(HealthDay News) -- Sepsis is the body's deadly response to an infection that lurks in the tissues and organs.
More than 1.5 million people in the United States get sepsis each year, and at least 250,000 die from it, the Centers for Disease Control and Prevention says.
While anyone can develop sepsis, it typically occurs in people aged 65 or older, people with weakened immune systems and among people with chronic health conditions.
Fever, shivering or feeling very cold.
