Sepsis is the body's extreme reaction to an infection and often results in a life-threatening medical emergency. This reaction can be unpredictable and happen very quickly. Sepsis affects the whole body and can lead to tissue damage, organ failure and death if left untreated.
Sepsis is the most common serious complication of infection, and many survivors can suffer long-term complications.
