A functional cure for AIDS is a series of treatments where the HIV virus no longer replicates and affects the body, but the HIV virus is still present in the body. AIDS is an acquired immunodeficiency syndrome caused by the Human Immunodeficiency Virus (HIV), which is an extremely harmful infectious disease. HIV invades the body’s immune system, causing defects in the immune system and triggering a variety of life-threatening opportunistic infections and tumors in patients. Currently, there is a lack of effective drugs to cure HIV in the world, while general treatment, antiviral therapy, and treatment to improve immune function can keep the HIV viral load in the patient’s body at a low level and maintain normal work and life, which is the functional cure of HIV, which is the current standard for clinical cure. HIV patients should go to the hospital for examination in time and be treated under the guidance of the doctor.
