Perspectives on the Regional Strategy for Implementation of National Action Plans on Antimicrobial Resistance in the WHO African Region.

Background: The WHO Regional Office for Africa developed a Member States (MS)-endorsed regional strategy to fast-track the implementation of MS' national action plans (NAP) on Antimicrobial resistance (AMR). This study explored the perspectives of AMR's national focal points in MS on the implementation of the priority interventions of the regional strategy in their countries. Methods: An online survey consisting of ratings and discussions covering the implementation of the six priority interventions was conducted. Sums of the scores per priority intervention were obtained, and their percentage to the total possible scores were calculated to categorize the implementation as inadequate (0-25%), basic (26-50%), intermediate (51-75%), or advanced (76-100%). Results: Thirty-six of the forty-seven national AMR focal points responded to the survey between 12 November 2023 and 8 January 2024. The implementations were rated as 37-62% (basic-to-intermediate), with the multisectoral coordination and collaboration committee receiving the highest overall rating (62%, 421/684), while the promotion of sustainable investment for the NAP on AMR received the least overall rating (37%, 257/700). The focal points mainly recommended awareness campaigns, capacity building, and regulations and guidelines to improve the implementation of the AMR strategy. Conclusions: The survey revealed a need to enhance awareness campaigns, support the establishment and functioning of AMR evaluation and monitoring systems, and build the capacity of AMR staff with cost-benefit analysis and budgeting skills. It also showed the necessity to improve awareness and conduct education on AMR, streamline evidence generation through One Health Surveillance systems, integrate initiatives to reduce hospital-acquired infections in the antimicrobial stewardship programs, and enhance regulations and guidelines to optimize the use of antimicrobials.

Surveillance of Antimicrobial Resistance in the ECOWAS Region: Setting the Scene for Critical Interventions Needed.

Antimicrobial resistance poses a significant challenge to public health globally, leading to increased morbidity and mortality. AMR surveillance involves the systematic collection, analysis, and interpretation of data on the occurrence and distribution of AMR in humans, animals, and the environment for action. The West African Health Organization, part of the Economic Community of West African States (ECOWAS), is committed to addressing AMR in the region. This paper examines the status of AMR surveillance in ECOWAS countries using available WHO data from the TrACSS survey and GLASS enrollments. The analysis reveals that while progress has been made, significant challenges remain. Twelve of the fifteen ECOWAS countries are enrolled in GLASS, and ten have developed national action plans (NAPs) for AMR. However, there is a need to ensure all countries fully implement their NAPs, continue reporting to GLASS, and use the data for evidence-based actions and decision making. Surveillance systems for AMR and antimicrobial consumption/use vary across countries with some demonstrating limited capacity. All countries, except Cabo Verde, reported having a reference laboratory for AMR testing. Strengthening laboratory capabilities, data management and use, and multisectoral coordination are crucial for effective AMR surveillance and response. Based on the findings and the regional context, it is essential to prioritize capacity building, data utilization, and the adoption of standardized guidelines for AMR surveillance. Collaboration among ECOWAS countries, the WAHO, and international partners is essential to address AMR comprehensively. Ensuring a consistent supply of essential antimicrobial medications and reagents is vital.

Antimicrobial Resistance in the WHO African Region: A Systematic Literature Review 2016-2020.

Antimicrobial resistance (AMR) is a significant global public health threat. This review presents the most recent in-depth review of the situation of the main AMR types in relation to the most commonly prescribed antibiotics in the World Health Organization (WHO) African Region. Underlying genes of resistance have been analyzed where possible. A search to capture published research data on AMR from articles published between 2016 and 2020 was done using PubMed and Google Scholar, with rigorous inclusion/exclusion criteria. Out of 48003 articles, only 167 were included. Among the tested gram-negative bacteria species, Klebsiella spp. remain the most tested, and generally the most resistant. The highest overall phenotypic resistance for imipenem was reported in E. coli, whereas for meropenem, E. coli and Haemophilus spp. showed an equal resistance proportion at 2.5%. For gram-positive bacteria, Streptococcus pneumoniae displayed high resistance percentages to trimethoprim/sulfamethoxazole (64.3%), oxacillin (32.2%), penicillin (23.2%), and tetracycline (28.3%), whereas Staphylococcus aureus contributed to 22.8% and 10% resistance to penicillin and oxacillin, respectively. This review shows that AMR remains a major public health threat. The present findings will help public health decision-makers in developing efficient preventive strategies and adequate policies for antibiotic stewardship and surveillance in line with the global action plan for AMR.

Education and Awareness on Antimicrobial Resistance in the WHO African Region: A Systematic Review.

This review documents the status of AMR education and awareness in the WHO African region, as well as specific initiatives by its member states in implementing education and awareness interventions, as a strategic objective of the Global Action Plan on AMR, i.e., improve knowledge and understanding on AMR through effective communication, education, and training. A systematic search was conducted in Google Scholar, PubMed, and African Journals Online Library according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, for articles published in English. Retrieval and screening of articles was performed using a structured search protocol following a pre-set inclusion/exclusion criterion. Eighty-five published articles reporting 92 different studies from 19 Member States met inclusion criteria and were included in the final qualitative synthesis. Nigeria (21) and Ethiopia (16) had most of the studies, while the rest were distributed across the remaining 17 Member States. The majority of the articles were on knowledge, attitude, and practices with regard to AMR and antimicrobial use and most of them documented a general lack and suboptimal knowledge, poor attitude and practices, and widespread self-medication. This review shows low levels of knowledge of AMR coupled with extensive misuse of antimicrobial medicines by different target audiences. These findings underscore the urgent need for enhanced and context-specific educational and positive behavioural change interventions.

Monitoring progress on Antimicrobial Resistance (AMR) response in the World Health Organization African region: Insights from the Tracking AMR Country Self-Assessment Survey (TrACSS) 2021 results for the human health sector.

Antimicrobial resistance (AMR) is a major 21st century global health challenge. The WHO African Region Member States committed to develop and implement multisectoral national action plans (NAPs) that address AMR, in line with the Global Action Plan on AMR (GAP). The aim of this paper is to present the progress of AMR response in the WHO African Region based on the annual Tracking AMR Country Self-Assessment Survey (TrACSS), with a focus on human health indicators. This was a secondary data analysis of responses from forty-one countries that participated in the 2021 TrACSS. Of the 41 countries that responded to the 2021 TrACSS, 35(85%) have developed NAPs. Fifteen 15(37%) of countries have functional AMR multisector working groups. 55% (21/41) of countries are collating data nationally on AMR surveillance. Forty nine percent of countries conducted small-scale AMR awareness campaigns and 53% (21/41) covered AMR in some pre- and in-service training for human health workers. While 83% of countries reported having laws and regulations on the prescription and sale of antimicrobials, only 32% (13/41) have national systems for monitoring antimicrobial use. Twenty-three (58%, 23/41) reported having Infection Prevention and Control (IPC) programs at select health facilities. Countries have developed and are implementing AMR NAPs. Gaps still exist across key indicators monitored through TrACSS. Effective AMR response requires established functional multisectoral governance mechanisms in the One Health approach; political commitment, sustainable funding, and clear monitoring and reporting is critical.

Global Antimicrobial Resistance and Use Surveillance System on the African continent: Early implementation 2017-2019.

Background: Antimicrobial resistance (AMR) is becoming a critical public health issue globally. The World Health Organization launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) to support the strengthening of the AMR evidence base. Objective: The article describes the evolution of national AMR surveillance systems and AMR data reporting of countries in the African continent between 2017 and 2019, and the constraints, perceived impact and value of the participation in GLASS. Methods: Data on implementation of national surveillance systems and AMR rates were submitted to GLASS between 2017 and 2019 and summarised though descriptive statistics. The information on constraints and perceived impact and value in GLASS participation was collected though a set of questionnaires. Results: Between 2017 and 2019, Egypt, Ethiopia, Madagascar, Malawi, Mali, Mozambique, Nigeria, South Africa, Sudan, Tunisia, Uganda and Zambia submitted data to GLASS. The main constraints listed are linked to scarce laboratory capacity and capability, limited staffing, budget issues, and data management. Moreover, while the data are not yet nationally representative, high resistance rates were reported to commonly-used antibiotics, as the emerging resistance to last treatment options. Conclusion: Despite the limitations, more and more countries in the African continent are working towards reaching a status that will enable them to report AMR data in a complete and systematic manner. Future improvements involve the expansion of routine surveillance capacity for several countries and the implementation of surveys that allow to effectively define the magnitude of AMR in the continent.

National action plan on antimicrobial resistance: An evaluation of implementation in the World Health Organization Africa region.

In line with global instruments, within the last five years, two-thirds of all countries in the WHO Africa Region (WHO AFR) have developed a National Action Plan (NAP) on Antimicrobial Resistance (AMR). We sought to evaluate progress made across the countries implementing NAP for effective response to AMR. A semi-structured survey tool was administered to obtain information from national focal persons on the implementation of strategic elements of NAP on AMR. This was followed by a Lessons Learnt Workshop in June 2019 at Douala, Cameroon, where focal persons made presentations on the country's progress. Later, a desktop review of the LLW report and other key documents was conducted. Countries in WHO AFR that have set up a national surveillance system and are enrolled into the WHO global antimicrobial resistance surveillance system have progressively increased to 30 (of 47 countries), of which 15 are already submitting surveillance data. Of the 20 countries at the Lessons Learnt Workshop, 14 have infection prevention and control (IPC) policies and functional healthcare facility IPC programs, 15 participate in the commemoration of the annual world hand hygiene days. Although almost all countries surveyed have national standard treatment guidelines, only five have incorporated the WHO AWaRe classification into the national essential medicines list. Fourteen of 20 countries have established an active/functional national secretariat/coordinating center for AMR. Discernible progress is being made on the implementation of NAP in WHO AFR region. Gaps identified in the strategic elements of action plans need to be filled for effective AMR control.

Preventing and managing antimicrobial resistance in the African region: A scoping review protocol.

INTRODUCTION: Antimicrobial resistance (AMR) constitutes a significant threat to global health and food security, typically associated with high morbidity and mortality rate. The high burden of infectious diseases coupled with the weak health systems in most countries of Africa magnifies the risk of increasing AMR and its consequences thereof. This scoping review will be aimed at mapping the evidence on interventions used to prevent and manage antimicrobial resistance in Africa, guided by the "One Health" concept. METHODS: We will consider interventions targeting multiple sectors such as health care systems, the agricultural and veterinary sectors. The outcomes to be considered include reduction of AMR decreased morbidity and mortality due to infectious diseases, increased awareness for rational use of antimicrobials and reduced antibiotic consumption. We will include all types of studies regardless of study designs conducted within the context of the WHO African region. Studies will be excluded if they are not conducted in Africa and if they are literature reviews, only describing the concept of AMR without mentioning interventions. We will include studies identified through a comprehensive search of peer-reviewed and grey literature databases. In addition, we will search the reference lists of included studies and relevant reviews. Finally, we plan to do a citation search for included studies. Findings of this review will be narratively synthesized.

Enhancing laboratory capacity during Ebola virus disease (EVD) heightened surveillance in Liberia: lessons learned and recommendations.

INTRODUCTION: Following a declaration by the World Health Organization that Liberia had successfully interrupted Ebola virus transmission on May 9th, 2015; the country entered a period of enhanced surveillance. The number of cases had significantly reduced prior to the declaration, leading to closure of eight out of eleven Ebola testing laboratories. Enhanced surveillance led to an abrupt increase in demand for laboratory services. We report interventions, achievements, lessons learned and recommendations drawn from enhancing laboratory capacity. METHODS: Using archived data, we reported before and after interventions that aimed at increasing laboratory capacity. Laboratory capacity was defined by number of laboratories with Ebola Virus Disease (EVD) testing capacity, number of competent staff, number of specimens tested, specimen backlog, daily and surge testing capacity, and turnaround time. Using Stata 14 (Stata Corporation, College Station, TX, USA), medians and trends were reported for all continuous variables. RESULTS: Between May and December 2015, interventions including recruitment and training of eight staff, establishment of one EVD laboratory facility, implementation of ten Ebola GeneXpert diagnostic platforms, and establishment of working shifts yielded an 8-fold increase in number of specimens tested, a reduction in specimens backlog to zero, and restoration of turn-around time to 24 hours. This enabled a more efficient surveillance system that facilitated timely detection and containment of two EVD clusters observed thereafter. CONCLUSION: Effective enhancement of laboratory services during high demand periods requires a combination of context-specific interventions. Building and ensuring sustainability of local capacity is an integral part of effective surveillance and disease outbreak response efforts.

Spinocerebellar ataxia type 2 (SCA2): clinical features and genetic analysis.

Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant neurodegenerative disease that results from the expansion of an unstable trinucleotide CAG repeat encoding for a polyglutamine tract. In normal individuals, alleles contain between 14 and 31 CAG repeats, whereas the pathological alleles have more than 35 CAG repeats. The clinical phenotype of SCA2 includes a progressive cerebellar ataxia with additional features such as ophthalmoplegia, extra-pyramidal or pyramidal signs and peripheral neuropathy. We report a SCA2 large African family with several affected individuals. A major pathological allele carrying 43 CAG repeats was identified in the proband. To our knowledge, this is a first report of a SCA disorder described in Central African patients, thus indicating the need to consider this diagnosis in young African ataxic patients.

Haemophilus influenzae type b conjugate vaccine impact against purulent meningitis in Rwanda.

Rwanda introduced Haemophilus influenzae type b (Hib) conjugate vaccine in January 2002 and simultaneously implemented pediatric bacterial meningitis surveillance at a major referral hospital in the capital Kigali. We reviewed clinical and laboratory information collected during January 2002 to June 2006. Due to a variety of laboratory limitations, only eight confirmed Hib cases were identified, all before 2004. However, the proportion of cerebrospinal fluid with purulence decreased from 26.0% during 2002, to 15.9% during 2003, 9.7% during 2004 and 8.4% in 2005 (p<0.001). Vaccine effectiveness of two or three doses of Hib vaccine against purulent meningitis was 52% (95% confidence interval, 5-75%). In an African setting with few resources and in which few confirmed Hib meningitis cases were identified, Hib vaccine impact nevertheless could be demonstrated against the outcome of purulent meningitis and was found to be high.
