Severe Acute Respiratory Syndrome Coronavirus 2 Infection and Pregnancy in Sub-Saharan Africa: A 6-Country Retrospective Cohort Analysis.

BACKGROUND: Few data are available on COVID-19 outcomes among pregnant women in sub-Saharan Africa (SSA), where high-risk comorbidities are prevalent. We investigated the impact of pregnancy on SARS-CoV-2 infection and of SARS-CoV-2 infection on pregnancy to generate evidence for health policy and clinical practice. METHODS: We conducted a 6-country retrospective cohort study among hospitalized women of childbearing age between 1 March 2020 and 31 March 2021. Exposures were (1) pregnancy and (2) a positive SARS-CoV-2 RT-PCR test. The primary outcome for both analyses was intensive care unit (ICU) admission. Secondary outcomes included supplemental oxygen requirement, mechanical ventilation, adverse birth outcomes, and in-hospital mortality. We used log-binomial regression to estimate the effect between pregnancy and SARS-CoV-2 infection. Factors associated with mortality were evaluated using competing-risk proportional subdistribution hazards models. RESULTS: Our analyses included 1315 hospitalized women: 510 pregnant women with SARS-CoV-2, 403 nonpregnant women with SARS-CoV-2, and 402 pregnant women without SARS-CoV-2 infection. Among women with SARS-CoV-2 infection, pregnancy was associated with increased risk for ICU admission (adjusted risk ratio [aRR]: 2.38; 95% CI: 1.42-4.01), oxygen supplementation (aRR: 1.86; 95% CI: 1.44-2.42), and hazard of in-hospital death (adjusted sub-hazard ratio [aSHR]: 2.00; 95% CI: 1.08-3.70). Among pregnant women, SARS-CoV-2 infection increased the risk of ICU admission (aRR: 2.0; 95% CI: 1.20-3.35), oxygen supplementation (aRR: 1.57; 95% CI: 1.17-2.11), and hazard of in-hospital death (aSHR: 5.03; 95% CI: 1.79-14.13). CONCLUSIONS: Among hospitalized women in SSA, both SARS-CoV-2 infection and pregnancy independently increased risks of ICU admission, oxygen supplementation, and death. These data support international recommendations to prioritize COVID-19 vaccination among pregnant women.

Assessment of Clinical Outcomes Among Children and Adolescents Hospitalized With COVID-19 in 6 Sub-Saharan African Countries.

IMPORTANCE: Little is known about COVID-19 outcomes among children and adolescents in sub-Saharan Africa, where preexisting comorbidities are prevalent. OBJECTIVE: To assess the clinical outcomes and factors associated with outcomes among children and adolescents hospitalized with COVID-19 in 6 countries in sub-Saharan Africa. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was a retrospective record review of data from 25 hospitals in the Democratic Republic of the Congo, Ghana, Kenya, Nigeria, South Africa, and Uganda from March 1 to December 31, 2020, and included 469 hospitalized patients aged 0 to 19 years with SARS-CoV-2 infection. EXPOSURES: Age, sex, preexisting comorbidities, and region of residence. MAIN OUTCOMES AND MEASURES: An ordinal primary outcome scale was used comprising 5 categories: (1) hospitalization without oxygen supplementation, (2) hospitalization with oxygen supplementation, (3) ICU admission, (4) invasive mechanical ventilation, and (5) death. The secondary outcome was length of hospital stay. RESULTS: Among 469 hospitalized children and adolescents, the median age was 5.9 years (IQR, 1.6-11.1 years); 245 patients (52.4%) were male, and 115 (24.5%) had comorbidities. A total of 39 patients (8.3%) were from central Africa, 172 (36.7%) from eastern Africa, 208 (44.3%) from southern Africa, and 50 (10.7%) from western Africa. Eighteen patients had suspected (n = 6) or confirmed (n = 12) multisystem inflammatory syndrome in children. Thirty-nine patients (8.3%) died, including 22 of 69 patients (31.9%) who required intensive care unit admission and 4 of 18 patients (22.2%) with suspected or confirmed multisystem inflammatory syndrome in children. Among 468 patients, 418 (89.3%) were discharged, and 16 (3.4%) remained hospitalized. The likelihood of outcomes with higher vs lower severity among children younger than 1 year expressed as adjusted odds ratio (aOR) was 4.89 (95% CI, 1.44-16.61) times higher than that of adolescents aged 15 to 19 years. The presence of hypertension (aOR, 5.91; 95% CI, 1.89-18.50), chronic lung disease (aOR, 2.97; 95% CI, 1.65-5.37), or a hematological disorder (aOR, 3.10; 95% CI, 1.04-9.24) was associated with severe outcomes. Age younger than 1 year (adjusted subdistribution hazard ratio [asHR], 0.48; 95% CI, 0.27-0.87), the presence of 1 comorbidity (asHR, 0.54; 95% CI, 0.40-0.72), and the presence of 2 or more comorbidities (asHR, 0.26; 95% CI, 0.18-0.38) were associated with reduced rates of hospital discharge. CONCLUSIONS AND RELEVANCE: In this cohort study of children and adolescents hospitalized with COVID-19 in sub-Saharan Africa, high rates of morbidity and mortality were observed among infants and patients with noncommunicable disease comorbidities, suggesting that COVID-19 vaccination and therapeutic interventions are needed for young populations in this region.

The Critical Need for Pooled Data on Coronavirus Disease 2019 in African Children: An AFREhealth Call for Action Through Multicountry Research Collaboration.

Globally, there are prevailing knowledge gaps in the epidemiology, clinical manifestations, and outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among children and adolescents; and these gaps are especially wide in African countries. The availability of robust age-disaggregated data is a critical first step in improving knowledge on disease burden and manifestations of coronavirus disease 2019 (COVID-19) among children. Furthermore, it is essential to improve understanding of SARS-CoV-2 interactions with comorbidities and coinfections such as human immunodeficiency virus (HIV), tuberculosis, malaria, sickle cell disease, and malnutrition, which are highly prevalent among children in sub-Saharan Africa. The African Forum for Research and Education in Health (AFREhealth) COVID-19 Research Collaboration on Children and Adolescents is conducting studies across Western, Central, Eastern, and Southern Africa to address existing knowledge gaps. This consortium is expected to generate key evidence to inform clinical practice and public health policy-making for COVID-19 while concurrently addressing other major diseases affecting children in African countries.

Knowledge, preparedness, and attitude towards COVID-19 among health profession students in Sub-Saharan Africa: A cross-sectional survey.

Objective: We assessed the knowledge, preparedness, and attitude of health profession students towards COVID-19 outbreak in Sub-Saharan Africa. Methods: This cross-sectional study used convenience sampling to recruit participants from institutions under African Forum for Research and Education in Health (AFREhealth). The survey was developed in QuestionPro software covering the participants' socio-demographic characteristics, knowledge, attitude, and preparedness towards the COVID-19 outbreak. Data were analysed and the association between variables was tested. Results: The mean age of the 336 students was 25•75 (±7•88) years. Most (99•7%) knew the cause of COVID-19 which could be transmitted via droplets (97•3%). Several participants vowed to adhere to preventive measures (92•3%) and claimed their curriculum equipped them with skills addressing infectious disease outbreaks (63•6%). Nursing students were better prepared than other students (p=0•001). Students from West African regions were more prepared (p=0•001) and aware they could contract COVID-19 if they cared for infected persons (p=0•001). Conclusion: Students are knowledgeable about COVID-19, adequately prepared to handle epidemics, have a positive attitude towards infection prevention, and their training institutions and government have taken adequate measures to address the COVID-19 outbreak.

European collaborations on medicine and vaccine procurement.

To ensure equitable access to medicines and vaccines, organizational efforts and purchase volumes have been pooled in joint procurements and negotiations for decades in some regions of the world, as well as globally through supranational procurement mechanisms. In Europe, countries started to collaborate on procurement and negotiations recently when it became increasingly difficult to ensure access to high-priced medicines, even in high-income countries. Two European country collaborations (the Nordic Pharmaceutical Forum and the Baltic Procurement Initiative) have successfully concluded at least one joint tender process for medicines and vaccines and the Beneluxa Initiative has concluded its first successful joint price negotiation. This article describes the experiences of these country collaborations. Challenges observed included: legal barriers; institutional and organizational differences between health-care systems in member countries; and the risk that suppliers will be reluctant to cooperate with country collaborations. Although these collaborations helped improve access to medicines and vaccines for the countries involved, in situations such as a global health crisis, larger-scale, more-inclusive initiatives are needed. In the current coronavirus disease 2019 (COVID-19) pandemic, COVID-19 Vaccines Global Access (COVAX) initiative established a global procurement mechanism to ensure the equitable distribution of COVID-19 vaccines globally. Despite differences in organization and scale, the European country collaborations and COVAX have some similarities: (i) their success depends on the increased purchasing power associated with pooled order volumes; (ii) expert knowledge and previous procurement experience is pooled; (iii) they perform other collaborative activities that go beyond procurement alone; and (iv) they actively involve external partners and stakeholders.

Depuis des décennies, certaines régions du monde ont uni leurs efforts pour s'organiser, négocier et effectuer des achats groupés de grandes quantités afin d'assurer un accès équitable aux médicaments et vaccins. Des mécanismes d'acquisition supranationaux ont fait de même à l'échelle planétaire. En Europe, des États ont récemment commencé à collaborer en matière d'achat et de négociation lorsqu'il est devenu de plus en plus difficile de garantir l'accès à des médicaments coûteux, y compris dans les pays à haut revenu. Deux collaborations entre pays européens (le Forum pharmaceutique nordique et l'Initiative d'acquisition de la Baltique) ont mené à bien au moins un processus d'offre conjoint pour des médicaments et vaccins, tandis que l'Initiative Beneluxa a conclu sa première négociation tarifaire conjointe. Cet article décrit les expériences liées à ces collaborations entre nations. Plusieurs défis se sont posés, notamment des obstacles juridiques; des différences institutionnelles et organisationnelles entre les systèmes de santé des États membres; et enfin, le risque que les fournisseurs soient peu enclins à accepter ces collaborations entre pays. Bien que ces collaborations aient amélioré l'accès aux médicaments et vaccins pour les pays impliqués, des initiatives plus globales et à plus grande échelle sont nécessaires dans des situations telles qu'une crise sanitaire mondiale. Durant l'actuelle pandémie de maladie à coronavirus 2019 (COVID-19), l'initiative COVAX (COVID-19 Vaccines Global Access) a abouti à un dispositif d'approvisionnement mondial pour veiller à distribuer équitablement des vaccins contre la COVID-19 dans le monde. Malgré des variations d'organisation et d'échelle, les collaborations entre États européens partagent des similitudes avec le COVAX: (i) le succès de ces deux démarches dépend d'un accroissement du pouvoir d'achat combiné à des volumes de commande groupés; (ii) elles mettent en commun les connaissances approfondies et expériences passées; (iii) elles mènent d'autres activités collectives qui dépassent le simple cadre de l'acquisition; et enfin, (iv) elles impliquent activement une série d'intervenants et de partenaires externes.

Para garantizar un acceso equitativo a los medicamentos y las vacunas, los esfuerzos organizativos y los volúmenes de compra se han unido en adquisiciones y negociaciones conjuntas durante décadas en algunas regiones del mundo, así como a nivel mundial a través de mecanismos de adquisición supranacionales. En Europa, los países empezaron a colaborar en las adquisiciones y negociaciones recientemente, cuando se hizo cada vez más difícil garantizar el acceso a los medicamentos con precios altos, incluso en los países de renta alta. Dos colaboraciones de países europeos (el Foro Farmacéutico Nórdico y la Iniciativa de Adquisición del Báltico) han concluido con éxito al menos un proceso de licitación conjunta de medicamentos y vacunas, y la Iniciativa Beneluxa ha concluido con éxito su primera negociación conjunta de precios. Este artículo describe las experiencias de estas colaboraciones entre países. Entre los retos observados se encuentran: las barreras legales, las diferencias institucionales y organizativas entre los sistemas sanitarios de los países miembros y el riesgo de que los proveedores se muestren reacios a cooperar con las colaboraciones entre países. Aunque estas colaboraciones ayudaron a mejorar el acceso a los medicamentos y las vacunas para los países implicados, en situaciones como una crisis sanitaria mundial, se necesitan iniciativas a mayor escala y más inclusivas. En la actual pandemia de la enfermedad por coronavirus (COVID-19), la iniciativa Acceso global a las vacunas de la COVID-19 (COVAX, por sus siglas en inglés) estableció un mecanismo de adquisición mundial para garantizar la distribución equitativa de las vacunas contra la COVID-19 en todo el mundo. A pesar de las diferencias de organización y escala, las colaboraciones de los países europeos y COVAX tienen algunas similitudes: i) su éxito depende del mayor poder adquisitivo asociado a los volúmenes de pedidos mancomunados; ii) se ponen en común los conocimientos de los expertos y la experiencia previa en materia de adquisiciones; iii) realizan otras actividades de colaboración que van más allá de la mera adquisición; e iv) implican activamente a socios y partes interesadas externas.

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

Most African countries have recorded relatively lower COVID-19 burdens than Western countries. This has been attributed to early and strong political commitment and robust implementation of public health measures, such as nationwide lockdowns, travel restrictions, face mask wearing, testing, contact tracing, and isolation, along with community education and engagement. Other factors include the younger population age strata and hypothesized but yet-to-be confirmed partially protective cross-immunity from parasitic diseases and/or other circulating coronaviruses. However, the true burden may also be underestimated due to operational and resource issues for COVID-19 case identification and reporting. In this perspective article, we discuss selected best practices and challenges with COVID-19 contact tracing in Nigeria, Rwanda, South Africa, and Uganda. Best practices from these country case studies include sustained, multi-platform public communications; leveraging of technology innovations; applied public health expertise; deployment of community health workers; and robust community engagement. Challenges include an overwhelming workload of contact tracing and case detection for healthcare workers, misinformation and stigma, and poorly sustained adherence to isolation and quarantine. Important lessons learned include the need for decentralization of contact tracing to the lowest geographic levels of surveillance, rigorous use of data and technology to improve decision-making, and sustainment of both community sensitization and political commitment. Further research is needed to understand the role and importance of contact tracing in controlling community transmission dynamics in African countries, including among children. Also, implementation science will be critically needed to evaluate innovative, accessible, and cost-effective digital solutions to accommodate the contact tracing workload.

From Easing Lockdowns to Scaling Up Community-based Coronavirus Disease 2019 Screening, Testing, and Contact Tracing in Africa-Shared Approaches, Innovations, and Challenges to Minimize Morbidity and Mortality.

The arrival of coronavirus disease 2019 (COVID-19) on the African continent resulted in a range of lockdown measures that curtailed the spread of the infection but caused economic hardship. African countries now face difficult choices regarding easing of lockdowns and sustaining effective public health control measures and surveillance. Pandemic control will require efficient community screening, testing, and contact tracing; behavioral change interventions; adequate resources; and well-supported, community-based teams of trained, protected personnel. We discuss COVID-19 control approaches in selected African countries and the need for shared, affordable, innovative methods to overcome challenges and minimize mortality. This crisis presents a unique opportunity to align COVID-19 services with those already in place for human immunodeficiency virus, tuberculosis, malaria, and non communicable diseases through mobilization of Africa's interprofessional healthcare workforce. By addressing the challenges, the detrimental effect of the COVID-19 pandemic on African citizens can be minimized.

Access considerations for a COVID-19 vaccine for South Africa.

The novel coronavirus (COVID-19) pandemic is a defining point in human history, having far-reaching effects on all aspects of human life. In the race to find a vaccine, governments need to work collectively to ensure that any life-saving interventions are accessible and affordable to populations across the globe. This pandemic has created an opportunity for international cooperation in working on transparency issues both in terms of sharing manufacturing details to make devices for the diagnosis and treatment of COVID-19 and in terms of clinical trials for therapies that could prove to be effective against the disease.

Artemisia Spp. Derivatives for COVID-19 Treatment: Anecdotal Use, Political Hype, Treatment Potential, Challenges, and Road Map to Randomized Clinical Trials.

The world is currently facing a novel COVID-19 pandemic caused by SARS-CoV-2 that, as of July 12, 2020, has caused a reported 12,322,395 cases and 556,335 deaths. To date, only two treatments, remdesivir and dexamethasone, have demonstrated clinical efficacy through randomized controlled trials (RCTs) in seriously ill patients. The search for new or repurposed drugs for treatment of COVID-19 continues. We have witnessed anecdotal use of herbal medicines, including Artemisia spp. extracts, in low-income countries, and exaggerated claims of their efficacies that are not evidence based, with subsequent political controversy. These events highlight the urgent need for further research on herbal compounds to evaluate efficacy through RCTs, and, when efficacious compounds are identified, to establish the active ingredients, develop formulations and dosing, and define pharmacokinetics, toxicology, and safety to enable drug development. Derivatives from the herb Artemisia annua have been used as traditional medicine over centuries for the treatment of fevers, malaria, and respiratory tract infections. We review the bioactive compounds, pharmacological and immunological effects, and traditional uses for Artemisia spp. derivatives, and discuss the challenges and controversies surrounding current efforts and the scientific road map to advance them to prevent or treat COVID-19.

Chloroquine and Hydroxychloroquine for the Prevention or Treatment of COVID-19 in Africa: Caution for Inappropriate Off-label Use in Healthcare Settings.

The novel severe acute respiratory syndrome-coronavirus-2 pandemic has spread to Africa, where nearly all countries have reported laboratory-confirmed cases of novel coronavirus disease (COVID-19). Although there are ongoing clinical trials of repurposed and investigational antiviral and immune-based therapies, there are as yet no scientifically proven, clinically effective pharmacological treatments for COVID-19. Among the repurposed drugs, the commonly used antimalarials chloroquine (CQ) and hydroxychloroquine (HCQ) have become the focus of global scientific, media, and political attention despite a lack of randomized clinical trials supporting their efficacy. Chloroquine has been used worldwide for about 75 years and is listed by the WHO as an essential medicine to treat malaria. Hydroxychloroquine is mainly used as a therapy for autoimmune diseases. However, the efficacy and safety of CQ/HCQ for the treatment of COVID-19 remains to be defined. Indiscriminate promotion and widespread use of CQ/HCQ have led to extensive shortages, self-treatment, and fatal overdoses. Shortages and increased market prices leave all countries vulnerable to substandard and falsified medical products, and safety issues are especially concerning for Africa because of its healthcare system limitations. Much needed in Africa is a cross-continental collaborative network for coordinated production, distribution, and post-marketing surveillance aligned to low-cost distribution of any approved COVID-19 drug; this would ideally be piggybacked on existing global aid efforts. Meanwhile, African countries should strongly consider implementing prescription monitoring schemes to ensure that any off-label CQ/HCQ use is appropriate and beneficial during this pandemic.
