Any type of infection can lead to sepsis. This includes bacterial, viral or fungal infections. Those that more commonly cause sepsis include infections of:
•Lungs, such as pneumonia.
•Kidney, bladder and other parts of the urinary system.
•Digestive system.
•Bloodstream.
•Catheter sites.
Some factors that increase the risk infection will lead to sepsis include:
•People over age 65.
•Infancy.
•People with lower immune response, such as those being treated for cancer or people with human immunodeficiency virus (HIV).
•People with chronic diseases, such as diabetes, kidney disease or chronic obstructive pulmonary disease (COPD).
•Admission to intensive care unit or longer hospital stays.
As sepsis worsens, vital organs, such as the brain, heart and kidneys, don't get as much blood as they should. Sepsis may cause atypical blood clotting. The resulting small clots or burst blood vessels may damage or destroy tissues.
Most people recover from mild sepsis, but the mortality rate for septic shock is about 30% to 40%. Also, an episode of severe sepsis raises the risk for future infections.
