Syndromic surveillance: systems and analyses

These data collection and analysis systems provide an early warning system of the spread of illness across England.

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 the 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.

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.
