Flu Impact: How Hospitals Are Being Affected This Winter

Hospitals across the UK are experiencing significantly higher levels of flu cases this winter, placing increasing pressure on healthcare services. The NHS in England has issued a “high alert” after recording the highest number of flu-related hospital cases ever seen for this time of year during the week ending 14 December.

Health authorities collect flu-related hospital data differently across the UK, reflecting regional healthcare systems and reporting methods.

How Flu Cases Are Measured Across the UK

• England:
  Reports the weekly number of hospital beds occupied by patients with laboratory-confirmed flu cases.
  Data is published at the NHS Trust level, which includes hospitals and community healthcare providers.

• Scotland:
  Counts patients admitted to the hospital who tested positive for flu within 14 days before admission or up to 48 hours after admission.
  Data is provided at the NHS Health Board level.

• Wales:
  Reports weekly hospital patients with laboratory-confirmed flu cases, using test results taken up to 28 days before admission or within two days after admission.
  Figures are also reported at the Health Board level.

• Northern Ireland:
  Tracks the number of new flu cases acquired outside the hospital that resulted in hospital admission.
  Data is provided at the Health and Social Care Trust level.

The rising number of flu cases has led to increased demand for flu vaccinations, causing shortages of flu jab appointments across parts of England.
