AIDS can present with the symptom of itchy skin. Due to immune deficiency and immune disorders, AIDS patients are prone to seborrheic dermatitis, urticaria, fungal dermatitis, etc., which may cause itchy skin, but itchy skin is not a specific symptom of AIDS, nor is it a common or typical symptom. However, itchy skin is not specific to AIDS, nor is it a common or typical symptom. It is important to note that these symptoms can occur in other diseases as well as in AIDS, and that the presence or absence of AIDS cannot be determined solely on the basis of the symptoms. There are many factors that can cause itchy skin, such as allergies and infections. If you are worried about HIV infection, you can have your blood tested for HIV antibodies at the hospital 4-6 weeks and 3 months after high-risk behavior to screen for HIV. If there is no high-risk behavior per se and itchy skin occurs, AIDS is not considered first, other skin diseases should be considered first. So it still depends on each individual, if some itchy rash appears, go to the dermatologic venereal disease department as early as possible for early diagnosis and treatment.
