A deadly virus, known as Aussie Flu, is currently attacking Ireland and the UK - with a number of deaths reported by the ''H3N2'' strain.
The deadly virus triggered almost three times the number of cases in Australia, which earned it the nickname "Aussie flu".
Dr Kevin Kelleher from the HSE confirmed the news:
"There have been a few deaths already... under 10 people have died so far this year.
I don't give specific numbers when it's less than 10 because people could be identified.
The most important thing is that if people think they’ve got it is to stay at home and look after themselves."
Dr Kelleher urged people to get the vaccination ASAP. He said:
"The HSE is continuing to encourage people to get the flu vaccine - especially those in high risk groups.
Older people, children, and people with underlying health conditions are at particular risk and it’s feared that the number of cases here could rise dramatically over the coming weeks.
I am concerned that any significant increase in cases could pose a serious threat to our already overburdened hospital system.
In the majority of cases, this flu, while serious, can be treated at home.
However there will always be more severe cases, which will need acute medical intervention."
