AIDS does not usually cause hair loss. AIDS is an immunodeficiency disease caused by human immunodeficiency virus infection, which is mainly transmitted by blood, sexual contact, mother and child, etc. Once infected, patients may have fever, chronic cough, general malaise, mental instability, diarrhea and other symptoms, and there is currently no clinical data indicating that AIDS can cause hair loss. Hair loss may be related to family genetics, mental stress, endocrine abnormalities, infections and other factors. If the recent hair loss is serious, you can go to the local hospital for early clarification of the cause of the disease and early treatment. If the patient has risky sexual behavior recently, it is recommended that the patient go to the hospital as soon as possible to clarify or exclude the diagnosis as soon as possible to prevent delaying the condition.
