This paper rethinks a decolonial cosmopolitanism citizenship as a potentially useful heuristic to promote a planetary conviviality that could provide succour to humanity in a post COVID-19 world. The outbreak of the COVID- 19 pandemic in 2019 was followed by raced and xenophobic discourses as nations re-borderised in efforts to stem the pandemic. Such action resulted in trauma and acrimony on a planetary scale as the ideal of cosmopolitanism citizenship foundered on the altar of narrow selfish interest. It is aginst this backdrop that this paper seeks to foreground a decolonial cosmopolitan citizenship as part of a global imaginary for a post-COVID- 19 world. The argument developed is that decoloniality when intepellated with Ubuntu principles guarantees a cosmopolitan citizenship for a convivial re-existence in a post-COVID- 19 world.

- Abstract
The alarming reduction in drug effectiveness against bacterial infections has created an urgent need for the development of new antibacterial agents that circumvent bacterial resistance mechanisms. We report here a series of DNA gyrase and topoisomerase IV inhibitors that demonstrate potent activity against a range of Gram-positive and selected Gram-negative organisms, including clinically-relevant and drug-resistant strains. In part 1, we present a detailed structure activity relationship (SAR) analysis that led to the discovery of our previously disclosed compound, REDX05931, which has a minimum inhibitory concentration (MIC) of 0.06 μg mL−1against fluoroquinolone-resistant Staphylococcus aureus. Although in vitrohERG and CYP inhibition precluded further development, it validates a rational design approach to address this urgent unmet medical need and provides a scaffold for further optimisation, which is presented in part 2.

- Abstract
(1) Background: HIV drug resistance (HIVDR) poses a significant challenge to the effectiveness of antiretroviral therapy and the overall management of HIVand AIDS. Understanding the predictors of HIVDR is critical for developing strategies to mitigate its impact. The objectives of this study were to identify the predictors of HIVDR among Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA 2020) study participants, a national population-based survey. (2) Methods: Data from people living with HIV who participated in the ZIMPHIA 2020 were used to determine the predictors of HIVDR. (3) Results: The prevalence of HIVDR was 44.9%. Acquired HIVDR was present in 76.1% of people with a virological failure and transmitted resistance is 22.6% in naïve individuals. Factors associated with HIVDR in adjusted analysis were the number of lifetime sexual partners (aOR = 1.03, 95% CI: 1.01-1.06, p = 0.017), each additional year since the first HIV positive result (aOR = 1.17, 95% CI: 1.09-1.25, p < 0.01), each additional year on ART (aOR = 1.14, 95% CI: 1.06-1.23, p = 0.001), initiating ART before 2014 (aOR = 3.08, 95% CI: 1.72-5.49, p = 0.020), ever had switched antiretrovirals (aOR = 2.47, 95% CI: 1.15-5.29, p = 0.020) or had ever had a viral load test (aOR = 2.54, 95% CI: 1.54-4.17, p < 0.001) and a CD4 count < 350 (aOR = 2.04, 95% CI: 1.48-2.83, p < 0.01), while age ≥ 50 (aOR = 0.56, 95% CI: 0.32-0.98, 32 p = 0.04), condom use at last encounter (OR: 0.49, 95%CI: 0.33-0.73, p < 0.001), and not being on ART (aOR = 0.09, 95% CI: 0.06-0.13, p < 0.01) were associated with reduced odds of HIVDR. Conclusions: HIVDR was high among the participants. There is a need to address HIVDR and enhance the mechanisms already in place. This study introduces more information that would help in developing targeted interventions to prevent HIVDR and improve patient outcomes.

- Abstract
Background: Postnatal care (PNC) is a critical service for the health and well-being of new mothers and newborns. However, in sub-Saharan Africa (SSA), most efforts to improve maternal and child health have been directed toward enhancing skilled birth attendance and urgent obstetric and neonatal care. This is despite the fact that more than half of maternal deaths globally occur in the postnatal period, with 65% of these occurring in the first week following birth. One of the health system factors influencing PNC utilization is the women's previous PNC experience at healthcare facilities. The aim of this review was to gain a better understanding of women's experiences of PNC in SSA., Methods: This study followed a qualitative evidence synthesis design. The phenomenon of interest was postpartum women's experiences of PNC in SSA. PubMed, CINAHL, EMBASE, Science Direct, Africa Journals Online (AJOL), SCOPUS, and Google Scholar were searched for peer-reviewed articles published in English between 2013 and 2023. To assess the quality of the included studies, we used an appraisal tool developed by the Evidence for Policy and Practice Information and Co-ordinating Centre. Two authors independently extracted relevant data from the included studies. Thomas and Harden's thematic synthesis framework was used to synthesize the data., Results: Eight articles were used in this review. Seven articles reported on qualitative studies, and one reported on a mixed-method study. All the included studies fully or partially met the 12 quality assessment criteria. Synthesis of the data resulted in the development of five analytical themes. The five themes were the adequacy of physical examination and communication of the findings, adequacy of PNC information, the quality of interactions with healthcare workers (HCWs), the availability of resources and adequacy of HCWs, and denial of care. The overall confidence in the review's findings was either moderate or high., Conclusion: Based on our findings, we recommend that countries in the region address staff shortages, implement task shifting, electronic medicine stock management systems, optimal supply chain policies, and train HCWs on PNC and interpersonal communication skills., (© 2024 The Author(s).

- Abstract
In this paper, we explore the critical barriers that persons with disabilities face in accessing HIV services in the Eastern and Southern Africa (ESA) region, despite significant advancements in overall accessibility. We highlight the intersectional challenges experienced by individuals with disabilities, particularly women, and outline a comprehensive approach to bridge the existing gaps in policy and programmatic efforts. Specifically, we aim to address the exclusion of persons with disabilities from essential HIV prevention, treatment, and care services, a situation that has profound implications for their health, social inclusion, and economic productivity. In this discussion, we examine the current landscape, identify specific policy and programmatic hurdles, and propose targeted reforms, in an effort to contribute to the ongoing discourse on health equity and inclusivity., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

- Abstract
Background: Namibia, a low malaria transmission country targeting elimination, has made substantial progress in reducing malaria burden through improved case management, widespread indoor residual spraying and distribution of insecticidal nets. The country's diverse landscape includes regions with varying population densities and geographical niches, with the north of the country prone to periodic outbreaks. As Namibia approaches elimination, malaria transmission has clustered into distinct foci, the identification of which is essential for deployment of targeted interventions to attain the southern Africa Elimination Eight Initiative targets by 2030. Geospatial modelling provides an effective mechanism to identify these foci, synthesizing aggregate routinely collected case counts with gridded environmental covariates to downscale case data into high-resolution risk maps., Methods: This study introduces innovative infectious disease mapping techniques to generate high-resolution spatio-temporal risk maps for malaria in Namibia. A two-stage approach is employed to create maps using statistical Bayesian modelling to combine environmental covariates, population data, and clinical malaria case counts gathered from the routine surveillance system between 2018 and 2021., Results: A fine-scale spatial endemicity surface was produced for annual average incidence, followed by a spatio-temporal modelling of seasonal fluctuations in weekly incidence and aggregated further to district level. A seasonal profile was inferred across most districts of the country, where cases rose from late December/early January to a peak around early April and then declined rapidly to a low level from July to December. There was a high degree of spatial heterogeneity in incidence, with much higher rates observed in the northern part and some local epidemic occurrence in specific districts sporadically., Conclusions: While the study acknowledges certain limitations, such as population mobility and incomplete clinical case reporting, it underscores the importance of continuously refining geostatistical techniques to provide timely and accurate support for malaria elimination efforts. The high-resolution spatial risk maps presented in this study have been instrumental in guiding the Namibian Ministry of Health and Social Services in prioritizing and targeting malaria prevention efforts. This two-stage spatio-temporal approach offers a valuable tool for identifying hotspots and monitoring malaria risk patterns, ultimately contributing to the achievement of national and sub-national elimination goals., (© 2024.

- Abstract
An anticipated decline in external funding in sub-Saharan Africa (SSA) necessitates a re-evaluation of HIV response sustainability strategies. While institutional capacity building (ICB) has yielded positive outcomes, including strengthened technical expertise and institutional frameworks, it faces challenges. These include overemphasis on technical expertise neglecting resource mobilization, and a limited focus on policy advocacy. To achieve long-term sustainability, ICB efforts must equip local institutions with skills for tailored donor engagement, data-driven advocacy, and collaborative policy influence. This multi-pronged approach, coupled with efforts to diversify funding and integrate HIV responses, is crucial to empower local ownership and ensure the long-term viability of effective HIV responses in SSA., Competing Interests: Conflicts of interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Human papillomaviruses (HPV) cause 99% of all cervical cancer cases globally, with the high-risk genotypes 16 and 18 causing at least 70% of these cases. An estimated 90% of the global cervical cancer burden occurs in low-to-middle-income countries (LMICs), particularly in sub-Saharan Africa (SSA). Primary prevention through the administration of efficacious HPV vaccines is key to the World Health Organization's global strategy for accelerating the elimination of cervical cancer as a disease of public health concern. The rollout of HPV vaccination in SSA is faced with several challenges, such as the high cost of vaccine procurement, a lack of funding and political will from the central governments of countries, and inadequate infrastructure for vaccine cold chain storage and transport. Stigma, misinformation, lack of education and awareness, and vaccine hesitancy constitute the social factors that affect the successful rollout or implementation of vaccination programs in SSA. Based on the challenges SSA faces in rolling out HPV vaccination, we recommend using strategies that address both the demand-side and supply-side obstacles to HPV vaccination uptake. These include costs and availability, fighting vaccine hesitancy, and increasing vaccine confidence., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

- Abstract
Objectives: Access to safe drinking water, sanitation, and hygiene, collectively called WASH, is a fundamental human right and a cornerstone of public health. However, inadequate WASH practices and environments significantly contribute to the global burden of diarrheal diseases, particularly, in children aged under 5 years. Inadequate WASH conditions are the primary drivers of various infectious diseases, including cholera, dysentery, hepatitis A, typhoid, and polio., Methods: We conducted secondary data analysis using the 2019 Zimbabwe Multiple Indicator Cluster Survey to investigate the specific WASH risk factors associated with recent diarrheal episodes in children aged under 5 years., Results: A total of 853 (14%) of 6092 children were reported to have experienced an episode of diarrhea in the last 2 weeks preceding the survey. Having insufficient water in the household was associated with 17.0% diarrhea episodes compared with 13.6% in those who did not face this problem. The availability of soap or detergents to wash hands was associated with a risk of diarrhea, with an odds ratio and 95% confidence interval of 1.19 (1.01-1.40), P = 0.033. The use of surface water, including rivers, dams, lakes, ponds, streams, canals, and irrigation channels, was associated with differences in diarrheal episodes, although this was of borderline significance, P = 0.082. Of the children who had a recent episode of diarrhea, 41.0% had their parents or caregivers seeking medical attention., Conclusions: There is need for an improvement in safe water supply to households and an improvement in health education on the importance of using soap after using the toilet to avoid contamination of food and water., Competing Interests: The authors have no competing interests to declare., (© 2024 The Author(s).)

- Abstract
Migration, a prevalent global phenomenon, significantly impacts health, particularly in low- to middle-income countries. This article presents a rapid review aimed at mapping projects, lessons and policies concerning sexual and reproductive health (SRH), HIV and migration in southern Africa. Utilising a population-concept-context framework, the review focuses on understanding the scope, nature and extent of interventions, identifying lessons learnt, and assessing existing policies and strategies. A comprehensive search strategy and screening process resulted in 19 studies and reports for inclusion. The review highlighted diverse projects across southern Africa, addressing SRH and HIV among migrants, refugees and asylum seekers. Projects ranged from peer-education interventions to community-based referral systems, aiming to improve knowledge, access and outcomes related to SRH and HIV. The lessons learnt emphasised the importance of community involvement, healthcare worker (HCW) training and inclusive policies to address migrants' diverse needs effectively. Additionally, projects facilitated cross-border collaborations and policy integration, enhancing access to SRH-HIV services and migrant health rights. Despite these efforts, challenges persist, including gender-based violence, financial barriers and xenophobic attitudes among HCWs. Limited access to comprehensive sexuality education and social protection for migrants underscores the need for further policy development and implementation. Nevertheless, existing policies, such as Botswana's inclusive HIV treatment policy and South Africa's National Strategic Plan for HIV, TB and STIs, demonstrate steps towards ensuring migrants' rights to healthcare.

- Abstract
Purpose: This paper examines the impact of a scholarship program on underprivileged students, drawing on data from a two-year monitoring and evaluation (M&E) process. The report identifies both enablers and barriers to academic success among scholarship beneficiaries., Methods: Data on program impact was collected through interviews with parents, teachers, and school records over two academic years., Results: Financial aid emerged as a crucial enabler, with scholarships allowing students to focus on their studies by alleviating pressure around basic necessities. However, the research also revealed the importance of a holistic support system. Beyond tuition, the high cost of essential learning materials, including stationery, and subject-specific resources, can create a significant barrier. The study also highlighted the importance of student well-being. Health concerns, limited access to nutritious food, and even unaddressed mental health issues can all negatively impact attendance and focus. Furthermore, a gender gap emerged, with girls facing additional challenges related to social pressures to prioritize chores and the cost of menstrual hygiene products., Conclusion: This study highlights the importance of holistic scholarship programs that extend beyond tuition coverage. To maximize impact, policymakers and funders should prioritize initiatives that address the multifaceted needs of underprivileged students., (Copyright © 2024 Elsevier Ltd. All rights reserved.)

- Abstract
DNA viruses are common in the human population and act as aetiological agents of cancer on a large scale globally. They include the human papillomaviruses (HPV), Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpesvirus (KSHV), hepatitis viruses, and human polyomaviruses. Oncogenic viruses employ different mechanisms to induce cancer. Notably, cancer only develops in a minority of individuals who are infected, usually following protracted years of chronic infection. The human papillomaviruses (HPVs) are associated with the highest number of cancer cases, including cervical cancer and other epithelial malignancies. Hepatitis B virus (HBV) and the RNA virus hepatitis C (HCV) are significant contributors to hepatocellular cancer (HCC). Other oncoviruses include Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpes virus (KSHV), human T-cell leukemia virus (HTLV-I), and Merkel cell polyomavirus (MCPyV). The identification of these infectious agents as aetiological agents for cancer has led to reductions in cancer incidence through preventive interventions such as HBV and HPV vaccination, HPV-DNA based cervical cancer screening, antiviral treatments for chronic HBV and HCV infections, and screening of blood for transfusion for HBV and HCV. Successful efforts to identify additional oncogenic viruses in human cancer may provide further understanding of the aetiology and development of cancer, and novel approaches for prevention and treatment. Cervical cancer, caused by HPV, is the leading gynaecological malignancy in LMICs, with high age-standardised incidence and mortality rates, HCC due to HBV is an important cause of cancer deaths, and the burden of other cancer attributable to infections continues to rise globally. Hence, cancers attributable to DNA viruses have become a significant global health challenge. These viruses hence warrant continued attention and interrogation as efforts to understand them further and device further preventive interventions are critical., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Objectives: In recent years, mpox, a zoonotic disease caused by the mpox virus, has transcended its primary association with Central and West Africa, emerging as a global public health concern. The virus poses a substantial threat, particularly, to vulnerable demographics such as young children and individuals with compromised immune systems. This critical literature review aimed to comprehensively evaluate the burden, risk factors, and current management strategies associated with mpox in Africa., Methods: This critical literature review was guided by Jesson & Laccy's guidelines on conducting critical literature reviews. We searched PubMed and Google Scholar databases and websites of the World Health Organization and health ministries in different African countries. We included articles written in English and published between 2010 and 2023. The synthesis of findings involved several steps, including summarizing themes, integrating themes, and linking themes to research questions., Results: A total of 25 articles were included in this review. The review revealed that mpox cases are concentrated in Central African countries. The risk factors for mpox identified include being in contact with bushmeat or rodents, not having been vaccinated against smallpox, being HIV-positive, and having close physical contact with someone with the disease. The clinical presentation of mpox revealed in this review includes a skin rash, fever, lymphadenopathy, headache, pruritus, sore throat, and body aches. Four themes arose on strategies to prevent and control mpox in Africa., Conclusions: The prevention and control of mpox in Africa require an improvement in community education, vaccination, disease surveillance, and infection control measures., Competing Interests: The authors have no competing interests to declare., (© 2024 The Author(s).)

- Abstract
There is a substantial increase in sexually transmitted infections (STIs) among men who have sex with men (MSM) globally. Unprotected sexual practices, multiple sex partners, criminalization, stigmatisation, fear of discrimination, substance use, poor access to care, and lack of early STI screening tools are among the contributing factors. Therefore, this study applied multilayer perceptron (MLP), extremely randomized trees (ExtraTrees) and XGBoost machine learning models to predict STIs among MSM using bio-behavioural survey (BBS) data in Zimbabwe. Data were collected from 1538 MSM in Zimbabwe. The dataset was split into training and testing sets using the ratio of 80% and 20%, respectively. The synthetic minority oversampling technique (SMOTE) was applied to address class imbalance. Using a stepwise logistic regression model, the study revealed several predictors of STIs among MSM such as age, cohabitation with sex partners, education status and employment status. The results show that MLP performed better than STI predictive models (XGBoost and ExtraTrees) and achieved accuracy of 87.54%, recall of 97.29%, precision of 89.64%, F1-Score of 93.31% and AUC of 66.78%. XGBoost also achieved an accuracy of 86.51%, recall of 96.51%, precision of 89.25%, F1-Score of 92.74% and AUC of 54.83%. ExtraTrees recorded an accuracy of 85.47%, recall of 95.35%, precision of 89.13%, F1-Score of 92.13% and AUC of 60.21%. These models can be effectively used to identify highly at-risk MSM, for STI surveillance and to further develop STI infection screening tools to improve health outcomes of MSM., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Mugurungi et al.

- Abstract
HIV/AIDS remains one of the world's most significant public health and economic challenges, with approximately 36 million people currently living with the disease. Considerable progress has been made to reduce the impact of HIV/AIDS in the past years through successful multiple HIV/AIDS prevention and treatment interventions. However, barriers such as lack of engagement, limited availability of early HIV-infection detection tools, high rates of HIV/sexually transmitted infections (STIs), barriers to access antiretroviral therapy, lack of innovative resource optimisation and distribution strategies, and poor prevention services for vulnerable populations still exist and substantially affect the attainment of the UNAIDS 95-95-95 targets. A rapid review was conducted from 24 October 2022 to 5 November 2022. Literature searches were conducted in different prominent and reputable electronic database repositories including PubMed, Google Scholar, Science Direct, Scopus, Web of Science, IEEE Xplore, and Springer. The study used various search keywords to search for relevant publications. From a list of collected publications, researchers used inclusion and exclusion criteria to screen and select relevant papers for inclusion in this review. This study unpacks emerging opportunities that can be explored by applying machine learning techniques to further knowledge and understanding about HIV service design, prediction, implementation, and evaluation. Therefore, there is a need to explore innovative and more effective analytic strategies including machine learning approaches to understand and improve HIV service design, planning, implementation, and evaluation to strengthen HIV/AIDS prevention, treatment, and awareness strategies.

- Abstract
Background: Globally, there are about 800 maternal deaths every day, with low-to-middle-income countries accounting for most of these deaths. A lack of access to maternal healthcare services is one of the main causes of these deaths. In sub-Saharan Africa (SSA), one of the barriers to accessing maternal healthcare services by women is a lack of their male partners' involvement. This scoping review aimed to assess the enablers and barriers to men's involvement in maternal healthcare services., Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) checklist was used as a guide for this review. We searched for peer-reviewed articles published between 2013 and 2023 in the English language from SCOPUS, ScienceDirect, PubMed, Africa Journals Online (AJOL), and Google Scholar databases. Two reviewers independently conducted the data extraction and article selection. All of the authors discussed and decided on the codes and categories for enablers and barriers after using NVivo to generate them., Results: Twenty-seven articles were used in this review. Of these, seventeen were qualitative studies, six were quantitative studies, and four were mixed-methods studies. The enablers of men's involvement in maternal healthcare were grouped into sociodemographic factors, health system factors, and policy factors, while barriers were grouped into sociodemographic, cultural, economic, and health system barriers. The lack of maternal health knowledge, insufficient economic resources, and unfriendly staff at healthcare facilities all contributed to a lack of involvement by men., Conclusion: To improve men's involvement in maternal healthcare in SSA, there should be economic empowerment of both men and women, health education, and the provision of adequate infrastructure in healthcare facilities to accommodate men., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Background: The COVID-19 pandemic has wrought a profound impact on mental health in Sub- Saharan Africa, exacerbating existing disparities and rendering individuals undergoing treatment particularly susceptible. This comprehensive critical review delves into the scope, nature, and extent of COVID-19 impact on mental health services in Sub- Saharan Africa, while concurrently elucidating pivotal lessons and exemplary practices learnt from periods of lockdown., Methods: The methodology was guided by Jesson & Laccy's guide on how to conduct critical literature reviews. Articles were comprehensively sought through two academic databases (PubMed and Google Scholar), complemented by targeted searches on the WHO website and official public health websites of relevant Sub-Saharan African countries., Results: The investigation reveals a surge in mental health challenges, notably marked by a significant escalation in anxiety, depression, and post-traumatic stress disorder. Disruptions to care services, financial hardships, and the pervasive effects of social isolation further compound this escalation. The pre-existing inequalities in access to and quality of care were accentuated during this crisis, with marginalized groups encountering heightened impediments to essential services. In navigating this unprecedented challenge, communities emerged as integral agents in establishing supportive networks and implementing culturally sensitive interventions. Technology, such as telemedicine and online resources, played a pivotal role in bridging access gaps, particularly in remote areas. The synthesis of best practices for supporting mental health patients during lockdowns encompasses targeted interventions for vulnerable groups, including adolescents and pregnant women. Empowering communities through economic support and mental health literacy programs was identified as crucial. The integration of technology, such as the development of robust telemedicine frameworks, virtual training in curricula, and the utilization of digital platforms for interventions and public messaging, emerged as a cornerstone in addressing access disparities. Community engagement and resilience-building strategies gained prominence, emphasizing the necessity of collaboration between healthcare providers and communities. Promotion of peer support groups, home-based care, and the preservation of traditional healing practices were underscored as essential components., Conclusion: The study underscores the need to adapt and optimize mental health services during emergencies. This entails prioritizing mental health within emergency response frameworks, exploring alternative service delivery methods, and fortifying data collection and research efforts., (Copyright © 2024 The Authors.

- Abstract
COVID-19-related complications can last for years, even in patients who are asymptomatic during the acute phase, a phenomenon referred to as long COVID. This scoping review aimed to summarize the risk factors and clinical symptoms of long COVID in Africa between 2020 and 2022. Five studies were included. Three of the studies used in this review were retrospective cross-sectional studies, one was a prospective cohort study while another one was a case-control study. The review identified several risk factors for long COVID, including being female, being older than 40 years, having more than four acute COVID-19 symptoms, and having concomitant conditions such as asthma, hypertension, and depression. General, respiratory, cardiovascular, otolaryngological, gastrointestinal, and neurological symptoms were among the reported long COVID symptoms. To ensure that patients with long COVID are diagnosed and treated early, the risk factors and clinical symptoms of long COVID need to be identified for different population groups., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

- Abstract
The expected culmination of a positive pregnancy experience is a healthy mother and a bouncing live baby. Unfortunately, globally an estimated 2 million babies are still born every year, with the largest incidence of stillbirths of about 50% of the global burden occurring in sub-Saharan Africa (SSA). Significant gaps in access to quality antenatal care (ANC) and labour and delivery remain in SSA. It is estimated that only 24% of women receive at least four ANC visits in SSA. Women are prepared for labour and delivery during this period, and risk factors are identified, and potential complications can be averted. Access to labour and delivery services is critical for picking up foetal compromise. Women must deliver in facilities that can offer assisted delivery and offer foetal and neonatal resuscitation, to prevent stillbirths and early neonatal deaths. In SSA, many primary healthcare facilities are unable to offer these services, whilst higher level facilities that can offer these may be difficult to access. The majority of stillbirths are preventable if women access quality ANC and can access modern facilities for labour and delivery. Therefore, stakeholders in reproductive health must ensure access to ANC for a positive pregnancy experience., Competing Interests: The Authors declared no conflict of interest, (African Journal of Reproductive Health © 2023.)

- Abstract
In May 2023, the World Health Organization announced that COVID-19 was no longer a global emergency. The impact of COVID-19 on the provision of HIV/AIDS services was not that severe due to the reprogramming of key resources. For health systems in sub-Saharan Africa to become resilient to future pandemics, lessons should be learned from the successful HIV/AIDS response in the region, and how the HIV/AIDS services were successfully adapted to the COVID-19 pandemic. In this article, we reviewed the 6 World Health Organization health system building blocks on how the best practices from the provision of HIV/AIDS services and the services' response to the COVID-19 pandemic can be used as a basis for restoring and strengthening health systems to offer universal access to quality essential health services. The success of the leadership and governance for universal access to anti-retroviral therapy can be a blueprint for the realization of universal health coverage. Significant efficiencies that resulted in the reduction in anti-retroviral therapy costs can be leveraged to ensure cheaper essential drugs while differentiated service delivery models can be used to improve health service accessibility. New technologies that have proven to be successful in HIV/AIDS care can also be used in the care of other diseases, including disease outbreaks. The strong health information systems developed for HIV programs can be used as a foundation for developing health information systems for the whole health sector while the healthcare professionals trained for the provision of HIV/AIDS services can be trained to provide services for a variety of other conditions., Competing Interests: The authors have no competing interests to declare., (© 2023 The Author(s).)

- Abstract
Control measures for the COVID-19 pandemic brought unprecedented challenges to health care delivery. Some countries in sub-Saharan Africa (SSA) stopped the provision of essential health care except for those services that were deemed emergencies or life-threatening. A rapid review was conducted on March 18, 2022, on the accessibility and utilization of antenatal care services in sub-Saharan Africa during the COVID-19 pandemic. PubMed, Google Scholar, SCOPUS, and the World Health Organization library databases were searched for relevant studies. A modified Population, Intervention, Control, and Outcomes (PICO) framework informed the development of the search strategy. The review included studies conducted within Africa that described the availability, access, and utilization of antenatal services during the COVID-19 pandemic. Eighteen studies met the inclusion criteria. This review revealed a reduction in access to ANC services, an increase in the number of home deliveries, and a reduction in the number of women attending ANC visits during the COVID-19 pandemic. A decrease in ANC service utilization was reported in some studies in the review. Barriers to ANC access and utilization during the COVID-19 pandemic included movement restrictions, limited transport access, fear of contracting COVID-19 at the health facilities, and facility barriers. The use of telemedicine needs to be improved in African countries to allow for the continued provision of health services during pandemics. In addition, there should strengthening of community involvement in the provision of maternal health services post-COVID-19 so that services may be able to better withstand future public health emergencies., (© 2023 The Authors.

- Abstract
Introduction: The burden of HIV in sub-Saharan Africa (SSA) remains unacceptably high, and disproportionately affects girls and women. While the introduction of oral HIV pre-exposure prophylaxis (PrEP) in 2012 revolutionized HIV prevention, its effectiveness is dependent on user adherence and its implementation in SSA has faced numerous challenges. Patient-level, interpersonal and structural barriers, including, for example, daily pill burden, side effects, lack of partner support, testing and disclosure, and costs have been found to reduce adherence to oral PrEP., Discussion: Long-acting extended delivery (LAED) formulations for PrEP, such as injectable long-acting cabotegravir (CAB-LA) and dapivirine vaginal ring (DPV-VR) are critical additions to the HIV prevention toolkit and are especially important for populations such as adolescent girls and young women (AGYW) and other key populations who remain at significant risk of HIV acquisition while facing substantial barriers to preventive services. These LAED formulations have been shown to result in better adherence and fewer side effects, with CAB-LA being superior to oral PrEP in reducing the risk of HIV acquisition. They can be used to overcome user burden and adherence challenges. However, the successful rollout of the DPV-VR and CAB-LA may be hampered by issues such as a shortage of healthcare providers (HCPs), inadequate parenteral medication infrastructure, increased workload for HCPs, patient concerns, the price of the medications and the possibility of drug resistance., Conclusions: SSA must develop laboratory capabilities for monitoring patients on LAED formulations and enhance research on developing more non-injectable LAED formulations. There is a need to train and retain more HCPs, implement task shifting, invest in healthcare infrastructure and integrate healthcare services. To reduce costs and improve availability, the region must advocate for patent license waivers for LAED formulations and procure drugs collectively as a region., (© 2023 The Authors.

- Abstract
Objectives: The sustainable development goals launched in 2015 are a follow-up commitment to the successful Millennium Development Goals. Goal number 3 of ensuring "good health and well-being" is a target to ensure universal health coverage. Universal health coverage means the provision of quality services that meet the needs of populations without risking financial impoverishment in the process. The guaranteed minimum health services in every health system constitute the health benefits package (HBP), which should be explicit and be composed of services that represent the best value for money and guarantee the best return on investment. The objective of this study was to review the application of cost-effectiveness analysis (CEA) and budget impact analysis in the development of HBP in low-to-middle income countries across the world., Methodology: A literature review using a systematic approach was used. A search of PubMed, Google Scholar, World Health Organization, and World Bank databases was made for articles outlining the development of HBP in low- and middle-income countries, and a narrative synthesis was used for analysis., Results: Results from processes in Armenia, Ethiopia, Kyrgyz Republic, Lebanon, and Malawi showed CEA and budget impact analysis as 2 criteria used in HBP development in a limited number of countries with either no reference to the two or no reporting from the others. Local CEA estimates and cost data limitations were the biggest challenges to efforts to use robust methods., Conclusion: Sustained efforts are needed to understand and address the challenges to the use of economic evaluation in the development of HBPs., (Copyright © 2023 International Society for Health Economics and Outcomes Research.

- Abstract
The world's climate, particularly in Africa, has changed substantially during the past few decades, contributed by several human activities. Africa is one of the continents that is most vulnerable to climate change globally. Since the beginning of 2022, extreme weather events in Africa have affected about 19 million people and killed at least 4,000 individuals. Cyclones, floods, heatwaves, wildfires, droughts, and famine were among the severe weather occurrences. Natural disasters and extreme weather events brought on by climate change may compromise access to clean water, sanitation systems, and healthcare facilities, making people more vulnerable to a number of illnesses. Floods and drought can lead to both communicable and non-communicable diseases. The African population is more likely to experience more mental health disorders than before because of natural disasters, which result in the loss of property and sometimes loss of lives more frequently. We, therefore, call for an improved implementation of strategies to prevent the health effects of climate change so that the health of the people in Africa can be maintained., Competing Interests: The authors have declared no conflicts of interest., (© 2023 The Author(s).)

- Abstract
Background: Considerable progress has been made globally in improving maternal and newborn babies' health. The COVID-19 pandemic has posed considerable challenges for countries to maintain the provision of high-quality, essential maternal and newborn healthcare services., Methods: A rapid review was carried out on 20 March 2022 on postnatal care (PNC) services availability and utilization during the COVID-19 era in sub-Saharan Africa. PubMed, Google Scholar, and Africa Journals Online (AJOL) databases were searched for relevant studies. Studies included in the review utilized both primary data and secondary data., Findings: Nineteen studies met the inclusion criteria. The review revealed that there were significant declines in the availability and utilization of PNC services during and after the COVID-19 lockdown. Several reasons were found to contribute to the decline., Discussion: New, innovative strategies are therefore required to ensure that mothers and their newborn babies receive essential PNC to reduce maternal and neonatal morbidity and mortality in sub-Saharan Africa. Some of the strategies that can be used include home-based PNC visits, the use of telemedicine, phone-based referral networks, social media, and community radios., Competing Interests: Conflict of interest None declared., (Copyright © 2022 Australian College of Midwives.

- Abstract
Sub-Saharan Africa has the highest rates of cervical cancer in the world, largely attributed to low cervical cancer screening coverage. Cervical cancer is the most common cause of death among women in 21 of the 48 countries in sub-Saharan Africa. Close to 100% of all cases of cervical cancer are attributable to Human papillomavirus (HPV). HPV types 16 and 18 cause at least 70% of all cervical cancers globally, while types 31, 33, 45, 52, and 58 cause a further 20% of the cases. Women living with HIV are six times more likely to develop cervical cancer than those without HIV. Considering that sub-Saharan Africa carries the greatest burden of cervical cancer, ways to increase accessibility and use of preventive services are urgently required. With this review, we discuss the preventive measures required to reduce the burden of cervical cancer in sub-Saharan Africa, the challenges to improving accessibility and use of the preventive services, and the recommendations to address these challenges., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2023.

- Abstract
Antibiotics help in preventing and treating infections and increasing life expectancy globally. Globally, many people's lives are being threatened by the emergence of antimicrobial resistance (AMR). The cost of treating and preventing infectious diseases has increased due to AMR. Bacteria can resist the effects of antibiotics by altering drug targets, inactivating drugs, and activating drug efflux pumps. According to estimates, five million individuals died in 2019 from AMR-related causes, wherein 1.3 million deaths were directly linked to bacterial AMR. Sub-Saharan Africa (SSA) experienced the greatest mortality rate from AMR in 2019. In this article, we discuss AMR's causes and challenges SSA faces in implementing AMR prevention measures and propose recommendations to address the challenges. Antibiotic misuse and overuse, widespread usage in agriculture, and the pharmaceutical industry's absence of new antibiotic development are the factors contributing to AMR. SSA's challenges in preventing AMR include poor AMR surveillance and lack of collaboration, irrational use of antibiotics, weak medicine regulatory systems, lack of infrastructural and institutional capacities, lack of human resources, and inefficient infection prevention and control (IPC) practices. The challenges faced by countries in SSA can be addressed by increasing the public's knowledge of antibiotics and AMR, promoting antibiotic stewardship, improving AMR surveillance, promoting collaboration within and beyond countries, antibiotics regulatory enforcement, and improving the practice of IPC measures at home, food handling establishments, and healthcare facilities., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

- Abstract
Public Health Genomics (PHG) is a relatively new field. The wide application of genomic technologies played a pivotal role in elucidating the full genomic sequence of the SARS-CoV-2 virus. This breakthrough proved to be the starting point in the manufacture of diagnostic kits and the subsequent making of vaccines. Beyond the COVID-19 pandemic, many African countries can take advantage of the various investments in genomic technologies to introduce and intensify the use of genomics for public health gain. Public Health Genomics effectively monitors, prevents, and manages non-communicable and infectious diseases. However, there are several challenges to implementing PHG in Africa. In this perspective article, we discuss the utilization of PHG during the COVID-19 pandemic, the lessons learned from using PHG to manage and contain the COVID-19 pandemic, as well as potential challenges Africa may face when putting PHG into practice compared to challenges of other regions. We also discuss our recommendations for overcoming these challenges., (© 2022 Wiley Periodicals LLC.)

- Abstract
Although there has been a global reduction in wild poliovirus (WPV) type 1 cases, Africa has experienced a re-emergence of the disease. This article discusses the re-emergence of WPV in Africa, the transmission and pathogenesis of WPV, and the role of environmental surveillance and other strategies used to interrupt all WPV transmission in the region permanently., (© 2022 The Author(s).)

- Abstract
Background: An abnormal vaginal discharge is a frequent manifestation of reproductive tract infections, including sexually transmitted infections (STIs) and vulvovaginal candidiasis. It is also a manifestation of bacterial vaginosis, which has a prevalence of up to 50% among women of reproductive age. Reproductive tract infections are associated with a range of reproductive health challenges and increase the risk of HIV acquisition., Methods: This study was performed to critically review and discuss the current diagnostic and treatment approaches to abnormal vaginal discharge among women of reproductive age in sub-Saharan Africa, and to call for a paradigm shift from the syndromic approach to specific pathogen identification and directed antimicrobial therapy., Discussion: Young women have the highest incidence of HIV infection in sub-Saharan Africa. Countries in sub-Saharan Africa where the prevalence of both STIs and bacterial vaginosis is very high have been employing a syndromic approach for the treatment of abnormal vaginal discharge since around 1984. However, the syndromic approach has several limitations, with the potential to miss infections, over-diagnose and over-treat STIs, and propagate antimicrobial resistance, which is one of the greatest global health challenges of the 21
st century., Conclusions: The low to middle-income countries of sub-Saharan Africa must innovate and leverage improved diagnostics to capacitate primary health care and other levels for point-of-care diagnostic testing, in order to provide an immediate diagnosis and treatment for women with an abnormal vaginal discharge., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reportcoed in this paper., (© 2022 The Author(s).)- Published
