Sepsis, or septicemia, is a life-threatening infection of the bloodstream that affects more than 250,000 people each year and progresses in severity rapidly. If not diagnosed and treated quickly, it can cause lasting tissue damage, organ failure or even death.

Adults 65 and older, children younger than 1 year old, and people with chronic conditions such as diabetes, lung disease, cancer, and kidney disease, are at higher risk of developing infections that can lead to sepsis.
