AbstractWe evaluated the Singapore Ministry of Health's sentinel surveillance system for influenza virus, which included the monitoring of virological samples from patients with influenza-like illness seen at government primary care clinics and private general practitoner clinics in 2011-12. Using a systematic approach, we analysed weekly data collected for the full two year period from 2011-12. Criteria applied for evaluation were based on the US Centers for Disease Control's Guidelines for Evaluating Public Health Surveillance Systems, and included quality of the data, acceptability and geographic representativeness. The current surveillance system is satisfactory but could be enhanced by focusing on strategies to improve its acceptability and representativeness. We recommend enhancing quality of the data submitted through further engagement and information sharing with stakeholders involved.
