HIV-positive means infected with AIDS. If left untreated, the patient’s life may be affected by secondary infections when he or she enters the AIDS stage, and death may occur due to secondary infections and tumors when the patient enters the AIDS stage. The majority of AIDS patients die due to secondary infections or tumors. Therefore, once HIV-positive patients are found and diagnosed with AIDS infection, they should be treated with antiviral drugs as soon as possible. By suppressing the virus in the patient’s body with antiviral drugs, the patient can remain asymptomatic for a long time and the virus in the patient’s body can be maintained at very low or even undetectable levels. Under this condition, the patient’s immune function can be relatively close to that of a normal person, which can prevent various secondary infections and enable the patient to live a relatively long or even close to a normal life expectancy.
