Risk Factors

What are the risk factors for sepsis? The obvious risk factor is an infection. Any infection, from the tiniest source (a bug bite, a hangnail, etc.) to the more severe (pneumonia, meningitis, and more), can trigger sepsis, which can lead to severe sepsis and septic shock. The infection can be bacterial, viral, fungal, or parasitic. But some people do have a higher risk of developing infections and sepsis than others.

Those at the highest risk of developing sepsis include the very young and the very old (infants and seniors), as well as people with chronic or serious illnesses, such as diabetes and cancer, and those who have an impaired immune system.
