Detailed plan titled “3 by 5” implemented by WHO in 2003 for AIDS means
**Core Concept**
The "3 by 5" initiative was a global health strategy aimed at providing antiretroviral therapy (ART) to 3 million people living with HIV/AIDS in low- and middle-income countries by the end of 2005, thereby increasing access to life-saving HIV treatment.
**Why the Correct Answer is Right**
The "3 by 5" initiative was launched by the World Health Organization (WHO) in 2003, with the goal of accelerating the scale-up of ART in resource-limited settings. This plan focused on improving access to HIV treatment, reducing mortality rates, and mitigating the impact of the HIV/AIDS epidemic in developing countries. The initiative emphasized the importance of community-based care, task-shifting, and the use of generic antiretroviral medications to increase treatment availability.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option does not accurately describe the "3 by 5" initiative, which was specifically focused on increasing access to ART, not prevention or vaccination efforts.
* **Option B:** While the "3 by 5" initiative did involve the use of generic antiretroviral medications, this option does not capture the full scope of the plan.
* **Option D:** This option is not relevant to the "3 by 5" initiative, which was a treatment-focused strategy rather than a research or vaccine development effort.
**Clinical Pearl / High-Yield Fact**
The "3 by 5" initiative demonstrated the feasibility and effectiveness of rapidly scaling up ART in low-resource settings, paving the way for subsequent global health initiatives aimed at increasing access to HIV treatment.
**Correct Answer: C. Increasing access to antiretroviral therapy in low- and middle-income countries.**
