Public-private partnership - also called PPP or P3 - is a system in which a government service or private business venture is funded and operated through a partnership of government and one or more private sector organisations or companies, including NGOs. Typically, a PPP is dissatisfied with the impact and or processes of existing HIV/AIDS programs, products and or services available in the community, and has united to initiate actions and provide needed support for themselves (including their families and employees) and others that were impacted by the spectrum comprising HIV and its related diseases; and wants to effect and or influence changes that would visibly improve the health status of PLWAs, PABAs and the community at large. Although other approaches might be available – and indeed might have been used – to pursue HIV/AIDS advocacy nationally and internationally, there still remains an acute dearth of visible concerted effort at the community levels. A typical PPP for sustainable community-based HIV/AIDS advocacy may choose any or several system objectives depending on the peculiarities of its focus community. The sustainability of each community-based PPP’s advocacy projects and activities for HIV/AIDS depends largely on the partnership’s existing facts-backed knowledge-base of the current status of the pandemic and the efforts towards its control within the community. Although by no means compulsive, a quick success-checklist for a PPP engaging in community-based HIV/AIDS advocacy and aiming at sustainability must include factors that will help maximize chances of success, and those that indicate measures/degrees/extent of success achieved by the PPP in its advocacy drive. Sustainable development for every nation or community begins at home with the support of effective domestic policies; while the best way to capitalize upon these effective domestic policies is through building and nurturing local, national, and international public-private partnerships.
