for regular treatment.
