Candida albicans is not AIDS. Candida albicans invades many parts of the body, causing patients to develop skin candidiasis, mucous membrane candidiasis, and visceral and central nervous system candidiasis. AIDS is an infectious disease caused by the HIV virus, which is mainly transmitted by people infected with HIV or AIDS patients. HIV is mainly found in the blood, semen, vaginal secretions, cerebrospinal fluid, breast milk and other bodily fluids of the patient or infected person, and the infection is spread through sexual contact, blood, and vertical transmission from mother to child.
