Background: The declaration of Coronavirus disease 2019 (COVID‐19) as a Public Health Emergency of International Concern (PHEIC) on 30 January 2020 required rapid implementation of early investigations to inform appropriate national and global public health actions.Methods: The suite of existing pandemic preparedness generic epidemiological early investigation protocols was rapidly adapted for COVID‐19, branded the ‘UNITY studies’ and promoted globally for the implementation of standardized and quality studies. Ten protocols were developed investigating household (HH) transmission, the first few cases (FFX), population seroprevalence (SEROPREV), health facilities transmission (n = 2), vaccine effectiveness (n = 2), pregnancy outcomes and transmission, school transmission, and surface contamination. Implementation was supported by WHO and its partners globally, with emphasis to support building surveillance and research capacities in low‐ and middle‐income countries (LMIC).Results: WHO generic protocols were rapidly developed and published on the WHO website, 5/10 protocols within the first 3 months of the response. As of 30 June 2021, 172 investigations were implemented by 97 countries, of which 62 (64%) were LMIC. The majority of countries implemented population seroprevalence (71 countries) and first few cases/household transmission (37 countries) studies.Conclusion: The widespread adoption of UNITY protocols across all WHO regions indicates that they addressed subnational and national needs to support local public health decision‐making to prevent and control the pandemic.

Universal health coverage (UHC) is defined as people having access to quality healthcare services (e.g., treatment, rehabilitation, and palliative care) they need, irrespective of their financial status. Access to quality healthcare services continues to be a challenge for many people in low- and middle-income countries (LMICs). The aim of this study was to conduct a scoping review to map out the health system strengthening strategies that can be used to attain universal health coverage in Africa. We conducted a scoping review and qualitatively synthesized existing evidence from studies carried out in Africa. We included studies that reported interventions to strengthen the health system, e.g., financial support, increasing work force, improving leadership capacity in health facilities, and developing and upgrading infrastructure of primary healthcare facilities. Outcome measures included health facility infrastructures, access to medicines, and sources of financial support. A total of 34 studies conducted met our inclusion criteria. Health financing and developing health infrastructure were the most reported interventions toward achieving UHC. Our results suggest that strengthening the health system, namely, through health financing, developing, and improving the health infrastructure, can play an important role in reaching UHC in the African context.

Immunization has made significant contribution to public health in the African Region, including elimination, eradication and control of life threatening diseases. Hospitalization due to vaccine preventable diseases has been drastically reduced due to introduction of new effective vaccines. However, optimizing the benefits of immunization by achieving high universal coverage has met with many challenges. The Regional immunization coverage, though raised from its low 57% in 2000 to 76% in 2015 has remained below expected target. Worse still, it has stagnated around 70% for a prolonged period. Cases of inequity in access to immunization service continue to exist in the region. This paper therefore explored the different challenges to immunization in the African Region. Some of the challenges it identifies and discusses include issues of sustainable funding and resources for immunization, vaccine stock-outs, and logistics. Others include data issues and laboratory infrastructure. The paper also attempted some possible solutions.

Hypertension is a leading cause of cardiovascular diseases and a growing public health problem in many developed and developing countries. However, population-based data to inform policy development are scarce in Rwanda. This nationally representative study aimed to determine population-based estimates of the prevalence and risk factors associated with hypertension in Rwanda. We conducted secondary epidemiological analysis of data collected from a cross-sectional population-based study to assess the risk factors for NCDs using the WHO STEPwise approach to Surveillance of non-communicable diseases (STEPS). Adjusted odds ratios at 95% confidence interval were used to establish association between hypertension, socio-demographic characteristics and health risk behaviors. Of the 7116 study participants, 62.8% were females and 38.2% were males. The mean age of study participants was 35.3 years (SD 12.5). The overall prevalence of hypertension was 15.3% (16.4% for males and 14.4% for females). Twenty two percent of hypertensive participants were previously diagnosed. A logistic regression model revealed that age (AOR: 8.02, 95% CI: 5.63–11.42, p < 0.001), living in semi-urban area (AOR: 1.30, 95% CI: 1.01–1.67, p = 0.040) alcohol consumption (AOR: 1.24, 95% CI: 1.05–1.44, p = 0.009) and, raised BMI (AOR: 3.93, 95% CI: 2.54–6.08, p < 0.001) were significantly associated with hypertension. The risk of having hypertension was 2 times higher among obese respondents (AOR: 3.93, 95% CI: 2.54–6.08, p-value < 0.001) compared to those with normal BMI (AOR: 1.74, 95% CI: 1.30–2.32, p-value < 0.001). Females (AOR: 0.75, 95% CI: 0.63–0.88, p < 0.001) and students (AOR: 0.45, 95% CI: 0.25–0.80, p = 0.007) were less likely to be hypertensive. The findings of this study indicate that the prevalence of hypertension is high in Rwanda, suggesting the need for prevention and control interventions aimed at decreasing the incidence taking into consideration the risk factors documented in this and other similar studies.

Background: Discussions on the use of digital health to advance health have continued to gain traction over the past decades. This is important considering the rising penetration of mobile phones and other digital technologies and the opportunity to leverage those digital and electronic health methods and innovations to accelerate Universal Health Coverage (UHC) and the health Sustainable Development Goals (SDGs). In Nigeria, however, the full benefits of digital technologies to strengthen the health systems are yet to be fully harnessed due to critical challenges in the sector. These challenges include but not limited to weak health systems governance, weak infrastructural investments, inadequate resources, weak human resource capacity, high cost of scaling-up and coordination issues among others. Lack of systems thinking, and design have significant impact on coordination of efforts and has resulted in the fragmentation and non-interoperability among various applications. To discuss these challenges and propose the way forward for rapid sustainable, scalable and cost-effective deployment of digital health in Nigeria, a digital health capacity development workshop was held in Abuja and across the six geo-political zones of Nigeria from 20th – 30th November 2019. This paper documents key conclusions and achievements at the workshop. Methods: The workshop was organized around eleven modules and seven thematic areas which explored the Nigerian digital health governance and coordinating mechanisms in view of its status, leadership, financing and deployment for effective service delivery. It was attended by over 100 participants from varied background including Ministries of Health, Ministries of Communications and Digital Economy, International Organizations, Operators, Civil Society, Academia and Private Sector Experts. Results: The workshop resolved that while digital health technologies offer profound opportunities to strengthen Nigerian health systems for UHC and the health SDGs, there should be a move from donor-driven pilot projects to robust, sustainable, cost-effective and nationally owned projects. This will involve a people-centered approach that should be demand-driven and not supply-driven to avoid wasting time on ineffective interventions, duplication of efforts and wastage of scarce health resources. Government ownership and leadership was identified as critical for sustainable financing and effective scale up of Digital Health projects in Nigeria. Conclusions: The DH capacity development workshop was a good forum to deliberate important issues regarding sustainable and cost-effective DH solutions that could be scaled to strengthen health service delivery in Nigeria. Insightful ideas for scaling DH in Nigeria and other related settings emanated from the workshop, necessitating the need for a focused government commitment and leadership in institutionalizing digital health in Nigeria.

Introduction: Cholera outbreaks remain persistent in the WHO African region, with an increased trend in recent years. This study analyses actual drivers of cholera including correlations with water, sanitation, and hygiene (WASH) indicators, and climate change trends. Methods: This was a cross-sectional descriptive and analytic study. Cholera data from 2000 to 2023 and data relating to cholera drivers were compiled and analysed through multi-level exploratory analysis. We cross-referenced several WASH indicators, and generated a similarity matrix to categorise countries or subnational units into groups using principal component analysis and K-means clustering. We integrated cholera outbreak data with WASH indicators and created a matrix of indicators relevant for analysing cholera burden. We conducted summary statistics, temporal visualisations, Geographic Information System (GIS) mapping, trend analysis and statistical tests for correlations to derive patterns and trends from the data, derive similarities and develop projections. Results: A total of 2 727 172 cases and 63 182 deaths were reported from 44 countries, representing 94% of the 47 countries in the region, from 2000 to 2023. The case fatality ratio of 2.3% is suggestive of issues in case management. A total of 684 outbreaks were reported, with the highest burdens in Nigeria and the Democratic Republic of the Congo. Median detection time to outbreak was 2 days, while median time for outbreak control was 92 days. Cholera incidence seemed higher in the period 2014 to 2023 than in the period before 2014. The study results confirmed correlations between WASH indicators and cholera outbreaks. Risks factors include drinking surface water, lacking soap and/or water, and open defaecation. Over 29% and 58.8% of the population lack access to basic water and basic sanitation, respectively. Conclusion: Insufficient access to WASH services remains the main predisposing factor for cholera in the WHO African region. Political leaders should invest more in access to WASH, strengthen multisectoral collaboration, and improve availability of needed tools to increase the likelihood of meeting cholera elimination goals by 2030.
