What is sepsis?

Sepsis is when your body has an extreme response to an infection.  You need immediate medical attention, as it can cause death or permanent damage to your body without treatment.

Sepsis always starts with an infection. Infections which may cause sepsis can be anywhere in the body, such as in the lungs, skin, abdomen or gut (for example, after surgery), and urinary tract. Not all infections lead to sepsis. However, if you have already seen your doctor and have been told you have an infection, and you are worried that you or your child are getting worse, then go back for another review and ask, ‘could it be sepsis?’

Sepsis does not spread from person to person. However, the original infection that caused sepsis can spread between people.

Who is at risk of sepsis?

Sepsis can affect anyone.

Some people are more likely to develop sepsis. This includes those who:

  • are 5 years of age and under, especially babies under 3 months of age
  • are 65 years of age and older
  • are pregnant or have recently given birth (within 6 weeks)
  • have a weak immune system
  • have an existing, chronic illness such as diabetes, lung disease, cancer or kidney disease
  • have had sepsis before
  • have recently been in hospital or had a severe illness
  • are Aboriginal or Torres Strait Islander.

How is sepsis prevented?

You can lower your risk of sepsis by preventing infection and managing chronic illnesses.

  • Practise good hygiene: wash or sanitise your hands often and cover your coughs and sneezes.
  • Do not share personal items (such as razors or toothbrushes).
  • Cover cuts and wounds and keep them clean until healed.
  • Keep up to date with your recommended vaccinations.
  • Speak to your doctor regularly if you have a chronic health condition such as diabetes, lung disease or kidney disease. Follow their advice, including taking prescribed medicines.
  • Stay at home if you are sick to protect others.

How is sepsis diagnosed?

There is no single test for sepsis. To see if you have sepsis, a doctor will:

  • ask you about your symptoms
  • examine you
  • perform some tests.

How is sepsis treated?

People with sepsis are treated in hospital. You may need to be treated in an intensive care unit (ICU) if you are really sick. Treatment may include:

  • medicines such as antibiotics
  • fluids through a drip (needle in your arm)
  • breathing support
  • surgery.

Sepsis is serious and may cause death or permanent damage to your body without treatment. Treatment for sepsis works best when started as soon as possible.

What is post-sepsis syndrome?

People who recover from sepsis can sometimes experience long-term physical, psychological and emotional effects from sepsis. This is called ‘post-sepsis syndrome’. It can last between 6 and 18 months or sometimes longer.

Effects of post-sepsis syndrome can include:

  • difficulty sleeping (such as insomnia)
  • nightmares, hallucinations, flashbacks or panic attacks
  • muscle and joint pain that can be severe and disabling​
  • feeling very tired
  • inability to concentrate
  • confusion
  • loss of confidence and self-belief.

Speak to your doctor if you are concerned about post-sepsis syndrome.​​
