When germs get into a person's body, they can cause an infection. If you don't stop that infection, it can cause sepsis. Bacterial infections cause most cases of sepsis. Sepsis can also be a result of other infections, including viral infections, such as COVID-19 or influenza, or fungal infections.
What causes sepsis? Bacterial infections are the most common cause of sepsis. Sepsis can also be caused by fungal, parasitic, or viral infections. The source of the infection can be any of a number of places throughout the body.
A person with sepsis might have one or more of the following signs or symptoms: High heart rate or weak pulse. Fever, shivering, or feeling very cold. Confusion or disorientation.
The condition can arise suddenly and progress quickly, and it's often hard to recognize. Sepsis was once commonly known as “blood poisoning.” It was almost always deadly. Today, even with early treatment, sepsis kills about 1 in 5 affected people.
Most sepsis is caused by bacterial infections, but it can also be caused by viral infections, such as COVID-19 or influenza; fungal infections; or noninfectious insults, such as traumatic injury. Normally, the body releases chemical or protein immune mediators into the blood to combat the infection or insult.
If the infection has spread or you have a generalized infection, you may develop other signs and symptoms, such as fever, fatigue, pain, etc. Sometimes however, you may have an infection and not know it, and not have any symptoms.
A small cut could be the cause, or you could develop an infection after a surgical procedure. Sepsis can occur without warning in people who don't know that they have an infection.
"When an infection reaches a certain point, this can happen in a matter of hours." Sepsis usually starts out as an infection in just one part of the body, such as a skin wound or a urinary tract infection, Tracey says.
Sepsis can be caused by any type of infection: bacterial, viral, fungal, or even parasitic. Sepsis prevention is only possible by preventing infections with good and consistent hygiene and avoiding people with infections.
Is sepsis contagious? You can't spread sepsis to other people. However, an infection can lead to sepsis, and you can spread some infections to other people.
At first the infection can lead to a reaction called sepsis. This begins with weakness, chills, and a rapid heart and breathing rate. Left untreated, toxins produced by bacteria can damage the small blood vessels, causing them to leak fluid into the surrounding tissues.
The most common infections that cause sepsis are respiratory (like pneumonia) or urinary tract infections. But sepsis can also develop with influenza (the flu), an infected cut or scrape, or strep throat, to name a few.
When treatment or medical intervention is missing, sepsis is a leading cause of death, more significant than breast cancer, lung cancer, or heart attack. Research shows that the condition can kill an affected person in as little as 12 hours.
The organs more frequently affected are kidneys, liver, lungs, heart, central nervous system, and hematologic system. This multiple organ failure is the hallmark of sepsis and determines patients' course from infection to recovery or death.
The average sepsis-related length of stay during the baseline data collection period was 3.35 days, and the baseline sepsis-related 30-day readmission rate was 188/407 (46.19%).
Weakness or aching muscles. Not passing much (or any) urine. Feeling very hot or cold, chills or shivering. Feeling confused, disoriented, or slurring your speech.
You might continue to have physical and emotional symptoms. These can last for months, or even years, after you had sepsis. These long-term effects are sometimes called post-sepsis syndrome, and can include: feeling very tired and weak, and difficulty sleeping.
