Cholera case fatality rate
Situation and trends
The reported case fatality rate (CFR) is a measure of the severity of a disease and is defined as the proportion of reported cases of a specified disease or condition which are fatal within a specified time.
With proper and timely treatment, the case fatality rate should remain below 1%. However, many countries report CFRs which are much higher; in 2014, CFRs ranged from 0.01% to 25.71%; CFRs<1% were reported by 8 countries and 12 countries reported CFRs between 1% and 5%. CFR>5% were reported in 4 African countries: Cameroon, Côte d’Ivoire, Guinea Bissau and Kenya. Globally, the overall CFR was 1.17%
CFRs over 30% have been observed among vulnerable groups living in high risk areas. They reflect limited access to proper health care for the most vulnerable people and insufficiencies in health-care systems, including limited capacity of the surveillance system to trigger a timely response.
