$HALB Blood Sepsis, also known as Blood Poisoning, is an infection of the blood stream. Sepsis is caused when toxin releasing bacteria, such as Staphylococcus, enter the blood. Blood Sepsis is a particularly devastating disease due to the domino-effect of organ shutdown which causes multiple organ failure. Blood Sepsis causes a whole body inflammatory state called Systemic Inflammatory Response Syndrome (SIRS).
