A practical training session aimed at strengthening Ghana's wastewater-based surveillance system took place today, with health professionals receiving hands-on instruction in sample collection and data management. The session was led by Prof. John Odoom, Head of the Polio Laboratory at the Noguchi Memorial Institute for Medical Research, and Dr. Michael Owusu of the Kwame Nkrumah University of Science and Technology (KNUST).

The training focused on equipping participants with the skills needed to accurately collect and process wastewater samples using both Grab and Moore methods. Participants were guided through technical procedures to ensure that knowledge gained could be effectively applied in the field.

As part of the program, trainees visited the Nsukwao wastewater site in the Eastern Region for an on-site demonstration. Prof. Odoom emphasized the importance of selecting appropriate sampling points and adhering strictly to safety protocols to minimize the risk of pathogen exposure. “The accuracy of our surveillance depends on the quality and safety of our sample collection,” he noted.

A key concern raised during the training was the integrity of surveillance data. Representing the Eastern Regional Director of Health Services, Deputy Director of Public Health Dr. Moses Barima Djimatey expressed concern over frequent data entry errors. “Discrepancies and missing information compromise the reliability of our surveillance system,” he stated, urging participants to ensure accuracy and consistency in reporting.

In closing, Dr. Dennis Laryea, Deputy Director of the Disease Surveillance Department, reminded participants of the importance of preventing cross-contamination and maintaining personal safety during fieldwork. He encouraged regional supervisors to coordinate closely with their teams and ensure that all logistical needs are addressed ahead of field activities.

This training marks a significant step toward strengthening Ghana’s capacity to monitor public health threats through wastewater surveillance.
