Cameroon Adopts Unified Methodology to Enhance Zoonotic Data Quality
From June 22 to 26, 2026, multisectoral stakeholders convened in Ebolowa, Cameroon, to validate a common methodology aimed at improving the quality, verification, and processing of health data. The Zoonoses Program organized this workshop to refine the data verification and treatment procedures for the COHIS platform, a digital system designed for collecting, sharing, and analyzing information across human health, animal health, and environmental sectors. The initiative received technical and financial support from STRIDES (Strengthening Tools for Responsive Integrated Disease Surveillance), a program dedicated to bolstering national disease surveillance systems. Participants, including COHIS focal points from various ministries and partner organizations, critically assessed current data verification, transmission, and processing workflows. This review identified existing gaps, bottlenecks, and primary sources of erroneous data within the multisectoral data streams. Consequently, the workshop resulted in the adoption of a harmonized quality control methodology. This new approach incorporates filters for detecting outlier values, protocols for anomaly alerts, and standardized criteria for data acceptance. The overarching goal is to increase the reliability of data generated by COHIS, thereby enhancing decision-making processes for the prevention, detection, and response to zoonotic diseases.
This initiative represents a crucial step in standardizing data governance for public health surveillance in Cameroon. By establishing a unified methodology for the COHIS platform, the government aims to mitigate data integrity issues that could compromise the accuracy of zoonotic disease monitoring. Such efforts are vital as the interconnectedness of human, animal, and environmental health systems, often termed 'One Health,' becomes increasingly recognized as a critical factor in pandemic preparedness. The adoption of harmonized quality control measures, including outlier detection and alert protocols, addresses systemic challenges in data collection and processing. Looking ahead, the effectiveness of this methodology will depend on consistent implementation, ongoing training for personnel across all involved sectors, and the robustness of the STRIDES program's continued support. Future advancements may involve integrating advanced analytics and AI-driven anomaly detection to further refine data accuracy and predictive capabilities in anticipating zoonotic outbreaks.
