Broken or ulcerated skin can also provide access to bacteria commonly present in the environment. Invasive medical procedures, including dental work, can introduce bacteria or permit them to accumulate in the body.

People with inefficient immune systems, HIV infection, spinal cord injuries, or blood disorders are at particular risk for sepsis and have a higher death rate (up to 60%); in people who have no underlying chronic disease, the death rate is far lower (about 5%). The growing problem of antibiotic resistance has increased the inciden
