Eczema and HIV can be distinguished through their characteristic symptoms, transmission routes, and medical tests. If you experience skin problems, it is recommended to observe your condition first and seek medical attention promptly to determine the cause.

1. Different symptoms

Eczema typically manifests as dry, red, itchy skin or small blisters, and may recur, but is mostly limited to the skin surface. Skin problems caused by HIV/AIDS can be more widespread, including systemic symptoms such as persistent fever, swollen lymph nodes, and recurrent infections; skin abnormalities are just one of them.
2. The methods of dissemination are different.
Eczema is a skin inflammation and is not transmitted to others through contact. HIV is mainly transmitted through blood, sexual contact, or mother-to-child transmission; everyday contact such as shaking hands or sharing meals will not lead to infection.
3. The diagnostic method is clear.
Eczema can be diagnosed through a dermatologist's visual examination or allergy testing. HIV requires specific blood tests (such as HIV antibody screening) for confirmation and cannot be inferred from symptoms alone.
If you experience symptoms such as redness, swelling, and itching, first record the pattern of your symptoms and avoid scratching and contact with irritants. If you also have prolonged fever, sudden weight loss, or a history of high-risk behavior, you should go to a reputable hospital as soon as possible for relevant examinations, and a doctor will make a professional judgment based on your specific situation. Daily skin moisturizing and maintaining healthy lifestyle habits can help reduce the occurrence of skin problems.
