Septicemia, commonly referred to as blood poisoning, is a serious medical condition resulting from the presence of bacteria and their toxins in the bloodstream. It often arises from infections in other parts of the body, such as the lungs, urinary tract, or abdomen. Symptoms can include fever, chills, rapid heart rate, and confusion, and if left untreated, it can lead to severe complications like septic shock and organ failure. Prompt medical treatment, typically involving antibiotics and supportive care, is crucial for a positive outcome.
