Final answer:
HAART, which stands for Highly Active Antiretroviral Therapy, can slow down HIV virus production, reduce viral load, and strengthen the immune system, leading to improved health for HIV-positive patients.
Step-by-step explanation:
Highly active antiretroviral therapy (HAART) is a treatment for HIV/AIDS which consists of a combination of antiretroviral drugs to maximally suppress the HIV virus and stop the progression of the disease. HAART can slow down the production of new virus, decrease the amount of virus in the body allowing CD4 cell counts to increase, and as a result, lead to a stronger immune system and a healthier patient.
When drugs are used individually, the virus's high mutation rate can lead to rapid resistance, rendering single drugs ineffective over time. However, HAART attacks the virus at different stages of its life cycle, making it more difficult for the virus to develop resistance to multiple drugs simultaneously. The goal of HAART is not only to improve the quality of life but also to decrease the viral load to undetectable levels, though it cannot fully eradicate the virus from the body. Ongoing research aims to find ways to eliminate the virus that remains hidden in immune cells, which could eventually lead to the end of AIDS.
