Toxoplasmosis is an infection of warm-blooded vertebrates caused by the obligate intracellular protozoan parasite, Toxoplasma gondii. It is one of the most common parasitic diseases of humans, infecting approximately one-third of the world’s population. In persons with advanced HIV, toxoplasmosis represents a major opportunistic infection of the central nervous system. Approximately two-thirds of all people living with HIV live in sub-Saharan Africa. In areas such as this, toxoplasmosis could theoretically pose a huge threat. There is little known about T. gondii prevalence in humans in Africa. Geographically, prevalences vary widely on this continent, as observed in other parts of the world. There is limited historical information about the disease in South Africa. More knowledge is needed at a regional level about the risk of toxoplasmosis, diagnostic issues, and measures to reduce the risk to susceptible persons. The seroprevalence of T. gondii in selected populations, namely HIV-positive and HIV-negative individuals, and a more general sample biased towards pregnant women, was therefore investigated and found to be 9.8% (37/376), 12.8% (48/376) and 6.4% (32/497) respectively. Compared with historical data from South Africa, the prevalence has decreased substantially; however, the incidence of clinical disease is unknown, despite the very high burden of HIV and AIDS cases (5.9 million and 0.7 million, respectively in 2009). This study provided information relating to the diagnosis and current seroprevalence of T. gondii in South Africa. Many questions still remain to be answered however, to fully understand the impact of this parasite on the country’s population.

Purpose The purpose of this study is to explore the potential causes of HIV prevalence among young women in South Africa. Human immunodeficiency virus (HIV) is one of the leading causes of death in sub-Saharan Africa. South Africa (SA) has the largest HIV pandemic in the world with approximately 7.2 million people living with HIV as of 2017. There is a disproportionate incidence of HIV between women and men, particularly affecting young women 15–24 years of age. This paper reviewed 10 articles on the impact of HIV in SA among young women. Design/methodology/approach A total of 10 articles on HIV in SA were selected for review using academic databases including Library One Search Pro, Google Scholar, the British Medical Journal and Elsevier. The search generated 11,095 articles, which were narrowed down to 10 by the criteria of being specific to gender and age and publication period. Findings Five themes were identified from the findings as to the potential causes of HIV prevalence among young women these included age-disparate relationships, social factors and sexual behaviour. Impact of HIV on communities and individuals, gender and patriarchy including poverty and social isolation. Originality/value The paper shows the impact of inequalities between men and women leading to HIV infection among young women. It also shows some gaps that require further research with regards to HIV infections among young women.

Objective: The number of people living with HIV (PLWH) over 50 years old in sub-Saharan Africa is predicted to triple in the coming decades, to 6-10 million. Yet, there is a paucity of data on the determinants of health and quality of life for older PLWH in the region. Methods: A review was undertaken to describe the impact of HIV infection on aging for PLWH in sub-Saharan Africa. Results: We (a) summarize the pathophysiology and epidemiology of aging with HIV in resource-rich settings, and (b) describe how these relationships might differ in sub-Saharan Africa, (c) propose a conceptual framework to describe determinants of quality of life for older PLWH, and (d) suggest priority research areas needed to ensure long-term gains in quality of life for PLWH in the region. Conclusions: Differences in traditional, lifestyle, and envirnomental risk factors, as well as unique features of HIV epidemiology and care delivery appear to substantially alter the contribution of HIV to aging in sub-Saharan Africa. Meanwhile, unique preferences and conceptualizations of quality of life will require novel measurement and intervention tools. An expanded research and public health infrastructure is needed to ensure that gains made in HIV prevention and treamtent are translated into long-term benefits in this region.

Since its discovery in 1983, the human immunodeficiency virus (HIV) has been associated with a global pandemic that has affected more than 78 million people and caused more than 39 million deaths. Globally, 36.9 million (34.3–41.4 million) people were living with HIV at the end of 2013. An estimated 0.8% of adults aged 15–49 years worldwide are living with HIV, although the burden of the epidemic continues to vary considerably between countries and regions. Sub-Saharan Africa remains most severely affected, with nearly 1 in every 20 adults living with HIV and accounting for nearly 71% of the people living with HIV worldwide. The impact of HIV in some African countries has been sufficient to reverse population growth and reduce life expectancy into the mid-30s, although HIV incidence has declined in some of these high-prevalence countries. However, there are large-scale HIV epidemics elsewhere (e.g. India, the Russian Federation, and Eastern Europe).

One of the most challenging issues in dealing with HIV/AIDS in Africa is breaking through the stigmas surrounding the disease and building resilience in communities where large numbers of people are infected with HIV or otherwise affected by the pandemic. This article explores the relationship between shame, fear, guilt, witchcraft, and HIV/AIDS stigmatization by looking at key features of the African traditional worldview and culture. We point out predominant witchcraft beliefs and how they translate to community attitudes towards people living with HIV and AIDS. We highlight the influence of prevailing beliefs in witchcraft and how they aggravate the experience of fear, shame, and stigmatization by people infected with or otherwise affected by HIV. Relevant aspects of the gospel are brought to bear to answer these challenges. KEYWORDS: HIV/AIDS, stigmatization, shame culture, fear culture, witchcraft, ubuntu

AbstractAs the HIV and AIDS pandemic continues to affect most parts of Sub-Saharan Africa, the church has attempted to mitigate its effects. Unfortunately, stigma has emerged as a major challenge. The church has been implicated in stigmatizing people living with HIV and AIDS. Some Christians have used the Bible to justify the exclusion of people living with HIV and AIDS. This article examines HIV and AIDS stigma. It highlights the various forms of stigma, alongside exploring the occurrence of stigma in the Hebrew Bible. The study calls for a re-reading of the Hebrew Bible in the context of HIV and AIDS stigma and discrimination. It argues that the theme of liberation that underpins the Hebrew Bible implies that stigma has no place in human relations. The paper draws attention to the need to bring liberation to the heart of mission in the light of HIV and AIDS in Africa.

Abstract Background Mental health problems may impact adherence to anti-retroviral treatment, retention in care, and consequently the survival of adolescents living with HIV. The adolescent-caregiver relationship is an important potential source of resilience. However, there is a lack of longitudinal research in sub-Saharan Africa on which aspects of adolescent-caregiver relationships can promote mental health among adolescents living with HIV. We draw on a prospective longitudinal cohort study undertaken in South Africa to address this question. Methods The study traced adolescents aged 10–19 initiated on antiretroviral treatment in government health facilities (n = 53) within a health district of the Eastern Cape province. The adolescents completed standardised questionnaires during three data collection waves between 2014 and 2018. We used within-between multilevel regressions to examine the links between three aspects of adolescent-caregiver relationships (caregiver supervision, positive caregiving, and adolescent-caregiver communication) and adolescent mental health (depression symptoms and anxiety symptoms), controlling for potential confounders (age, sex, rural/urban residence, mode of infection, household resources), n=926 adolescents. Results Improvements in caregiver supervision were associated with reductions in anxiety (0.98, 95% CI 0.97–0.99, p=0.0002) but not depression symptoms (0.99, 95% CI 0.98–1.00, p=.151), while changes in positive caregiving were not associated with changes in mental health symptoms reported by adolescents. Improvements in adolescent-caregiver communication over time were associated with reductions in both depression (IRR=0.94, 95% CI 0.92–0.97, p<.0001) and anxiety (0.91, 95% CI 0.89–0.94, p<.0001) symptoms reported by adolescents. Conclusions Findings highlight open and supportive adolescent-caregiver communication and good caregiver supervision as potential factors for guarding against mental health problems among adolescents living with HIV in South Africa. Several evidence-informed parenting programmes aim to improve adolescent-caregiver communication and caregiver supervision, and their effect on depression and anxiety among adolescents living with HIV should be rigorously tested in sub-Saharan Africa. How to improve communication in other settings, such as schools and clinics, and provide communication support for caregivers, adolescents, and service providers through these existing services should also be considered.

Background:Despite demonstrating global concerns about infection in the workplace, very little research has explored how co-workers react to those living with HIV in the workplace in sub-Saharan Africa. This study aimed to assess the level of stigmatising attitude towards co-workers living with HIV in the workplace.Methods:The study was a descriptive cross-sectional survey involving 403 respondents. They were recruited from selected companies through a multistage sampling technique. Survey was carried out using pre-tested semi-structured questionnaires. Data were analyzed using the Statistical Package for the Social Sciences to generate frequencies, cross tabulations of variables at 5% level of significance. Logistic regression model was used to determine the predictors at 95% confidence intervals.Results:Mean age of respondents was 32.9 ± 9.4 years with 86.1% being females. Overall, slightly below two-third (63.0%) had good knowledge on transmission of HIV/AIDS while 218 (54.1%) respondents had a high stigmatising attitude towards co-workers with HIV in the workplace. More female respondents (69.6%) demonstrated high stigmatising attitudes towards co-workers with HIV in the workplace (p = 0.012). Female workers were twice more likely to have high stigmatising attitudes towards co-worker with HIV [OR 2.1 (95% CI: 1.13 – 3.83)].Conclusion:Stigma towards people living with HIV/AIDs is still very persistent in different settings. Good knowledge amongst our participants about HIV/AIDs did not translate to low stigmatising attitudes among workers. Concerted efforts and trainings on the transmission of HIV/AIDs are essential to reduce stigma that is still very prevalent in workplace settings.

Background: Good nutritional status is highly significant for individuals who are infected with HIV. However, they still face a number of nutritional challenges. The proposed scoping review will map literature on the nutritional challenges facing people living with HIV/AIDS (PLWH) and guide future research in nutritional management to improve health outcomes for PLWH. Here we outline a scoping review protocol designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P 2015 Guidelines).Methods: The Arksey and O’Malley’s 2005 scoping methodological framework further improved by Levac et al. 2010 will guide the search and reporting. Searches will be conducted for eligible articles from MEDLINE (PubMed), MEDLINE, CINAHL, Academic Search Complete and ISI Web of Science (Science Citation Index) electronic databases. Two independent reviewers will conduct the search guided by an inclusion and exclusion criteria. Quality appraisal of the included articles will be conducted guided by the mixed methods appraisal tool 2018 version. We will employ NVivo version 12 for thematic content analysis.Conclusions: The findings of this review will guide future research in nutritional management to improve health outcomes for PLWH in sub-Saharan African. This review will be disseminated electronically in a published peer reviewed article and in print.
