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 2016, CFRs ranged from 0.0% to 15.8%. CFRs higher than 1% were reported by 22 countries. Of these 22 countries, CFRs higher than 5% were reported in Niger, Zimbabwe and Congo. Globally, the overall CFR was 1.8%. Very high CFRs are 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.
