Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4] [7] This initial stage of sepsis is followed by suppression of the immune system. [8] Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. [1]
“Sepsis usually begins with an infection, for example in the chest, skin, urine or meningitis, but in the early stages symptoms can be vague and hard even for doctors and nurses to recognise.
When sepsis occurs, it can cause inflammation and cause blood clotting around the body, if it does not get treated, it can result in death, organ failure and tissue damage, CDC says.
It is a phenomenon most commonly witnessed in sepsis, and less frequently in autoimmune diseases, differentiation syndrome, engraftment syndrome, hemophagocytic lymphohistiocytosis, the ovarian hyperstimulation syndrome, viral hemorrhagic fevers, and snakebite and ricin poisoning. [1]

Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
Early symptoms include fever and flu-like symptoms. [2] A few days later the skin begins to blister and peel forming painful raw areas. [2] Mucous membranes, such as the mouth, are also typically involved. [2] Complications include dehydration, sepsis, pneumonia, and multiple organ failure. [2]
Bacteremia can have several important health consequences. Immune responses to the bacteria can cause sepsis and septic shock, which, particularly if severe sepsis and then septic shock occurs, have high mortality rates, especially if not treated quickly (though, if treated early, currently mild sepsis can usually be dealt with successfully).
