Nodular itchy rash is not pre-AIDS, but people with AIDS may have nodular itchy rash at the same time.
The cause of nodular itchy rash is unknown, and may be related to emotional factors, mosquito bites, environmental factors, atopic dermatitis, neurodermatitis, eczema, thyroid disease, AIDS, psychosomatic factors, etc., but it does not mean that it is pre-AIDS.
AIDS is a sexually transmitted disease caused by human immunodeficiency virus infection, which gradually causes severe immunodeficiency, leading to a variety of serious opportunistic infections and tumors and death of the disease. Therefore, it is possible for AIDS patients to suffer from nodular itchy rash in combination.
It is not possible to determine whether or not a person has AIDS based on nodular itchy rash, but if there is high-risk contact, it is necessary to go to the hospital for examination in a timely manner.
