South Africa became one of the first African countries to receive the COVID-19 vaccine. As the rest of Africa prepares to receive COVID-19 vaccines, most countries in Africa have set up national-level coordination committees for developing national vaccination deployment plans. While the main focus of these committees has been on setting up strategies that facilitate the swift distribution of COVID-19 vaccines once they are available, the role of effective public health awareness should not be ignored. Countries must devise strategies on how best to enhance public understanding and curb misinformation about the vaccines. With this viewpoint, we unpack the threat of COVID-19 vaccine hesitancy and offer recommendations for COVID-19 vaccine communication strategies in the South African and Zimbabwean contexts.

As its usage has grown, social media has positively and negatively impacted public health. Although social media presents known harms to mental health and spreads misinformation, it also offers rapid dissemination of public health information, expanded access to health resources, and a robust source of health information. However, these benefits are not equitably shared due in part to the “digital divide” of unequal access and use of information and communication technologies. Measurable inequalities in digital access exist among regions, with an eight-fold difference between Central Africa (9.8% social media penetration) and Northern Europe (80.2% social media penetration). Digital inequalities also differ by gender, age, and socioeconomic classes within countries. Increased digital access has been positively associated with improved health information and outcomes related to chronic diseases, infectious disease outbreaks, and reproductive health. Given the expanding role of social media in public health and the emerging evidence on the health benefits of digital access, we argue for reducing digital inequities by (1) creating an enabling government policy and regulatory environment that views digital health access as a social determinant of health; (2) targeting public and private investments to expand digital access for underserved regions and populations; (3) making digital access and use affordable to low-resource populations; and (4) improving digital competency among these groups through digital literacy programs.

The role of geographical disparities of health-related risk factors with anemia are poorly documented for women of reproductive age in sub-Saharan Africa (SSA). We aimed to determine the contribution of potential factors and to identify areas at higher risk of anemia for women in reproductive age in SSA. Our study population comprised 27 nationally representative samples of women of reproductive age (15–49) who were enrolled in the Demographic and Health Surveys and conducted between 2010 and 2019 in SSA. Overall, we found a positive association between being anemic and the ecological exposure to malaria incidence [adjusted odds ratio (AOR) = 1.02, 95% confidence interval (CI) 1.02–1.02], and HIV prevalence (AOR = 1.01, CI 1.01–1.02). Women currently pregnant or under deworming medication for the last birth had 31% (AOR = 1.31, CI 1.24–1.39) and 5% (AOR = 1.05, CI 1.01–1.10) higher odds of having anemia, respectively. Similarly, women age 25–34 years old with low education, low income and living in urban settings had higher odds of having anemia. In addition, underweight women had 23% higher odds of suffering anemia (AOR = 1.23, CI 1.15–1.31). Females with low levels of education and wealth index were consistently associated with anemia across SSA. Spatial distribution shows increased risk of anemia in Central and Western Africa. Knowledge about the contribution of known major drivers and the spatial distribution of anemia risk can mitigate operational constraints and help to design geographically targeted intervention programs in SSA.

The emergence and fast global spread of COVID-19 has presented one of the greatest public health challenges in modern times with no proven cure or vaccine. Africa is still early in this epidemic, therefore the extent of disease severity is not yet clear. We used a mathematical model to fit to the observed cases of COVID-19 in South Africa to estimate the basic reproductive number and critical vaccination coverage to control the disease for different hypothetical vaccine efficacy scenarios. We also estimated the percentage reduction in effective contacts due to the social distancing measures implemented. Early model estimates show that COVID-19 outbreak in South Africa had a basic reproductive number of 2.95 (95% credible interval [CrI] 2.83-3.33). A vaccine with 70% efficacy had the capacity to contain COVID-19 outbreak but at very higher vaccination coverage 94.44% (95% Crl 92.44-99.92%) with a vaccine of 100% efficacy requiring 66.10% (95% Crl 64.72-69.95%) coverage. Social distancing measures put in place have so far reduced the number of social contacts by 80.31% (95% Crl 79.76-80.85%). These findings suggest that a highly efficacious vaccine would have been required to contain COVID-19 in South Africa. Therefore, the current social distancing measures to reduce contacts will remain key in controlling the infection in the absence of vaccines and other therapeutics.

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. 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. 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. 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. •COVID-19 impact on mental health service delivery is critically and comprehensively assessed.•Vulnerabilities of mental health care as discussed.•Inequitable access, and long-term consequences of COVID-19 on mental health emerged.•Addressing the digital divide hindering the adoption of alternative service delivery models was key.

Sub-Saharan Africa carries the highest burden of HIV-1 and AIDS. About 39% of all new infections in the world in 2020 were in this region. Oral PrEP was found to be very effective in reducing the risk of HIV-1 transmission. However, its effectiveness is highly dependent on users adhering to the drugs. The availability of long-acting injectable PrEP that eliminates the need for a daily pill may increase PrEP uptake and adherence in people who struggle to adhere to oral PrEP. The USA's FDA approved long-acting cabotegravir (CAB-LA) for PrEP of HIV-1 in December 2021. In this review, we discussed the implementation challenges to the successful roll-out of CAB-LA in Africa and measures to address these implementation challenges. Some health system-level challenges include the cost of the drug, its refrigeration requirement, and the shortage of healthcare providers trained to administer parenteral medicines. In contrast, client challenges include lack of knowledge, accessibility of the drug, side effects, stigma, and lack of family and community support. These challenges can be addressed by several measures emanating from lessons learned from the successful implementation of ART, oral PrEP, and immunization in the continent. Some steps include advocating for waiving of CAB-LA patent licence, conducting demonstration projects in Africa, promoting the use of renewable energy sources such as solar energy, healthcare provider training, task shifting, community engagement, client education, and implementing adherence promotion strategies.

Understanding the burden of SARS-CoV-2 infections among healthcare workers is a critical component to inform occupational health policy and strategy. We conducted a systematic review and meta-analysis to map and analayse the available global evidence on the prevalence of SARS-CoV-2 infections among healthcare workers. The random-effects adjusted pooled prevalence of COVID-19 among those studies that conducted the test using the antibody (Ab) method was 7% [95% CI: 3 to 17%]. The random-effects adjusted pooled prevalence of COVID-19 among those studies that conducted the test using the PCR method was 11% [95% CI: 7 to 16%]. We found the burden of COVID-19 among healthcare workers to be quite significant and therefore a cause for global health concern. Furthermore, COVID-19 infections among healthcare workers affect service delivery through workers’ sick leave, the isolation of confirmed cases and quarantine of contacts, all of which place significant strain on an already shrunken health workforce.

Zimbabwe has made large strides in addressing HIV. To ensure a continued robust response, a clear understanding of costs associated with its HIV program is critical. We conducted a cross-sectional evaluation in 2017 to estimate the annual average patient cost for accessing Prevention of Mother-To-Child Transmission (PMTCT) services (through antenatal care) and Antiretroviral Treatment (ART) services in Zimbabwe. Twenty sites representing different types of public health facilities in Zimbabwe were included. Data on patient costs were collected through in-person interviews with 414 ART and 424 PMTCT adult patients and through telephone interviews with 38 ART and 47 PMTCT adult patients who had missed their last appointment. The mean and median annual patient costs were examined overall and by service type for all participants and for those who paid any cost. Potential patient costs related to time lost were calculated by multiplying the total time to access services (travel time, waiting time, and clinic visit duration) by potential earnings (US $75 per month assuming 8 hours per day and 5 days per week). Mean annual patient costs for accessing services for the participants was US$ 20.00 [standard deviation (SD) = US $80.42, median = US$ 6.00, range = US $0.00–US$ 12,18.00] for PMTCT and US $18.73 (SD = US$ 58.54, median = US $8.00, range = US$ 0.00–US $ 908.00) for ART patients. The mean annual direct medical costs for PMTCT and ART were US$ 9.78 (SD = US $78.58, median = US$ 0.00, range = US $0.00–US$90) and US $7.49 (SD = US$ 60.00, median = US $0.00) while mean annual direct non-medical cost for US$ 10.23 (SD = US $17.35, median = US$ 4.00) and US $11.23 (SD = US$ 25.22, median = US $6.00, range = US$ 0.00–US $ 360.00). The PMTCT and ART costs per visit based on time lost were US$ 3.53 (US $1.13 to US$ 8.69) and US $3.43 (US$ 1.14 to US$8.53), respectively. The mean annual patient costs per person for PMTCT and ART in this evaluation will impact household income since PMTCT and ART services in Zimbabwe are supposed to be free.

Evidence on the spectrum of risk factors for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among front-line healthcare workers (HCWs) has not been well-described. While several studies evaluating the risk factors associated with SARS-CoV-2 infection among patient-facing and non-patient-facing front-line HCWs have been reported since the outbreak of the coronavirus disease in 2019 (COVID-19), and several more are still underway. There is, therefore, an immediate need for an ongoing, rigorous systematic review that continuously assesses the risk factors of SARS-CoV-2 infection among front-line HCWs. Here, we outline a protocol to serve as a guideline for conducting a living systematic review and meta-analysis to examine the burden of COVID-19 on front-line HCWs and identify risk factors for SARS-CoV-2 infection in patient-facing and non-patient-facing front-line HCWs. The protocol was developed and reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). The conduct of the proposed living systematic review and meta-analysis will primarily follow the principles recommended in the Centre for Reviews and Dissemination (CRD) guidance for undertaking systematic reviews in healthcare, and the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. The systematic literature searches will be performed using the EBSCOhost platform by searching the following databases within the platform: Academic search complete, health source: nursing/academic edition, CINAHL with full text, Embase, PubMed, MEDLINE, Science Direct databases, Google Scholar, and; also a search in the China National Knowledge Infrastructure and the World Health Organization library databases for relevant studies will be performed. The searches will include peer-reviewed articles, published in English and Mandarin language irrespective of publication year, evaluating the risk for testing positive for C0VID-19, the risk of developing symptoms associated with SARS-CoV-2 infection, or both, among front-line HCWs. The initial review period will consider articles published since the onset of COVID-19 disease to the present and then updated monthly. Review Manager (RevMan 5.3) will be used to pool the odds ratios or mean differences for individual risk factors where possible. Results will be presented as relative risks and 95% confidence intervals for dichotomous outcomes and mean differences, or standardised mean differences along with 95% confidence intervals, for continuous outcomes. The Newcastle-Ottawa Scale will be used to rate study quality, and the certainty of the evidence will be assessed by using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE). The results of the living systematic review and meta-analysis will be reported per the PRISMA guidelines. Though addressing the needs of front-line HCWs during the COVID-19 pandemic is a high priority, data to inform such initiatives are inadequate, particularly data on the risk factor disparities between patient-facing and non-patient-facing front-line HCWs. The proposed living systematic review and meta-analysis anticipate finding relevant studies reporting risk factors driving the SARS-CoV-2 infection rates among patient-facing and non-patient-facing front-line HCWs, thus providing subsidies for public health interventions and occupational health policies. The study results will be disseminated electronically, in print and through conference presentation, and key stakeholder meetings in the form of policy briefs.
