Cholera belt is a commonly used term to describe the geographic region where cholera is most prevalent. However, there are other terms that can be used interchangeably with cholera belt. One of these is "cholera corridor," which refers to the area stretching from East Africa to the Indian subcontinent that is at highest risk for cholera outbreaks. Another synonym is "cholera-endemic area," which describes regions where cholera is a regular occurrence. Lastly, "cholera hotspots" can also be used to describe the same areas where cholera outbreaks occur frequently. These terms are commonly employed by health organizations and medical professionals to convey the gravity of cholera outbreaks in affected regions.
