We used CDC MMWR attributes guidelines for evaluating public health surveillance systems; usefulness, simplicity, acceptability, timeliness, representativeness, flexibility, stability, data quality, sensitivity, and Positive Predictive Value. We visited four districts selected based on Non-polio AFP rate performance and sixteen health facilities randomly selected using probability proportional to catchment population size. We conducted key informant interviews for 20 HCWs using a semi-structured questionnaire. We also reviewed AFP surveillance CIFs from 2020-2022. We summarized data using frequencies and proportions.
