Brief Report: Self-Reported HIV-Positive Status but Subsequent HIV-Negative Test Results in Population-Based HIV Impact Assessment Survey Participants-11 Sub-Saharan African Countries, 2015-2018.

Background: HIV testing is a critical step to accessing antiretroviral therapy (ART) because early diagnosis can facilitate earlier initiation of ART. This study presents aggregated data of individuals who self-reported being HIV-positive but subsequently tested HIV-negative during nationally representative Population-Based HIV Impact Assessment surveys conducted in 11 countries from 2015 to 2018.

Method: Survey participants aged 15 years or older were interviewed by trained personnel using a standard questionnaire to determine HIV testing history and self-reported HIV status.

Building Research Capacity in Low- and Middle-Income Countries and Pandemic Preparedness: Lessons Learned and Future Directions.

Research capacity is a critical component of pandemic preparedness, as highlighted by the challenges faced during the Ebola outbreak in West Africa. Recent global initiatives, such as the Research & Development Task Force of the Global Health Security Agenda and the World Health Assembly's resolution on strengthening clinical trials, emphasize the need for robust research capabilities. This Perspective discusses the experiences of leaders in infectious disease research and capacity building in low- and middle-income countries, focusing on Colombia, Jamaica, and Pakistan.

Global HIV control: is the glass half empty or half full?

The massive scale-up of HIV treatment and prevention over the past two decades has resulted in important reductions in new infections and mortality globally. Reduction in HIV incidence, however, has been unequal, with worsening epidemics in regions where the reach and scale of HIV control programmes have been insufficient, especially in eastern Europe, central Asia, the Middle East, north Africa, and Latin America where HIV epidemics are concentrated among key populations, including people who inject drugs, men who have sex with men, transgender people, and some minority racial and ethnic groups. The global state of the HIV pandemic highlights disparities in HIV control efforts and provides a roadmap for what should be done, including investment to better implement the effective HIV prevention and treatment tools that are available, but whose adoption and scale-up are not yet sufficient to get us close to an AIDS-free generation.

The epidemiology of HIV population viral load in twelve sub-Saharan African countries.

Background: We examined the epidemiology and transmission potential of HIV population viral load (VL) in 12 sub-Saharan African countries.

Methods: We analyzed data from Population-based HIV Impact Assessments (PHIAs), large national household-based surveys conducted between 2015 and 2019 in Cameroon, Cote d'Ivoire, Eswatini, Kenya, Lesotho, Malawi, Namibia, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe. Blood-based biomarkers included HIV serology, recency of HIV infection, and VL.

Increasing Effectiveness and Equity in Strengthening Health Research Capacity Using Data and Metrics: Recent Advances of the ESSENCE Mechanism.

Background: The ESSENCE on Health Research initiative established a Working Group on Review of Investments in 2018 to improve coordination and collaboration among funders of health research capacity strengthening. The Working Group comprises more than a dozen ESSENCE members, including diverse representation by geography, country income level, the public sector, and philanthropy.

Objective: The overall goal of the Working Group is increased research on national health priorities as well as improved pandemic preparedness, and, ultimately, fewer countries with very limited research capacity.

Advancing Adolescent HIV Prevention and Care Through Implementation Science: An Agenda for Combating the Global AIDS Epidemic in Sub-Saharan Africa.

AIDS continues to be a major driver of adolescent mortality in Sub-Saharan Africa. Despite evidence of efficacy in this population, many efforts to address adolescent HIV have had limited impact across the region because of difficulty with implementation. The field of implementation science holds promise for addressing these challenges.

Bibliometric Analysis of Authorship of Publications About Sub-Saharan Africa Published in the Journal Sexually Transmitted Diseases , 2011 to 2020.

Background: As a potential indicator of equity in research partnerships, we conducted a bibliometric analysis of author affiliations and author order in publications about sub-Saharan Africa published in the journal Sexually Transmitted Diseases .

Methods: We identified articles in the journal Sexually Transmitted Diseases that were about sub-Saharan Africa and published from 2011 to 2020. Medical Subject Heading terms in PubMed were used to identity articles about sub-Saharan Africa.

Advancing detection and response capacities for emerging and re-emerging pathogens in Africa.

Recurrent disease outbreaks caused by a range of emerging and resurging pathogens over the past decade reveal major gaps in public health preparedness, detection, and response systems in Africa. Underlying causes of recurrent disease outbreaks include inadequacies in the detection of new infectious disease outbreaks in the community, in rapid pathogen identification, and in proactive surveillance systems. In sub-Saharan Africa, where 70% of zoonotic outbreaks occur, there remains the perennial risk of outbreaks of new or re-emerging pathogens for which no vaccines or treatments are available.

Bibliometric analysis of sub-Saharan African and US authorship in publications about sub-Saharan Africa funded by the Fogarty International Center, 2008-2020.

Background: Authorship and author order have been used as one measure to characterise equity in research partnerships. First and last (senior) authorships often denote scientific merit as well as potential for research career advancement. A previous analysis found that only about 20%-25% of publications about Africa with coauthors from top-ranking US universities had a first or last author from the topic country.

What Do Global Health Practitioners Think about Decolonizing Global Health?

The growing awareness of colonialism's role in global health partnerships between HICs and LMICs and the associated calls for decolonization in global health has led to discussion for a paradigm shift that would lead to new ways of engagement and partnerships, as well as an acknowledgement that colonialism, racism, sexism, and capitalism contribute to inequity. While there is general agreement among those involved in global health partnerships that the current system needs to be made more equitable, suggestions for how to address the issue of decolonization vary greatly, and moving from rhetoric to reform is complicated. Based on a comprehensive (but not exhaustive) review of the literature, there are several recurring themes that should be addressed in order for the inequities in the current system to be changed.

Opportunities and Challenges in North-South and South-South Global Health Collaborations During the COVID-19 Pandemic: The AFREhealth-CUGH Experience (as Reported at the CUGH 2021 Satellite Meeting).

Sustainable and equitable partnerships and collaborations between the Global North and Global South (as well as within the Global South) have been aspirations (if seldom achieved) of the "global health" endeavor over the past couple of decades. The COVID-19 pandemic led to global lockdowns that disrupted international travel and severely challenged these partnerships, providing a critical space for self-reflection on global health as a discipline. One major global north-south partnership is that between the African Forum for Research and Education in Health (AFREhealth) and the Consortium of Universities for Global Health (CUGH).

Building global health research capacity to address research imperatives following the COVID-19 pandemic.

Peter Kilmarx and Roger Glass discuss strengthening health research capabilities as a response to the COVID-19 pandemic.

A National Public Health Workforce to Control COVID-19 and Address Health Disparities in the United States.

A large, well-trained public health workforce is needed to control coronavirus disease 2019 (COVID-19) in the United States in the short term and to address other disease burdens and health disparities in the long run. As the public health workforce declined following the 2008 financial crisis, many US jurisdictions struggled to hire a sufficient number of staff for roles initially including testing and contact tracing and more recently for vaccination. Ultimately, COVID-19 control will require a combination of vaccination and rapid investigation, contact tracing, and quarantine to stop chains of transmission.

Return of Positive Test Results to Participants in Sexually Transmitted Infection Prevalence Studies: Research Ethics and Responsibilities.

Background: In prevalence studies of sexually transmitted infections (STIs), investigators often provide syndromic management for symptomatic participants but may not provide specific treatment for asymptomatic individuals with positive laboratory test results because of the delays between sample collection and availability of results as well as logistical constraints in recontacting study participants.

Methods: To characterize the extent of this issue, 80 prevalence studies from the World Health Organization's Report on Global Sexually Transmitted Infection Surveillance, 2018, were reviewed. Studies were classified as to whether clinically relevant positive results were returned or if this was not specified.

Contact Tracing and the COVID-19 Response in Africa: Best Practices, Key Challenges, and Lessons Learned from Nigeria, Rwanda, South Africa, and Uganda.

Most African countries have recorded relatively lower COVID-19 burdens than Western countries. This has been attributed to early and strong political commitment and robust implementation of public health measures, such as nationwide lockdowns, travel restrictions, face mask wearing, testing, contact tracing, and isolation, along with community education and engagement. Other factors include the younger population age strata and hypothesized but yet-to-be confirmed partially protective cross-immunity from parasitic diseases and/or other circulating coronaviruses.

A Mechanism for Reviewing Investments in Health Research Capacity Strengthening in Low- and Middle-Income Countries.

More than 40 agencies that fund health research capacity strengthening in low- and middle-income countries (LMICs) participate in the ESSENCE Health Research initiative, which has established a mechanism for reviewing and coordinating their funding. Taken together, the expected outcomes of implementation of the review mechanism are increases in the efficiency and equity in health research capacity strengthening activities with decreased duplication of efforts. The overall goal is increased support of research on national health priorities as well as improved pandemic preparedness in LMICs, and, eventually, fewer countries with very limited research capacity.

Comparison of HIV Incidence in the Zimbabwe Population-Based HIV Impact Assessment Survey (2015-2016) with Modeled Estimates: Progress Toward Epidemic Control.

Between October 2015 and August 2016, Zimbabwe conducted the Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA) cross-sectional survey to determine progress toward epidemic control. Of 25,131 eligible adults aged 15-64 years, 20,577 (81.8%) consented to face-to-face questionnaire and biomarker testing in this nationally representative household survey.

Estimating the Population Size of Female Sex Workers in Zimbabwe: Comparison of Estimates Obtained Using Different Methods in Twenty Sites and Development of a National-Level Estimate.

Background: National-level population size estimates (PSEs) for hidden populations are required for HIV programming and modelling. Various estimation methods are available at the site-level, but it remains unclear which are optimal and how best to obtain national-level estimates.

Setting: Zimbabwe.

Mother-To-Child Transmission of HIV in Adolescents and Young Women: Findings From a National Prospective Cohort Survey, Zimbabwe, 2013-2014.

Purpose: We assessed 18-month cumulative mother-to-child HIV transmission (MTCT) risk and risk factors for no antiretroviral medication use during pregnancy among adolescent, young women, and adult mothers in Zimbabwe.

Methods: We analyzed data from a prospective survey of 1,171 mother-infant pairs with HIV-exposed infants aged 4-12 weeks who were recruited from 151 immunization clinics from February to August 2013. HIV-exposed infants were followed until diagnosed with HIV, death, or age 18 months.
