Sepsis and septic shock can result from an infection anywhere in the body, including pneumonia. Pneunomia can becommunity-acquired, meaning that a person becomes ill with pneumonia outside of the hospital or a healthcare facility. Pneumonia can also be caused by a healthcare-associated infection (HCAI), which affect 1.7 million hospitalizations in the United States every year. An HCAI is an infection that is pickedup by someone while he or she is in the hospital for a different reason, such as surgery or treatment for an illness, such as cancer.

Sometimes called blood poisoning, sepsis is the body’s often deadly response to infection or injury. Sepsis kills and disables millions and requires early suspicion and rapid treatment for survival.

Worldwide, one-third of people who develop sepsis die. Many who do survive are left with life-changing effects, such as post-traumatic stress disorder (PTSD), chronic pain and fatigue, and organ dysfunction (organs don’t work properly) and/or amputations.

The most common source of infection, among adults, is the lung or lungs.

Definition of Pneumonia

Pneumonia is an infection in the lungs. The infection can be only in one lung, or it can be in both. There are several causes of pneumonia but the most common are:

  • Bacteria
  • Virus
  • Fungus

Left untreated, pneumonia can be deadly. In the days before antibiotics, it’s estimated that about one-third of those who developed bacterial pneumonia died.
