I just received my copy of the book: Biosruveillance methods and case studies edited by Taha Kass-Hout and Xiaohui Zhang. I first met Taha in cyberspace when he was with InSTEDD, we had started a Google group: Biosurveillance, which we use as a knowledge-base. Their approach to disease surveillance was through “event-based surveillance” and our approach was through “indicator-based surveillance” but both converging at finding signals for timely public health alerts that would advocate early control measures. We had contributed three chapters in the context of the Real-Time Biosurveillance Program pilot (RTBP) – Chapter 9: “The role of Data Aggregation in Public Health and Food Safety Surveillance” – Artur Dubrawski Chapter 13: “User Requirements towards a Real-Time Biosurveillance Program” – Nuwan Waidyanatha and Suma Prashant Chapter 14: “Using Common Alerting Protocol to Support a Real-Time Biosurveillance Program in India and Sri Lanka” – Gordon A. Gow and Nuwan Waidyanatha.
