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 2015, CFRs ranged from 0.0% to 11.7%; CFRs>1% were reported by 15 countries. Of these 15 countries, CFR>5% were reported in Myanmar and Niger. Globally, the overall CFR was 0.8%

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.
