Introduction: HIV infection is still a global public health problem. More than 75% of HIV-infected people are in Africa, and up to 54% are unaware of their HIV status, limiting access to antiretroviral treatment., Context and Purpose of the Study: This review aimed to determine whether HIV self-testing (HIVST) increases the uptake of testing, the yield of new HIV-positive diagnoses, and the linkage to antiretroviral treatment, and social harms among adults in Africa., Methods: PubMed, The Cochrane Central Register of Controlled Trials (CENTRAL), Pan African Clinical Trials Registry, The Cochrane Database of Systematic Reviews (CDSR), Databases of Abstracts of Reviews of Effectiveness (DARE), Social Sciences Citation Index, Web of Science and African Index Medicus databases were searched from 1998 to 2019 (updated in December 2019). Eligible trials employed randomized controlled trials (RCTs), before/after studies, and interrupted time series design comparing HIVST to standard HIV testing services or comparing different approaches to HIVST among adults living in Africa were systematically sought., Results: After searching 2,617 citations eleven trials were identified including 59,119 participants from four (4) African countries. Meta-analysis of seven trials showed a significant increase in the uptake of HIVST compared to standard HIV testing services: Both fixed-effects (Rate Ratio (RR) = 2.64, 95% CI: 2.51 to 2.79), and random-effects (RR) = 3.10, 95% CI: 1.80 to 5.37, and a significant increase in the uptake of couples' HIVST (RR = 2.50, 95% CI: 2.29 to 2.73 in fixed-effects models; and RR = 2.64, 95% CI: 2.01 to 3.49 in random-effects model). A decrease in linkage to care and ART was observed in HIVST compared to standard HIV testing services (RR = 0.88, 95% CI: 0.88 to 0.95 in fixed-effects models; and RR = 0.78, 95% CI: 0. 56 to 1.08 in random-effects models). Six RCTs measured social harms, with a total of ten reported cases related to HIVST. One RCT comparing two approaches to HIVST showed that offering home-based HIVST with optional home-initiation of antiretroviral treatment increased the reporting of a positive HIV test result (RR: 1.86; 95% CI: 1.16 to 2.98), and linkage to antiretroviral treatment (RR: 2.94; 95% CI: 2.10 to 4.12), compared with facility-based linkage to antiretroviral treatment., Conclusions: HIVST has the potential to increase the uptake of HIV testing compared to standard HIV testing services. Offering HIVST with optional home initiation of HIV care compared to HIVST with facility-based HIV care increases HIV positivity and linkage to antiretroviral treatment. Reported incidences of intimate partner violence related to HIVST were rare. Future research should focus on the potential of HIVST to reach first-time testers, the effect of using different approaches to HIVST, and strategies for linkage to HIV services., Systematic Review Registration: This systematic review was prospectively registered on the Prospero International Prospective Register of Systematic Review (CRD42015023935)., Competing Interests: The authors have declared that no competing interests exist.

Background: More than 40% of adults in Sub-Saharan Africa are unaware of their HIV status. HIV self-testing (HIVST) is a novel approach with a potential to increase uptake of HIV testing and linkage to care for people who test HIV positive. We explored HIV stakeholder's perceptions about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing of adult users in Africa., Methods: This systematic review of qualitative evidence included articles on qualitative studies published or made available between January 1998 to February 2018 on perspectives of key stakeholders, including HIV policymakers, HIV experts, health care providers, and adult men and women (18 years and above) about factors that enable or deter the uptake of HIV self-testing and experiences of self-testing among adult users. We searched CINAHL, MEDLINE in Pubmed, EMBASE, AJOL, PsycINFO, Social Science Citation Index (SSCI), and Web of Science for articles in English on HIVST with qualitative data from different African countries., Results: In total, 258 papers were retrieved, and only nine (9) studies conducted in 5 African countries were eligible and included in this synthesis. Perceived facilitators of the uptake of HIVST were autonomy and self-empowerment, privacy, confidentiality, convenience, opportunity to test, including couples HIV testing, and ease of use. The perceived barriers included the cost of buying self-test kits, perceived unreliability of test results, low literacy, fear and anxiety of a positive test result, and potential psychological and social harms. HIV stakeholder's concerns about HIVST included human right issues, lack of linkage to care, lack of face-to-face counseling, lack of regulatory and quality assurance systems, and quality of self-test kits. Actual HIVST users expressed preference of oral-fluid self-testing because of ease of use, and that it is less invasive and painless compared to finger-stick/whole blood-based HIV tests. Lack of clear instructions on how to use self-test kits, and existing different products of HIVST increases rates of user errors., Conclusions: Overcoming factors that may deter HIV testing, and HIVST, in particular, is complex and challenging, but it has important implications for HIV stakeholders, HIVST users, and public health in general. Research is warranted to explore the actual practices related to HIVST among different populations in Africa.
