The Namibian Government is committed to provide services to the citizens of Namibia. Apart from the sector’s responsibility to deliver services by maintaining a healthy and productive workforce, the Government needs to sustain current practices, develop innovative approaches to future challenges, and maintain an institutional memory that sustains the employees and the services rendered to the population of Namibia. HIV and AIDS is one of the factors that impact on the ability of the Public Sector to deliver services. An HIV and AIDS impact assessment has been conducted within the Public Service workforce, including a demographic impact analysis. This analysis provides estimates of HIV prevalence and incidence among the Namibian Public Service workforce and the potential cost impact associated with these estimates.
