This is how the flu can actually kill you

This week, you might have read reports of the Australian flu doing the rounds and even taking people’s lives. It sounds pretty scary, right?

While in the majority of cases the flu doesn’t end in death, in some eventualities it can. However, most flu-related deaths occur in older people and young children because they’re most vulnerable. But exactly how does this happen?

Essentially, it’s when the body tries so hard to heal itself that it actually ends up doing the opposite. According to infectious disease physician at the Johns Hopkins University Center for Health Security, Amesh Adalja, it’s not the disease itself that kills you, but the subsequent interactions the disease has with your body.

According to Live Science, who looked into it in more depth, the flu virus “hijacks human cells in the nose and throat to make copies of itself”. This flood of cells triggers a person’s immune system to release more antibodies, white blood cells and inflammatory molecules to try to overrule the virus.

In most healthy people, this response usually proves successful after a week or so, but occasionally things can go wrong. In people with a weaker immune system than usual, for example, a secondary infection can take hold while they’re already exposed. These infections can either take hold of the lungs, or can cause various other organs to shut down.

In other cases, the immune system’s response is actually too strong, and the extra defences end up causing potentially fatal damage to the body by destroying vital tissues in the lungs that help transport oxygen to the blood.

According to the UK’s Office of National Statistics, the winter of 2016/2017 saw a much higher mortality rate in winter than in previous years – however it was predominantly older people that suffered more than young. The increase in deaths was thought to be “due to the predominant strain of flu prevalent during the 2016 to 2017 winter, which had greater impact on the elderly than the young.”

Aussie flu: Who’s most at risk?

As mentioned above, it’s mainly the very old and the very young who are most at risk when it comes to flu. However, there are a few other circumstances in which you should visit your doctor immediately if you display any flu symptoms. The full list of ‘at risk’ groups includes…

  • Elderly people
  • Very young children
  • Pregnant women
  • People with a pre-existing or chronic health condition
  • People who live in a care home or other long-stay facility

Symptoms of the Australian flu are just a more severe form of those experienced with any other flu virus. They include…

  • A sudden fever, with temperatures of 38C and above
  • Aching body
  • Feeling tired or exhausted
  • A dry, chesty cough
  • A sore throat
  • A headache
  • Difficulty sleeping
  • Loss of appetite
  • Diarrhoea and / or tummy pain
  • Nausea and / or vomiting

Unfortunately there isn’t a definite treatment for flu, so make sure you stay inside, keep warm and drink plenty of water.
