Abstract
Despite the high investment on Measles surveillance activities, frequent measles outbreaks still occur in Kaduna State. We evaluated the surveillance system to adentify gaps in its operations.We adapted the updated CDC guidelines on surveillance evaluation to assess the systems usefulness, representativeness, simplicity, timeliness, stability and acceptability. Our findings showed that the surveillance system is still useful however there were marked deficiencies in the timeliness and completeness of weekly reporting.
