The deadly "Aussie flu" virus has spread to five more UK towns in the past 24 hours as it moves rapidly across the country.

Perthsire, Inverness, Preston, Glasgow and Midlothian - previously untouched - have now all reported cases of the dangerous new H3N2 strain of Influenza A.

The NHS is braced for one of the worst flu seasons in 50 years after a surge in infections in the UK, with hotspots being Plymouth, Doncaster and Belfast, reports Daily Mail.

Areas unaffected by the flu are rapidly diminishing, with only Dorchester, the Brecon Beacons area, Telford, Dartford and the City of London having no reported cases.

However, the online FluSurvey map, which updates every three minutes, relies on self-reported data from patients, meaning the true figure is likely to be much higher.

Plymouth has been hit the hardest, with 14 new cases in the past three weeks, according to Public Health England figures.

At least 1,649 people have been struck down by the potentially deadly strain in England and Wales within a week over the Christmas period.

A further 112 patients were admitted to non-emergency hospital wards - an increase from a mere five the week before.

Some 17 people in England and Wales were admitted to intensive care in the past week, according to a government report.

And fears of fatalities have been growing after the lethal virus claimed its first victims in Ireland.

Experts fear the virulent flu strain could prove as deadly to humanity as the Hong Kong flu in 1968, which killed one million people.

Flu kills an average of 8,000 people every year in England and Wales, but experts previously warned that this number could rise significantly if the Aussie flu struck.

Some 55,000 operations have been cancelled as hospitals struggle to cope with a surge in patients.

Doctors are cancelling holidays and working late into the night to try to manage the demand after being told to keep patients out of hospitals as the NHS struggles.

The soaring cases, which jumped by 48 per cent over the space of a week, has been blamed for adding extra pressure onto an already stretched health service.

Yesterday a British mum told of her horrific experience with the illness.

She originally thought it was a hangover after drinking too much prosecco, but quickly realised it was much more serious after it left her bed-bound for five weeks.

Natalie Shand, 39, who said her body ached all over, told the Mirror: "I was bedbound for six days in total.

"Then I was OK for two weeks and then by December 23 it knocked me off my feet again for hours at a time.

"I had it for five weeks."

Middlesbrough mum Paula Kay, who started suffering symptoms on Boxing Day, believes she picked up the bug while working on a panto.

The 36-year-old said she first had a tight chest and lost her voice, before developing a dry cough and trouble with her sinuses.

"I would say the pain is about a six out of ten - but I have a high pain threshold," she said.

"I've had to force myself to eat and I just felt wiped out.

"I would do a few little jobs around the house ad it felt like a week's work.

"On one day I just kept falling asleep and spent about 24 hours on the sofa.

"I've had worse but I've never known flu last this long."
