HIV Testing Services in Africa: Are They Sustainable?

HIV testing services (HTS) are an essential component of a national response to the HIV epidemic, and in lower and middle income countries, at least 150 million persons are tested annually. HIV testing is necessary to identify persons in need of antiretroviral treatment, which has been documented to be highly effective not only for treatment but also for prevention of HIV transmission to both adults and children. An assessment of the recent literature on sustainability of health and HIV services suggests that organizational performance, flexibility, and integration with other health interventions contribute to sustainability of HIV services and programs.

Expanding HIV testing: back to the future.

The value of HIV testing has grown in parallel with the development of increasingly effective HIV treatment. Evidence for the substantial reductions in transmission when persons receive antiretroviral therapy creates a new impetus to increase testing and early diagnosis. Models of treatment as prevention--dubbed "test and treat"--give reason for optimism that control and elimination of HIV may now be within reach.

"What took you so long?" The impact of PEPFAR on the expansion of HIV testing and counseling services in Africa.

HIV testing and counseling services in Africa began in the early 1990s, with limited availability and coverage. Fears of stigma and discrimination, complex laboratory systems, and lack of available care and treatment services hampered expansion. Use of rapid point-of-care tests, introduction of services to prevent mother-to-child transmission, and increasing provision of antiretroviral drugs were key events in the late 1990s and early 2000s that facilitated the expansion of HIV testing and counseling services.

Lack of knowledge of HIV status a major barrier to HIV prevention, care and treatment efforts in Kenya: results from a nationally representative study.

Background: We analyzed HIV testing rates, prevalence of undiagnosed HIV, and predictors of testing in the Kenya AIDS Indicator Survey (KAIS) 2007.

Methods: KAIS was a nationally representative sero-survey that included demographic and behavioral indicators and testing for HIV, HSV-2, syphilis, and CD4 cell counts in the population aged 15-64 years. We used gender-specific multivariable regression models to identify factors independently associated with HIV testing in sexually active persons.

Evaluation of a U.S. evidence-based parenting intervention in rural Western Kenya: from parents matter! To families matter!

We evaluated Families Matter! Program (FMP), an intervention designed to improve parent-child communication about sexual risk reduction and parenting skills. Parents of 10- to 12-year-olds were recruited in western Kenya. We aimed to assess community acceptability and FMP's effect on parenting practices and effective parent-child communication.

Increasing access to HIV counseling and testing through mobile services in Kenya: strategies, utilization, and cost-effectiveness.

Introduction: This study compares client volume, demographics, testing results, and costs of 3 "mobile" HIV counseling and testing (HCT) approaches with existing "stand-alone" HCT in Kenya. A retrospective cohort of 62,173 individuals receiving HCT between May 2005 and April 2006 was analyzed. Mobile HCT approaches assessed were community-site mobile HCT, semimobile container HCT, and fully mobile truck HCT.

Using mass media campaigns to promote voluntary counseling and HIV-testing services in Kenya.

Background: Kenya, a country with high HIV prevalence, has seen a rapid scale-up of voluntary counseling and HIV-testing (VCT) services from three sites in 2000 to 585 by June 2005. From 2002 onwards, services were promoted by a four-phase professionally designed mass media campaign.

Objective: To assess the impact of a mass media campaign on VCT services.

Couples at risk: HIV-1 concordance and discordance among sexual partners receiving voluntary counseling and testing in Uganda.

Objective: To determine correlates of HIV-1 concordance for couples receiving voluntary HIV counseling and testing.

Design: Cross-sectional study of couples receiving voluntary HIV counseling and testing in Kampala, Uganda.

Methods: An interview and physical examination were conducted for 49 HIV-1-concordant (both partners infected with HIV) and 126 HIV-1-discordant (1 partner infected with HIV and 1 partner HIV negative) couples.

Shadow on the continent: public health and HIV/AIDS in Africa in the 21st century.

Approaches to the prevention and control of the HIV/AIDS epidemic in Africa have been heavily based on early experiences and policies from industrialised countries, where the disease affects specific risk groups. HIV/AIDS has been dealt with differently from other sexually transmitted or lethal infectious diseases, despite being Africa's leading cause of death. In this review, we discuss the evolution of the global response to the epidemic, and the importance of redefining HIV/AIDS in Africa as a public health and infectious disease emergency.
