Why is this work needed?
When a public health threat, like a flu epidemic, emerges it is important that public health professionals are made aware as quickly as possible and act based on accurate and current data.
What is happening?
Syndromic surveillance is the process of collecting, analysing and interpreting health-related data so that there is an early warning for any public health threats. At Public Health England, the real time syndromic surveillance team coordinates several national systems that record this data. They analyse the collected data and look for trends that could indicate illness levels that are higher than usual or expected, and publish bulletins to keep public health professionals up to date.
What are the benefits?
This system allows public health bodies in the UK to understand trends in illness and swiftly identify any emerging crises. It is vital that data is combined in this way so that individual cases of a disease can be placed in the wider context. For example, it is important to understand if a single episode of a particular flu is an isolated incident or part of a larger epidemic.
What type of data is involved?
This process combines a range of anonymised data, including trends in calls to the NHS 111 service, visits to GP surgeries and out of hours services, and daily visits to the emergency departments.
What is the legal basis for accessing the data?
Only anonymised data are received by the Public Health England real-time syndromic surveillance team. Before leaving Public Health England, these data are aggregated, and presented graphically, to national, regional and local level in surveillance bulletins.
Who is funding and collaborating on this work?
This work is government funded because it is part of the function of Public Health England.
