Risk Factors

What are the risk factors for sepsis and septic shock? 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.
