Memory B cells then produce the antibodies, hopefully destroying the virus before it can bind to another cell and repeat the HIV life cycle. [155] SARS-CoV-2 and HIV-1 have similarities—notably both are RNA viruses—but there are important differences. As a retrovirus, HIV-1 can insert a copy of its RNA genome into the host's DNA, making ...
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 .
The United States President's Emergency Plan for AIDS Relief (PEPFAR)’s Monitoring Policy Reform tool outlines the progression of policy development related to HIV from problem identification to monitoring and evaluation. The tool supports a relatively simple and uniform monitoring process which can be applied to any policy area.
Structural domains of the HIV-1 integrase. The integration of HIV DNA into the host DNA is a critical step in the HIV life cycle. Understanding the integration process will provide a framework for gaining insight into multiple potential sites of therapeutic intervention for HIV infection and AIDS.
[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.

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 ...
The PRECEDE–PROCEED model is a participatory model for creating successful community health promotion and other public health interventions. It is based on the premise that behavior change is by and large voluntary, and that health programs are more likely to be effective if they are planned and evaluated with the active participation of ...
As HIV-1 PR can only function as a dimer, the mature protease contains two Asp25 amino acids, one from each monomer, that act in conjunction with each other as the catalytic residues. [9] Additionally, HIV protease has two molecular "flaps" which move a distance of up to 7 Å when the enzyme becomes associated with a substrate. [10]
