Survival rates for a person with both sepsis and pneumonia are not widely available. The death rate for sepsis patients is between 28 and 50 percent, according to the National Institutes of Health. Pneumonia patients with weakened immune systems have a mortality rate of 30 percent, according to MedicineNet.
Sepsis is a serious condition that occurs when the body is fighting an infection, which causes inflammation, as stated by the National Institutes of Health. Sepsis often causes one or two organs to fail. In severe cases, all organs systematically shut down, and death quickly occurs. People with chronic illnesses, such as cancer or AIDS, as well as the elderly are more likely to get sepsis. It is estimated that sepsis affects 1 million Americans per year.
Sepsis can be a direct result of pneumonia, as noted by Sepsis Alliance. Pneumonia is an infection in the lungs that is caused by bacteria, viruses or other organisms, according to the American Lung Association. Fungus causes one type of pneumonia, and inhalation of liquid, food or dust can also lead to pneumonia. People with COPD or congestive heart failure, the very young, the elderly and those with low immune systems are at a higher risk for pneumonia.
