In brief: Terminology
Bacteremia describes the presence of bacteria in the bloodstream - this may or may not make you ill (e.
g. You are briefly bacteremic after brushing your teeth, but your body clears it). Septicemia is multiplication of bacteria in the blood (almost always associated with illness... But not always), and sepsis is the systemic response to infection.
