Having red dots on your body is not a sure sign of AIDS. It is possible to have AIDS with the symptom of red dots on the body, but it is not possible to diagnose AIDS based on this symptom.
There are many causes of red dots, such as contact dermatitis, eczema, Malassezia folliculitis, anaphylactic purpura, idiopathic thrombocytopenic purpura and other diseases.
AIDS is a sexually transmitted disease caused by infection with the human immunodeficiency virus, which causes defects in immune function, leading to a variety of serious opportunistic infections as well as tumors. In the acute stage of HIV infection, a rash may appear as red papules, or red dots, of small diameter, which usually subside within a month. In the AIDS stage, there may be skin damage due to a combination of skin diseases or other illnesses, which may also appear as small red dots on the body. If you suspect HIV infection, you need to go to a regular hospital or the CDC for an HIV antibody test or other tests to make a definitive diagnosis.
There are many diseases that can cause red dots on the body, so simply relying on a symptom is not able to determine whether it is AIDS or not. If you have had high-risk contacts, you need to go to the hospital as soon as possible for examination, clear diagnosis, and treatment as soon as possible.
