Explanation :
Cholera, caused by the bacterium Vibrio cholerae, can be both epidemic and endemic. Epidemic cholera refers to sudden outbreaks affecting large populations, often due to contaminated water. Endemic cholera signifies the continuous, stable presence of the disease in specific regions, indicating a persistent, albeit lower, level of infection over time.
