## **Core Concept**
The introduction of Antiretroviral Therapy (ART) marks a significant milestone in the management of HIV/AIDS. ART involves the use of antiretroviral drugs to suppress the HIV virus, thereby improving the immune system and reducing the risk of disease progression and transmission.

## **Why the Correct Answer is Right**
Antiretroviral Therapy (ART) was introduced in 1996. This period marked the beginning of the highly active antiretroviral therapy (HAART) era, which significantly changed the treatment landscape for HIV/AIDS. The introduction of ART/HAART was a result of advancements in understanding the HIV life cycle and the development of drugs targeting various stages of viral replication.

## **Why Each Wrong Option is Incorrect**
- **Option A:** 1986 - This is too early for the introduction of ART. Although the first cases of AIDS were reported in the early 1980s, effective antiretroviral treatments were not available until much later.
- **Option B:** 1990 - This is still early for the widespread introduction of ART. While some antiretroviral drugs were available, the combination therapy that characterizes ART today did not become standard until later.
- **Option D:** 2006 - This is too late for the introduction of ART. By 2006, ART had already been in use for over a decade and had become a cornerstone of HIV treatment.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the introduction of ART has significantly improved the life expectancy and quality of life for individuals living with HIV/AIDS. ART is recommended for all individuals with HIV infection, regardless of symptoms or CD4 cell count, to prevent disease progression and reduce the risk of HIV transmission.
