Abstract: Background: Notifiable disease surveillance system (NDSS) data guides immediateaction for events of public health importance. In July 2016, 12 patientssuspected of typhoid were reported to Centenary District Medical Officerby phone. Following reporting, notification forms (T1) were not submittedto district, hence province did not receive district consolidated report (T2)for the notifications. This implies underreporting of notifiable diseases. Studywas conducted to evaluate NDSS in Centenary district. Methods: Using updatedCentres for Disease Control and Prevention (CDC) guidelines, descriptivecross sectional study was conducted among health workers sampled fromall health facilities in Centenary district. Interviewer administered questionnaireand checklists were used to collect data, assess data quality and resourceavailability. Epi InfoTM 7 generated frequencies and proportions. Results: Weinterviewed 50 respondents from 13 health facilities and 64 were females.Health worker knowledge was rated low, 26 knew whom to notify and 40 knew forms are completed in triplicate. Reasons for failure to notify notifiablediseases included, unavailability of reporting forms 32 and lack of reportingguidelines 16 . Ninety-two percent were willing to participate. Four healthfacilities had at least six standard case definitions. The first two patients wereonly diagnosed at district level. NDSS information was used to procure antirabiesvaccine and implement control measures. Conclusion: NDSS is useful,acceptable, unstable and not sensitive. Failure to notify was mainly due to lackof knowledge on NDSS.
