Aussie flu UK: How long do symptoms of the virus last? Will the flu jab protect you?

Aussie flu, the H3N2 strain of flu which was given its name after it caused problems in Australia during its winter, is now infecting people in the UK. 

Shock figures released by Public Health England last week revealed 85 people have died from influenza since October 5, with 27 of those going in the first week of January. 

The figures also revealed almost Almost 2,000 people have been hospitalised by flu this winter, and one in four of those cases were caused by deadly Aussie flu. 

But for those knocked down by the illness, how long do symptoms generally last? 

The symptoms of Aussie flu are the same as Aussie flu but have been described as more severe. 


The NHS outlines the nine flu symptoms to look out for: 

  • A sudden fever - a temperature of 38C or above 
  • Aching body 
  • Feeling tired or exhausted 
  • Dry, chesty cough
  • Sore throat
  • Headache 
  • Difficulty sleeping
  • Loss of appetite
  • Diarrhoea or tummy pain
  • Nausea and being sick 

Does the flu jab protect against Aussie flu?

But can the flu jab protect against the potentially deadly Aussie flu?

Dr Ben Coyle, medical director at the Now Healthcare Group, says the flu vaccine can act as protection. 

“Yes the jab can help. It may not work in all instances because of the possibilities of the viruses mutating, but you definitely won’t be protected if you don’t have it.

“It’s still available so get it done!”
