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.

Background: Antimicrobial resistance (AMR) has emerged as a leading global health and economic threat of the 21st century, with Africa bearing the greatest burden of mortality from drug-resistant infections. Optimization of the use of antimicrobials is a core strategic element of the response to AMR, addressing misuse and overuse as primary drivers. Effectively, this requires the whole society comprising not only healthcare professionals but also the public, as well as the government, to engage in a bottom-up and a top-down approach. We determined the progress of African national governments in optimizing antimicrobial drug use.Methods: From September 2021 to June 2022, all 47 member states of the World Health Organization African region (WHO AFRO) were invited to participate in a survey determining the implementation of strategies to optimize antimicrobial use (AMU). We used the WHO antimicrobial stewardship (AMS) assessment tool, National core elements—A checklist to guide the country in identifying existing national core elements for the implementation of AMS Programs, to obtain information from national AMR focal persons. The tool consists of four sections—national plans and strategies; regulations and guidelines; awareness, training, and education; and supporting technologies and data—with a total of 33 checklist items, each graded from 0 to 4. The responses were aggregated and analyzed using Microsoft Excel 2020®.Results: Thirty-one (66%) of the 47 countries returned completed forms. Only eight (25.8%) countries have developed a national AMS implementation policy incorporating defined goals, targets, and operational plans. There are no budget lines for AMS activities in 23 (74.2%) countries. The WHO Access, Watch, Reserve (AWaRe) classification of optimizing AMU has been integrated into the national essential medicines list or formulary in 19 (61.3%) countries, while the incorporation of the AMS principles and WHO AWaRe classification into national clinical guidelines for the management of infections is present in only 12 (38.7%) and 11 (34.5%) countries, respectively. Although regulations on the prescription-only sale/dispensing of antibiotics are present in 68% of countries, their enforcement is poor. Systems identifying pathogens and antibiotic susceptibility for optimal use of antibiotics are lacking in 38% of countries.Conclusion: In Africa, wide gaps exist in the governments’ implementation of the core elements of optimizing antimicrobial drug use. Responding to AMR constitutes a long journey, and technical and financial support needs to be deployed to optimize the use of antimicrobials.

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.

: Zambia experienced the largest cholera epidemic in the country’s history in 2023–2024; however, the antimicrobial susceptibility profile of Vibrio cholerae during the epidemic is unknown. A total of 2,384 stool samples were collected from suspected cholera cases in Eastern, Lusaka, and Luapula provinces in Zambia from January 2023 to March 2024. Among them, 549 (23.5%, n = 549 of 2,341) were culture positive for V. cholerae O1, and antimicrobial susceptibility results were available for 431 (78.5%, n = 431 of 549). Sensitivity for tetracycline was 84.5% (n = 316 of 374) in Lusaka, whereas it was 100% in Eastern and Luapula provinces. Isolates resistant to azithromycin were found only in Lusaka (1.6%, n = 1 of 61). Sensitivity for ciprofloxacin was 81.8% (n = 260 of 318) in Lusaka province, whereas it was 100% in other provinces. Our results suggested an increased prevalence of antimicrobial resistance in V. cholerae against the first- and second-line antibiotic treatments, particularly in the capital. Careful monitoring of the regional antibiogram is warranted.

Enteric infections due to viral pathogens are a major public health concern. Detecting the risk areas requires a strong surveillance system for pathogenic viruses in sources such as wastewater. Towards building an environmental surveillance system in Zambia, we aimed to identify group A rotavirus (RVA) and human adenovirus (HAdV) in wastewater. Convenient sampling was conducted at four study sites every Tuesday for five consecutive weeks. The research team focused on three different methods of viral concentration to determine the suitability in terms of cost and applicability for a regular surveillance system: the bag-mediated filtration system (BMFS), polyethylene glycol-based (PEG) precipitation, and skimmed milk (SM) flocculation. We screened 20 wastewater samples for HAdV and RVA using quantitative polymerase chain reaction (qPCR) and conventional polymerase chain reaction (cPCR). Of the 20 samples tested using qPCR, 18/20 (90%) tested positive for HAdV and 14/20 (70%) tested positive for RVA. For the genetic sequencing, qPCR positives were subjected to cPCR, of which 12 positives were successfully amplified. The human adenovirus was identified with a nucleotide identity range of 98.48% to 99.53% compared with the reference genome from GenBank. The BMFS and SM flocculation were the most consistent viral concentration methods for HAdV and RVA, respectively. A statistical analysis of the positives showed that viral positivity differed by site (p < 0.001). SM and PEG may be the most appropriate options in resource-limited settings such as Zambia due to the lower costs associated with these concentration methods. The demonstration of HAdV and RVA detection in wastewater suggests the presence of the pathogens in the communities under study and the need to establish a routine wastewater surveillance system for the identification of pathogens.
