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.
Gas gangreneX (also known as clostridial myonecrosis [1]) is a bacterial infection that produces tissue gas in gangrene. This deadly form of gangrene usually is caused by Clostridium perfringens bacteria. About 1,000 cases of gas gangrene are reported yearly in the United States. [2] Myonecrosis is a condition of necrotic damage, specific to ...
However, the most common way to get gas gangrene is through a traumatic injury. In the United States, there is only about 1000 cases of gas gangrene per year. When addressed with adequate care, gas gangrene has a mortality rate of 20-30% but has a mortality rate of 100% if left untreated. [66]
If gas gangrene is left untreated, then it can progress to bacteremia and progress to death. Mortality rates are particularly high for patients that present with shock and those that present with spontaneous gas gangrene infected with C. septicum. [31]
The greatest survival rates are typically seen in patients without pre-existing medical conditions, and with infection localized to the extremities. [4] Gas gangrene proceeds via disruption of blood flow to the infected site, resulting in diminished levels of oxygen and nutrients ultimately causing premature cell death and tissue necrosis. [9]

An estimated 700 million GAS infections occur worldwide each year. While the overall mortality rate for these infections is less than 0.1%, over 650,000 of the cases are severe and invasive, and these cases have a mortality rate of 25%. [4] Early recognition and treatment are critical; diagnostic failure can result in sepsis and death.
Pathogenic bacteria are also the cause of high infant mortality rates in developing countries. [5] A GBD study estimated the global death rates from (33) bacterial pathogens, finding such infections contributed to one in 8 deaths (or ~7.7 million deaths), which could make it the second largest cause of death globally in 2019.
