Sepsis (/ˈsɛpsɨs/; Greek σῆψις putrefaction and decay) is a potentially fatal whole-body inflammation (a systemic inflammatory response syndrome or SIRS) caused by severe infection. Sepsis can continue even after the infection that caused it is gone. Severe sepsis is sepsis complicated by organ dysfunction. Septic shock is sepsis complicated by a high lactate level or by shock that does not improve after fluid resuscitation. Bacteremia is the presence of viable bacteria in the blood.
