ABSTRACT: Back ground: Notifiable Disease Surveillance system serves as an early warning system for public health emergencies. Since January 2013 to August 2014, Beitbridge never submitted T2 forms to the province. Four suspected cases of rabies were reported through the generic report. The electronic District Health Information System 2, T2 forms had not been updated. This discrepancy may imply under reporting of Notifiable Diseases. The study was conducted to evaluate the NDSS in Beitbridge district. Methods: Descriptive cross-sectional study was conducted. Health workers in sampled health facilities were interviewed using questionnaires. Checklists were used to assess resource availability. Epi InfoTM was used to calculate frequencies and proportions. Results: From 11 facilities, 53 respondents were interviewed of which the 59% were females. For Knowledge, 57% recalled at least 9 Notifiable diseases, 11% knew the T1 form required to notify. Respondents willing to participate in the NDSS were 87%. Responsibility to notify was placed other health workers other than themselves by 55% of the respondents. All facilities did not have completed T1 forms. T1 forms were available in 1/11 health facilities. Three outbreaks were reported using the Weekly Disease Surveillance System (WDSS). NDSS information was used for planning and mobilizing resources for indoor residual spraying. It costs an average $12.15 to notify a single case, against $1.50 if it was electronic. Conclusion: NDSS is acceptable, simple, flexible, unstable, not sensitive and useful. Reasons for under reporting were lack of forms, lack of induction and poor knowledge on the NDSS. The cost of operating the NDSS could be reduced if the system is electronic. T1 forms and guidelines for completing the forms should be distributed to all health facilities. On the job training of health workers through tutorials, supervision is recommended.
