Solution
Germs of cholera spread through the faeces of a patient. They pass through water or food. If such contaminated water is used for drinking, others may get the infection of cholera. Therefore, during an epidemic of cholera, water should be boiled. Boiling destroys the germs in the water, and therefore we are protected against the germs. In order to keep our health safe, we should drink boiled water.
