No, sepsis is not rare; it's a common, life-threatening medical emergency caused by the body's extreme reaction to an infection, affecting millions globally and leading to significant mortality, though often under-recognized by the public. Anyone can get sepsis, but the very young, older adults, and those with weakened immune systems or chronic conditions are at higher risk, making it a major health concern worldwide.
Sepsis can affect anyone, but people with any kind of infection, especially bacteremia, are at a particularly high risk. You're also at a high risk if you: Are over age 65.
Sepsis is a time critical medical emergency and a leading cause of death worldwide. In Australia at least 55,000 people develop sepsis each year and 8,000 of them die from sepsis-related complications.
Who's more likely to get sepsis
This includes bacterial, viral or fungal infections. Those that more commonly cause sepsis include infections of: Lungs, such as pneumonia. Kidney, bladder and other parts of the urinary system.
You get sepsis when your body has an extreme, damaging reaction to an infection (bacterial, viral, fungal, or parasitic), causing its own immune response to harm tissues and organs, leading to potential organ failure; it starts with any infection, like pneumonia, UTI, or a skin wound, and becomes a medical emergency when the body's defense system overreacts.
Sepsis survival rates vary significantly by severity, with mild cases often recovering, but septic shock (the most severe form) carries a high mortality, around 30-40%, though rates can exceed 50% in some studies, with death potentially occurring within hours. Overall, studies show roughly 24% mortality within 30 days for general sepsis and up to 35% for septic shock, but long-term survival is lower, with over half of survivors potentially dying within five years due to post-sepsis complications, though rates vary widely.
Early warning signs of sepsis include fever or low temperature, chills, rapid breathing or heart rate, confusion, slurred speech, extreme pain or discomfort, clammy/sweaty skin, and reduced urine output, with children potentially showing fewer wet nappies, vomiting, or a non-fading rash. These symptoms, often appearing after an infection, signal a severe body response and require immediate emergency care, as sepsis can rapidly worsen, according to the Mayo Clinic.
Is sepsis contagious? Sepsis itself is not contagious, but some of the infections that lead to sepsis (such as COVID-19 and influenza) can be spread from person to person.
[13, 14] Widespread use of antibiotics not only leads to selection for drug resistance and increases risk for Clostridium difficile infection (CDI), but also may increase a patient's risk for later development of sepsis.
The research discussed here includes the following subset of the core measure sepsis bundle, the components of which must be completed within 3 hours of presentation time: measure serum lactate level, obtain blood cultures before administration of antibiotics, and administer broad spectrum antibiotics.
Dementia has become the country's leading cause of death, according to the Australian Bureau of Statistics (ABS). The ABS released new figures on Friday that revealed dementia, including Alzheimer's disease, accounted for more than 17,500 deaths (9.4 per cent) in Australia in 2024.
Commonly cited explanations for the increase in sepsis incidence include an aging population with more predisposing comorbidities, more frequent use of immunosuppression, more invasive procedures and medical devices, and the spread of multi-drug resistant pathogens (6-8).
How long does it take for sepsis to set in? According to the Physician-Patient Alliance for Health & Safety, sepsis can progress quickly, causing death in as little as 12 hours. Sepsis Alliance states, the risk of death increases by 7.6% for every hour that passes without treatment.
The evidence behind the “golden hour” protocol
The main finding was that patients who received antibiotics within the first hour of sepsis recognition had a 79.9% chance of survival. It was also found that with every additional hour, the chance of survival decreased by 7.6%.
Early warning signs of sepsis include fever or low temperature, chills, rapid breathing or heart rate, confusion, slurred speech, extreme pain or discomfort, clammy/sweaty skin, and reduced urine output, with children potentially showing fewer wet nappies, vomiting, or a non-fading rash. These symptoms, often appearing after an infection, signal a severe body response and require immediate emergency care, as sepsis can rapidly worsen, according to the Mayo Clinic.
The reasons why some people develop sepsis as a consequence of an infection are not entirely understood – medical research institutions are working to understand this better. It's important to note that it's not possible to catch sepsis or pass it onto others.
A rapid sepsis test is defined as a blood test that, within 10 min, assesses host immune response to aid in identifying patients with sepsis or those at increased risk of developing sepsis within 3 days of hospital admission.
Many sepsis survivors have said that when they were ill, it was the worst they ever felt. It was the worst sore throat, worst abdominal pain, or they felt that they were going to die. Children developing sepsis may exhibit different symptoms, as seen below.
Stage 1: Sepsis
A high fever above 101℉ (38℃) or low temperature below 96.8℉ (36℃) A heart rate above 90 beats per minute. A bacterial infection, fungal infection, or viral infection confirmed through positive blood culture results. Rapid breathing rate higher than 20 breaths per minute.
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
These infections are most often linked to sepsis:
Most people make a full recovery from sepsis. But it can take time. You might continue to have physical and emotional symptoms. These can last for months, or even years, after you had sepsis.
Results, Reporting, and Critical Findings
Recent data showed that ICU mortality for severe sepsis or septic shock in younger patients (age < 60 years) was 45.6% as compared to 60.7% in older (age 60–80 years) and 78.9% in very old (age > 80 years) patients, with patient age an independently predictor of ICU mortality on multivariate analysis9.
