The most ordinary type of blood infection is known as sepsis, "a serious problem of septicemia. Sepsis is when inflammation throughout the body occurs. This inflammation can cause blood clots and block oxygen from reaching vital organs, resulting in organ failure. The National Institutes of Health (NIH) estimates that over 1 million Americans get severe sepsis each year. Between 28 to 50% of these patients may die from the condition. When the inflammation occurs with extremely low blood pressure, it’s called septic shock. Septic shock is fatal in many cases.
