Background The WHO AFRO Regional Data Hub (RDHUB) aims to consolidate, standardize, and transform health data into actionable intelligence, supporting country-level health planning, regional monitoring, and global health reporting. The RDHUB initiative is designed to equip WHO leadership, member states, and stakeholders with comprehensive insights on disease prevention and control, emergency preparedness, response, and health systems strengthening. The RDHUB will consolidate regional health datasets for the WHO African Region (AFRO) and establish seamless linkages with national data repositories. This integration will enable advanced analytics, including predictive modelling, scenario-based analysis, machine learning, geospatial analysis, and the application of innovative AI-powered tools such as chatbots. Furthermore, the platform aims to foster a culture of data use both within WHO and among external stakeholders, strengthen collaboration with Member States, and support evidence-based decision making in alignment with the WHO General Programme of Work (GPW 14). A critical component of the RDHUB is the integration of innovative technologies including geospatial analysis capabilities (GeoNode/GeoServer), AI-driven chatbots, predictive analytics models, and interactive visualization tools to enhance accessibility, user interaction, and real-time dissemination of health data insights. Progress to Date
Significant foundational work has been completed during the initial consultancy period (November–December 2025), establishing the technical infrastructure necessary for advanced analytics and AI implementations. Key accomplishments include: Data Engineering Infrastructure: Development of end-to-end data pipelines in Microsoft Fabric for Immunization coverage indicators and AFP Laboratory surveillance data, implementing comprehensive data cleaning using PySpark, column standardization, multi-layered validation, table restructuring, and statistical processing. These pipelines establish the data quality foundation necessary for predictive analytics and machine learning implementations.
Geospatial Analysis Capabilities: Comprehensive geospatial analysis conducted for health facility accessibility assessment using QGIS, ArcGIS Pro, and AccessMod, including Digital Elevation Model (DEM) processing for terrain analysis, proximity and accessibility modelling, spatial data cleaning, and professional cartographic output production.
CKAN Metadata Platform Configuration: Implementation of country mapping, organizational hierarchy setup, API proxy configuration for dataset retrieval, and development environment establishment enabling dataset discovery and programmatic access.
Business Requirements Documentation: Substantial contributions to the RDHUB Business Requirements Document, articulating platform objectives, defining core solutions and value propositions, and establishing functional requirements that guide technical implementation.
This foundational phase has successfully established the data infrastructure, geospatial capabilities, and metadata cataloguing systems that are prerequisites for the advanced analytics, AI/ML modules, and interactive dashboards specified in the platform vision. As the RDHUB approaches its Beta version launch in Q2 2026, WHO AFRO requires continuation of specialized GIS and Data Engineering consultancy for a six-month extension period (June–November 2026) to complete deliverables dependent on the now-established foundational infrastructure. These activities—including advanced analytics development, geospatial infrastructure deployment (GeoNode/GeoServer), AI/ML module integration, chatbot deployment, platform optimization, launch preparation, post-launch monitoring, requirements gathering, and technical support—were not feasible before data pipelines, geospatial workflows, and metadata systems were operational. This extension ensures the MVP successfully delivers comprehensive health intelligence capabilities for the African Region.
