what causes blood infection

Sepsis, also known as blood poisoning, is the body's extreme response to an infection. It can be caused by bacterial, viral, or fungal infections, with bacterial infections being the most common cause. These infections can originate from various parts of the body, such as the lungs, urinary tract, skin, or gastrointestinal tract. Sepsis can develop in anyone, but certain risk factors, such as chronic medical conditions and a weakened immune system, can increase the likelihood of developing sepsis. Without prompt treatment, sepsis can lead to organ failure, tissue damage, and death
