Sepsis is the leading cause of harm in children worldwide and is especially dangerous to those under five years of age.
Sepsis can be treated if caught early. Early treatment saves lives.
Almost any infection can lead to sepsis, for example a simple cut, urinary tract infection (UTI), or a more serious infection like pneumonia. It can develop very quickly, even if you’re already taking antibiotics.
Don’t be afraid to ask your doctor or hospital health professional: 'Could it be sepsis?'
Trust your instincts – if something feels seriously wrong, don’t wait, speak up.
Sepsis is life threatening and needs immediate treatment.
Call Triple Zero (000) or go to your nearest emergency department if:
• your baby is under 3 months and has a fever (>38 degrees Celsius) or your child is seriously unwell and getting worse
• you have already seen a doctor, but your child is still sick and not getting better.
