Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death. A CFR is generally expressed as a percentage. It is a measure of disease lethality, and thus may change with different treatments. [1] CFRs are most often used for with discrete, limited-time courses, such as acute infections.
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4] [7] This initial stage of sepsis is followed by suppression of the immune system. [8] Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. [1]
The SOFA scoring system is useful in predicting the clinical outcomes of critically ill patients. [8] According to an observational study at an Intensive Care Unit (ICU) in Belgium, the mortality rate is at least 50% when the score is increased, regardless of initial score, in the first 96 hours of admission, 27% to 35% if the score remains unchanged, and less than 27% if the score is reduced.

Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
The Sepsis Six is the name given to a bundle of medical therapies designed to reduce mortality in patients with sepsis. [citation needed] Drawn from international guidelines that emerged from the Surviving Sepsis Campaign [1] [2] the Sepsis Six was developed by The UK Sepsis Trust. [3] (Daniels, Nutbeam, Laver) in 2006 as a practical tool to ...
In cases where diagnosis and appropriate treatment are delayed, the case fatality rate approaches 50%. Recovery is possible with appropriate, timely management of the illness. Mineralocorticoid and glucocorticoid treatments may be necessary depending on the recovering patient's electrolyte status and response to treatment.
The infections are typically characterized by either meningitis or sepsis, and are caused by encapsulated organisms including Streptococcus pneumoniae. [3] It is a medical emergency and requires immediate treatment. Death has been reported to occur within 12 hours. [4]
