Syndromic surveillance systems to detect outbreaks of gastroenteritis in high-income countries: a scoping review

This scoping review underscores the potential of syndromic surveillance for detecting gastroenteritis outbreaks in high-income countries. While most data sources could provide a signal for early outbreak detection, the findings highlight the need for more comprehensive evaluations, improved data representativeness, and the integration of health-seeking behaviour considerations in syndromic surveillance system design. These areas should be the focus of future research to enhance the effectiveness of syndromic surveillance for gastroenteritis in high-income countries.
