- Abstract
The article discusses the challenges of monitoring and controlling dengue, a major public health problem in many endemic areas. Due to the lack of a vaccine, dengue control relies on controlling the mosquito vector. However, formal surveillance systems have limitations, such as delays in reporting and hierarchical reporting structures. To address these drawbacks, complementary informal surveillance tools have been developed, including event-based surveillance systems and the analysis of real-time search queries. The authors of the article apply searchstream surveillance techniques to monitor dengue and find a strong correlation between dengue-related search volumes and case counts reported by traditional surveillance systems. However, there are concerns about model over-fitting and the potential for misleading spikes in search volumes. The authors conclude that web-based surveillance tools provide an additional tool in the surveillance toolbox, with advantages and limitations, and can help improve situational awareness of dengue activity.
