The Global Polio Eradication Initiative remains relevant only if acute flaccid paralysis (AFP) surveillance systems maintain optimal performance. Regular evaluations of these systems are essential to identify shortcomings, enhance capacity, and ensure an appropriate response. In this context, a comprehensive analysis of the documentation and communication methods used during AFP case investigations was conducted in the Ogou health zone in Togo. This assessment aimed to highlight potential gaps and propose corrective measures to strengthen the fight against polio. Methods: A cross-sectional study was carried out across 13 primary healthcare centers, the district health laboratory, and the national reference laboratory, which are critical links in the AFP epidemiological surveillance chain. Data were collected using a structured grid to extract information from registers, suspect case investigation forms, AFP notification forms, stool sample accompanying forms, and weekly reports. Additionally, semi-structured individual questionnaires were administered to personnel involved in AFP case investigations to gather their perspectives and experiences. Results: The AFP surveillance system’s responsiveness was generally satisfactory, with a median alert notification time of 18 hours, below the prescribed threshold of 24 hours. Report completeness was also deemed satisfactory. However, timeliness in transmitting results, both by the national reference laboratory and the primary healthcare centers, remained insufficient. Evaluating the information management system revealed logistical and organizational deficiencies within the AFP surveillance system.
