BACKGROUND In sub-Saharan Africa, underreporting of cases and deaths has been attributed to various factors including, weak disease surveillance, low health-seeking behaviour of flu like symptoms, and stigma of Covid-19. There is evidence that SARS-CoV-2 spread mimics transmission patterns of other countries across the world. Since the Covid-19 pandemic has changed the way research can be conducted and in light of restrictions on travel and risks to in-person data collection, innovative approaches to collecting data must be considered. Nearly 50% of Africa’s population is a unique mobile subscriber and it is one of the fastest growing smart-phone marketplaces in the world; hence, mobile phone platforms should be considered to monitor Covid-19 trends in the community. OBJECTIVE We demonstrate the use of digital contributor platforms to survey individuals about cases of flu-like symptoms and instances of unexplained deaths in Ethiopia, Kenya, Nigeria, Somalia, and Zimbabwe. METHODS Rapid cross-sectional survey of individuals with severe flu and pneumonia symptoms and unexplained deaths in Ethiopia, Kenya, Nigeria, Somalia and Zimbabwe RESULTS Using a non-health specific information platform, we found COVID-19 signals in five African countries, specifically: •Across countries, nearly half of the respondents (n=739) knew someone who had severe flu or pneumonia symptoms in recent months. •One in three respondents from Somalia and one in five from Zimbabwe respondents said they knew more than five people recently displaying flu and/or pneumonia symptoms. •In Somalia there were signals that a large number of people might be dying outside of health facilities, specifically in their homes or in IDP or refugee camps. CONCLUSIONS Existing digital contributor platforms with local networks are a non-traditional data source that can provide information from the community to supplement traditional government surveillance systems and academic surveys. We demonstrate that using these distributor networks to for community surveys can provide periodic information on rumours but could also be used to capture local sentiment to inform public health decision-making; for example, these insights could be useful to inform strategies to increase confidence in Covid19 vaccine. As Covid-19 continues to spread somewhat silently across sub-Saharan Africa, regional and national public health entities should consider expanding event-based surveillance sources to include these systems.

Abstract The COVID-19 pandemic has been a major threat to people and healthcare systems around the world. Each region of the world has had unique factors such as culture, demographics, socioeconomic and the political landscape that has either fueled or mitigated the severity of the pandemic. For example, the 2021 Indian Kumbh Mela festival fueled a devastating wave of the pandemic in India. Similarly, the pandemic in the United States has in part been fueled an epidemic of disinformation that led to a growing number of anti-vaxxers, and those who are opposed to COVID-19 prevention guidelines set by agencies like the Centers for Disease Control and Prevention. In Africa, burial practices in Liberia and the Democratic Republic of Congo once fueled the Ebola epidemic. Likewise, in the context of COVID-19, there are factors that are unique to Africa that may have either fueled or mitigated the severity of the pandemic. The anti-COVID-19 measures in many African countries significantly affected household income without commensurate deployment of palliative measures to cushion the effect. Fortunately, the pandemic has run a relatively milder course in sub-Saharan Africa—defying earlier devastating projections. Therefore, to be prepared for the next pandemic, African governments must involve critical stakeholders such as religious and traditional leaders, strengthen current disease surveillance systems and invest in systems that encourage private investments in local vaccine manufacturing.

AbstractSuicidal ideation is a critical risk for attempted suicide and eventual suicide. Little is known about suicidal ideation among rural adolescents in most sub-Saharan African countries. We aimed to estimate the 12-month prevalence of suicidal ideation and to describe some of the common and gender-specific associated factors among in-school adolescents in rural Ghana. We conducted a cross-sectional survey involving a random sample of 1101 in-school adolescents aged 10–19 years in a rural district in Eastern Ghana. The Suicidal Behavior Questionnaire-Revised was used to assess suicidal ideation. Overall, 25.1% participants (95% CI = 22.5–27.7), representing 28.3% females (95% CI = 24.7–32.2) and 21.5% males (95% CI = 18.0–25.2) reported suicidal ideation during the previous 12 months. Females who experienced personal and interpersonal adversities mainly outside the family context were likely to report suicidal ideation, while suicidal ideation among males was associated with conflict with parents. Regardless of gender, adolescents who reported exposure to a friend’s attempted suicide were about two times more likely to report suicidal ideation. The prevalence of suicidal ideation among adolescents in rural Ghana compares with in-school estimates from other countries within sub-Saharan Africa, but also underscores the need for targeted and universal prevention programmes and intervention efforts to mitigate the potential transition from suicidal ideations to suicidal attempts and eventual deaths by suicide among rural adolescents.

Objectives: Low and Middle-Income Countries are experiencing a fast-paced epidemiological rise in clusters of non-communicable diseases such as diabetes and cardiovascular disease, forming an imminent rise in multimorbidity. However, preventing multimorbidity has received little attention in LMICs, especially in Sub-Saharan African Countries. Methods: Narrative review which scoped the most recent evidence in LMICs about multimorbidity determinants and appropriated them for potential multimorbidity prevention strategies. Results: MMD in LMICs is affected by several determinants including increased age, female sex, environment, lower socio-economic status, obesity, and lifestyle behaviours, especially poor nutrition, and physical inactivity. Multimorbidity public health interventions in LMICs, especially in Sub-Saharan Africa are currently impeded by local and regional economic disparity, underdeveloped healthcare systems, and concurrent prevalence of communicable and non-communicable diseases. However, lifestyle interventions that are targeted towards preventing highly prevalent multimorbidity clusters, especially hypertension, diabetes, and cardiovascular disease, can provide early prevention of multimorbidity, especially within Sub-Saharan African countries with emerging economies and socio-economic disparity. Conclusion: Future public health initiatives should consider targeted lifestyle interventions and appropriate policies and guidelines in preventing multimorbidity in LMICs.

Abstract Background Malaria in pregnancy is a crucial public health concern due to the enormous risk it poses to maternal and newborn health. The World Health Organisation therefore recommends insecticide-treated net (ITN) for pregnant women. The world over, sub-Saharan Africa bears the highest prevalence of malaria and its associated complications. This study investigated the individual, community and society level factors associated with ITN use among pregnant women in sub-Saharan Africa. Methods The study was conducted with Demographic and Health Survey data of 21 sub-Saharan African countries. A total of 17,731 pregnant women who possessed ITN participated in the study. Descriptive computation of ITN use by survey country and socio-demographic characteristics was conducted. Further, five multi-level binary logistic regression models were fitted with MLwiN 3.05 package in STATA. The Markov Chain Monte Carlo (MCMC) estimation procedure was used in estimating the parameters whilst the Bayesian Deviance Information Criterion was used for the model fitness test. Results On average, 74.2% pregnant women in SSA used ITN. The highest prevalence of ITN use occurred in Mali (83.7%) whilst the least usage occurred in Namibia (7%). Women aged 30–34 were more likely to use ITN compared with those aged 45–49 [aOR = 1.14; Crl = 1.07–1.50]. Poorest women were less probable to use ITN relative to richest women [aOR = 0.79; Crl = 0.70–0.89]. Compared to women who did not want their pregnancies at all, women who wanted their pregnancies [aOR = 1.06; Crl = 1.04–1.19] were more probable to use ITN. Women in male-headed households had higher likelihood of ITN use compared to those from female-headed households [aOR = 1.28; Crl = 1.19–1.39]. On the whole, 38.1% variation in ITN use was attributable to societal level factors whilst 20.9% variation was attributable to community level factors. Conclusion The study has revealed that in addition to individual level factors, community and society level factors affect ITN use in SSA. In as much as the study points towards the need to incorporate community and societal variations in ITN interventions, active involvement of men can yield better outcome for ITN utilisation interventions in SSA.

Hiv Aids

HIV/AIDS and other sexually transmitted infections (STIs) continue to be among the greatest public health threats worldwide, especially in sub-Saharan Africa (SSA). Condom use remains an essential intervention to eradicate AIDS, and condom use is now higher than ever. However, free and subsidized condom funding is declining. Research on how to create healthy markets based on willingness to pay for condoms is critically important. This research has three primary aims: (1) willingness of free condom users in five African countries to pay for socially marketed condoms; (2) the relationship between specific population variables and condom brand marketing efforts and willingness to pay; and (3) potential opportunities to improve condom uptake. Nationally representative samples of at least 1200 respondents were collected in Kenya, Nigeria, South Africa, Zambia, and Zimbabwe. We collected data on a range of demographic factors, including condom use, sexual behavior, awareness of condom brands, and willingness to pay. We estimated multivariate linear regression models and found that free condom users are overwhelmingly willing to pay for condoms overall (over 90% in Nigeria) with variability by country. Free users were consistently less willing to pay for condoms if they had a positive identification with their free brand in Kenya and Zimbabwe, suggesting that condom branding is a critical strategy. Ability to pay was negatively correlated with willingness, but users who could not obtain free condoms were willing to pay for them in Kenya and Zimbabwe. In a landscape of declining donor funding, this research suggests opportunities to use scarce funds for important efforts such as campaigns to increase demand, branding of condoms, and coordination with commercial condom manufacturers to build a healthy total market approach for the product. Free condoms remain an important HIV/AIDS prevention tool. Building a robust market for paid condoms in SSA is a public health priority.

SummaryUnder-five mortality remains a major public health challenge in sub-Saharan Africa. Zimbabwe is one of the countries in the region that failed to achieve Millennium Developmental Goal 4 in 2015. The objective of this study was to examine the extent to which maternal health-seeking behaviour prior to and during pregnancy and post-delivery influences the likelihood of under-five mortality among Zimbabwean children. The study was cross-sectional and data were extracted from the 2010/11 Zimbabwe Demographic and Health Survey (ZDHS). The study sample comprised 5155 children who were born five years preceding the 2010/11 ZDHS to a sample of 4128 women of reproductive age (15–49 years). Cox Proportional Hazard regression modelling was used to examine the relationship between maternal health-seeking behaviour and under-five mortality. The results showed that maternal health-seeking behaviour factors are associated with the risk of dying during childhood. Children born to mothers who had ever used contraceptives (HR: 0.38, CI 0.28–0.51) had a lower risk of dying during childhood compared with children born to mothers who had never used any contraceptive method. The risk of under-five mortality among children who had a postnatal check-up within two months after birth (HR: 0.36, CI 0.23–0.56) was lower than that of children who did not receive postnatal care. Small birth size (HR: 1.70, CI 1.20–2.41) and higher birth order (2+) increased the risk of under-five mortality. Good maternal health-seeking behaviour practices at the three critical stages around childbirth have the potential to reduce under-five mortality. Therefore, public health programmes should focus on influencing health-seeking behaviour among women and removing obstacles to effective maternal health-seeking behaviour in Zimbabwe.

African Politics: A Very Short Introduction explores how politics is practised on the African continent, providing an overview of the different states and their systems. It considers the nature of the state in sub-Saharan Africa and why its state structures are generally weaker than elsewhere in the world. Exploring the historical and contemporary factors that account for Africa’s underdevelopment, it also analyses why some African countries suffer from high levels of political violence while others are spared. Unveiling the ways in which African state and society actually function beyond the formal institutional façade, this VSI discusses how external factors—both inherited and contemporary—act upon the continent.

The Impact

PurposeThe purpose of this study is to examine the impact of economic freedom on four key health indicators (namely, life expectancy, infant mortality rate, under-five mortality rate and neonatal mortality rate) by using a panel dataset of 34 sub-Saharan African countries from 2005 to 2016.Design/methodology/approachThe study obtains data from the World Development Indicators (WDI) of the World Bank and the Fraser Institute. It uses fixed effects regression to estimate the effect of economic freedom on health outcomes and attempts to resolve the endogeneity problems by using two-stage least squares regression (2SLS).FindingsThe results indicate a favourable impact of economic freedom on health outcomes. That is, higher levels of economic freedom reduce mortality rates and increase life expectancy in sub-Saharan Africa. All areas of economic freedom, except government size, have a significant and positive effect on health outcomes.Research limitations/implicationsThis study analyses the effect of economic freedom on health at a broad level. Country-specific studies at a disaggregated level may provide additional information about the impact of economic freedom on health outcomes. Also, this study does not control for some important variables such as education, income inequality and foreign aid due to data constraints.Practical implicationsThe findings suggest that sub-Saharan African countries should focus on enhancing the quality of economic institutions to improve their health outcomes. This may include policy reforms that support a robust legal system, protect property rights, promote free trade and stabilise the macroeconomic environment. In addition, policies that raise urbanisation, increase immunisation and lower the incidence of HIV are likely to produce a substantial improvement in health outcomes.Originality/valueExtant economic freedom-health literature does not focus on endogeneity problems. This study uses instrumental variables regression to deal with endogeneity. Also, this is one of the first attempts to empirically investigate the relationship between economic freedom and health in the case of sub-Saharan Africa.

A major focus of international health and development goals is the reduction of mortality rates in children under 5 years of age. Achieving this requires understanding the drivers of mortality and how they vary geographically to facilitate the targeting and prioritisation of appropriate interventions. Much of our knowledge on the causes of, and trends in, childhood mortality come from longitudinal demographic surveillance sites, with a renewed focus recently on the establishment and growth of networks of sites from which standardised outputs can facilitate broader understanding of processes. To ensure that the collective outputs from surveillance sites can be used to derive a comprehensive understanding and monitoring system for driving policy on tackling childhood mortality, confidence is needed that existing and planned networks of sites are providing a reliable and representative picture of the geographical variation in factors associated with mortality. Here, we assembled subnational data on childhood mortality as well as key factors known to be associated with it from household surveys in 27 sub-Saharan African countries. We then mapped the locations of existing longitudinal demographic surveillance sites to assess the extent of current coverage of the range of factors, identifying where gaps exist. The results highlight regions with unique combinations of factors associated with childhood mortality that are poorly represented by the current distribution of sites, such as southern Mali, central Nigeria and southern Zambia. Finally, we determined where the establishment of new surveillance systems could improve coverage.

Despite the fact that the African continent is positioned as one of the fastest growing economies in the world (especially the sub-region of sub-Saharan Africa), the lack of industrialization and the use of modern technologies continues to be a brake on the development of the economies of African countries, which largely depend on agriculture and exports of raw goods that have a relatively low added value and account for more than 80% of their exports. This has a negative impact not only on the economic development of the region, but also on per capita incomes of the population. This article assesses the existing economic potential of African countries, which is one of the most important factors for overcoming economic backwardness, achieving the goals of sustainable development, raising the standard of living of the population and changing the status of SSA countries in the world economic system. It is shown that it is important for African states to attract new technologies and innovative products to the industrial and agricultural sectors, since knowledge and innovations are the locomotive of economic growth and are one of the most important factors in the reconstruction and modernization of their economies.
