Dozens in hospital with the flu at Great Western Hospital
Bosses at Swindon's GWH are warning beds are filling up - amid a nationwide spike of the winter virus
NHS bosses say demand on hospitals shows 'no signs of letting up'.
Rising cases of winter illness, including the flu, are sparking critical incidents across the country.
They've been declared at trusts in hospitals in Northamptonshire, Cornwall, Liverpool, Hampshire, Birmingham and Plymouth.
Some have imposed visitor number restrictions.
It's leading to some longer waits in A-and-E, and non-urgent patients asked to consider other options.
A Great Western Hospitals NHS Foundation Trust spokesperson said: "Like many hospitals across the country, we are experiencing a rise in flu admissions, which is common during the winter months.
“Currently, we have around 48 patients in our hospital with the flu.
“Flu cases often increase in winter, and in many instances, symptoms can be effectively managed at home with plenty of rest and fluids. If anyone is concerned about their symptoms, we recommend contacting NHS 111 in the first instance.
“We encourage those who are eligible to get the flu vaccine to protect themselves and others during this flu season."
