The exact survival time of an AIDS patient without medication is uncertain and depends on the severity of the disease and the presence of underlying medical conditions, ranging from a few months to several decades. AIDS, also known as Acquired Immune Deficiency Syndrome, is caused by the invasion of the HIV virus into the human body, which can attack the body’s immune system leading to a decline in immunity, and is prone to opportunistic infections or malignant tumors that can lead to death. Although there is currently no cure for HIV, it is possible to control HIV replication and progression of the disease through the clinically recognized “cocktail therapy” to prolong the patient’s life cycle. “Cocktail therapy, also known as high-potency antiretroviral therapy (HAART), involves giving patients three or more antiretroviral drugs. The antiretroviral drugs not only inhibit the replication of HIV, but also gradually restore the number of CD4 immune cells in the patient’s body, greatly reducing the probability of AIDS-related complications and death. Therefore, the diagnosis of AIDS does not mean that the patient will not live long, but the patient can prolong the life cycle after following the doctor’s instructions to carry out the relevant treatment.
