TMHG528_Wk4_TanaphumWichaita – Hybrid Dengue Surveillance System

[Tanaphum Wichaita]

My presentation is about hybrid dengue surveillance system in Northern Thailand, specifically focusing on its hybrid design that combines syndromic and disease-specific surveillance.

Hello Tanaphum, thank you for sharing your proposed hybrid system on dengue surveillance. I think it is a good idea to use both disease and syndromic surveillance. Additionally, having a weak definition will allow you more flexibility in your system. Regarding your data flow, using models and algorithm can support decision-making process. However, it would be better if I could learn more about the data flow in detail like how you will collect those data from the frontline, for example, schools or clinics.

Your presentation is insightful and I’ve never thought that weak case definition would be helpful and useful in detecting potential cases earlier than confirmed cases for a more proactive response. I think that you’ve already been familiar with the flow of how a surveillance system works since the data flow diagram is impressive, I am curious to learn about how the analysis algorithms work. Regarding the weak case definition, I wonder what epidemiological factors or clinical features in identifying weak cases for dengue are.

Thank you for sharing your presentation on the hybrid surveillance system. The integration of surveillance methods is a strong approach for early detection. Regarding the use of a weak definition to identify suspected dengue cases, I suggest adding indicators to measure the accuracy of case detection. If the system has high accuracy and minimizes false positives, it can greatly support rapid outbreak response.
