Aussie flu symptoms: NHS reveals secret to lowering your risk of deadly infection

Aussie flu has hospitalised almost 500 people since the beginning of October, latest Public Health England (PHE) figures have revealed.

The deadly viral infection has swept across the UK, and has been recorded in every postcode of the country.

But, you could prevent infection from the H3N2 virus by simply keeping warm, according to the NHS.

Cold weather increases the risk of flu, pneumonia, hypothermia and heart attacks, it said.

“Keeping warm over winter helps prevent colds, flu and even more serious health conditions,” tweeted NHS Choices.

“Several layers of clothes are better for staying warm than one chunky layer.”

The NHS added: “If you're not very mobile, are 65 or over, or have a health condition, such as heart or lung disease, heat your home to at least 18°C [65°F].

“If you start to feel unwell, even if it's a cough or cold, don't wait until it gets more serious. Seek advice from your pharmacist.”

The advice comes after claims that the Aussie flu epidemic could continue for another three months.

Australian scientists revealed that outbreaks of H3N2 typically last for about 15 weeks.

The number of people visiting GPs over flu-related illnesses increased 42 per cent during the second week of January.

The best way to prevent infection is to get the flu jab, PHE said.

Aussie flu symptoms include sore throats, vomiting, diarrhoea, fever, headaches and difficulty sleeping.

Symptoms are similar to normal flu, but they tend to be more severe and last longer.

You could lower your risk of infection by regularly washing your hands, and by avoiding crowded areas.

If you think you’re infected with Aussie flu, you shouldn’t see your GP, as you could spread the virus further.

Only see a doctor if you’re over 65, are pregnant, or have a long-term medical condition.
