The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. [1] There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle.
[citation needed] The continuance of this model is reliant on the prominence of caretakers. In this way, training the next generation of caretakers must include rotation through HIV units and experience with the many stages of HIV care in order to ensure this model of care remains within hospital settings.

Although intervention mapping is presented as a series of steps, the authors see the planning process as iterative rather than linear. [1] Program planners move back and forth between tasks and steps. The process is also cumulative: each step is based on previous steps, and inattention to a particular step may lead to mistakes and inadequate ...
WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease .
HIV is a retrovirus, which comprise a large and diverse family of RNA viruses that make a DNA copy of their RNA genome after infection of a host cell. An essential step in the replication cycle of HIV-1 and other retroviruses is the integration of this viral DNA into the host DNA. The RNA genome of progeny virions and the template for ...
Another area of health system strengthening that PEPFAR has contributed to is its ability to increase the pandemic response to other infectious diseases such as COVID-19. [32] Research by Anand Reddi and colleagues has documented the effectiveness and sustainability of PEPFAR programs by emphasizing the need for integrated approaches to HIV ...
The 3 by 5 Initiative was an initiative of the World Health Organization (WHO) to provide antiretroviral treatment to patients with HIV/AIDS in low- and middle-income countries. [1] The program lasted from December 2003 to December 2005, [2] and the name "3 by 5" refers to the goal of treating 3 million people by 2005. The 3 by 5 Initiative is ...
However, direct killing by HIV alone cannot account for the observed depletion of CD4 + T cells since only 0.01–0.10% of CD4 + T cells in the blood are infected. [ citation needed ] A major cause of CD4 + T cell loss appears to result from their heightened susceptibility to apoptosis when the immune system remains activated.
