Final answer:
Highly active antiretroviral therapy (HAART) is a combination treatment used to manage HIV. It has significantly improved the outcomes and quality of life for those living with HIV, making it difficult for the virus to develop resistance to the medications.
Step-by-step explanation:
Highly active antiretroviral therapy (HAART) is a medical treatment regimen used for managing and treating the human immunodeficiency virus (HIV). This therapy involves the use of multiple antiretroviral drugs, which work together to reduce the viral load of HIV in the body, maintain immune system functions, and fend off opportunistic infections. By attacking HIV at different stages of its replicative cycle, HAART makes it more difficult for the virus to develop resistance to the drugs.
The most successful application of HAART has been in the treatment of HIV, a retrovirus that can lead to acquired immunodeficiency syndrome (AIDS) if not treated. The introduction of HAART has significantly improved the life expectancy of those living with HIV, allowing for a better quality of life and reducing the transmission of the virus to others.
Therefore, highly active antiretroviral therapy is used to treat B. HIV.
