Syndromic surveillance is the process of collecting, analysing and interpreting health-related data to provide an early warning of human or veterinary public health threats, which require public health action.
PHE’s real-time syndromic surveillance team (ReSST) coordinates several national syndromic systems: we collect and analyse anonymised health data from several sources, looking for trends indicating higher-than-usual levels of illness and publish bulletins to keep public health professionals up to date.
Syndromic surveillance summary
This weekly summary of trends and important public health messages draws information from each of the Public Health England syndromic surveillance
Remote health advice syndromic surveillance system
Monitoring patterns in phone calls to the NHS 111 service each day across England, to track the spread of infectious diseases like flu and norovirus. We examine call levels on a daily basis, and publish a weekly report.
These data can provide early warning of community-based infectious diseases.
Monitors the number of unscheduled visits and calls to GPs every day during evenings, overnight, on weekends and on public holidays. This system covers approximately 80% of the England population and complements the existing GP surveillance systems that cover daytime consultations.
We analyse the data on a daily basis, and publish a weekly report.
Emergency department syndromic surveillance system
The Emergency Department Syndromic Surveillance System (EDSSS) monitors the daily visits in a network of emergency departments across England (and Northern Ireland to March 2018). We analyse this data daily, and publish a weekly report.
