Towards a Framework for the Successful Implementation of Wastewater and Environmental Surveillance for Diarrhoeal Diseases in Sub-Saharan Africa.
Diarrhoeal diseases remain a major public health challenge in sub-Saharan Africa, prompting growing interest in wastewater and environmental surveillance (WES) as a complement to clinical surveillance. A recent study implemented WES in Burkina Faso, the Democratic Republic of the Congo, and Tanzania between January and September 2025. Monthly wastewater and surface water sampling, combined with contextual clinical data, assessed the feasibility of detecting Salmonella Typhi and Vibrio cholerae in low-resource settings. The study identified operational and institutional challenges, highlighted the importance of stakeholder engagement, and demonstrated how WES can strengthen early warning systems and inform evidence-based public health decision-making.

Harnessing Genomic and Bioinformatics for Surveillance of Pathogens in Africa: A Scoping Review of Existing Training and Gaps in Training.
Despite Africa bearing a disproportionate burden of infectious diseases, access to structured, sustainable training in genomics and bioinformatics for pathogen surveillance remains fragmented, short-term, and heavily donor-dependent. This paper, Harnessing Genomic and Bioinformatics for Surveillance of Pathogens in Africa: A Scoping Review of Existing Training and Gaps in Training, directly addresses this gap by systematically mapping available training initiatives across the continent between 2014 and 2024. It critically analyses programme design, delivery models, funding patterns, outcomes, and persistent challenges. The review identifies critical deficiencies and practical opportunities and further offers clear recommendations to strengthen long-term, locally embedded capacity for effective pathogen surveillance in Africa.

Strengthening pathogen and antimicrobial resistance surveillance through environmental monitoring in sub-Saharan Africa: stakeholder perspectives.
In the face of a rapidly changing global landscape, the threat of waterborne diseases looms large, underscoring the urgency for enhanced and comprehensive surveillance. In this latest paper, titled "Strengthening pathogen and antimicrobial resistance surveillance through environmental monitoring in sub-Saharan Africa: stakeholder perspectives," the authors delved into the intricate web of infectious disease and antimicrobial resistance (AMR) surveillance systems in three diverse sub-Saharan African countries: Tanzania, Burkina Faso, and the Democratic Republic of the Congo (DRC).
The paper emphasised the pressing need to fortify current disease surveillance measures, particularly in the context of monitoring waterborne and re-emerging pathogens, along with the ever-growing threat of AMR.

Emergence and Global Spread of Mpox Clade Ib: Challenges and the Role of Wastewater and Environmental Surveillance.
Several African countries, mainly the Democratic Republic of Congo, Burundi, and Uganda, are facing highly transmissible mpox clade Ib epidemics, prompting the World Health Organization to declare a Public Health Emergency of International Concern. It has spread to key travel hubs like Kinshasa, Bujumbura, and Kampala, increasing international spread risks. Current mitigation efforts focus mainly on medical care, diagnostics, vaccination, and infection prevention, but overlook wastewater and environmental surveillance (WES). WES can be effective in detecting hotspots and enabling rapid response through enhanced data collection and genomic sequencing. This perspective article reviews the latest outbreak situation and advocates integrating WES into response strategies.
