Sepsis is a life-threatening condition that occurs when the body has an extreme reaction to an infection. Like falling dominoes, sepsis triggers a rapid escalation of problems that can lead to tissue damage, organ failure and death if not treated in time.
Each year, about 1.7 million people in the United States develop sepsis, and approximately 350,000 of those people die, according to statistics from the Centers for Disease Control and Prevention. Among patients who die in a hospital, one in three has sepsis, making it a top cause of death in the intensive care unit.
Diagnosing and treating sepsis can be challenging, in part because its symptoms can be vague or mistaken for other health problems.
