Cholera is a disease that is spread in water. Which would be the most practical way to prevent the spread of cholera in a human population?

Cholera spreads when people consume water contaminated with the bacteria, often because human waste enters water supplies. Improving sanitation helps keep waste out of drinking water and is practical for protecting an entire population. Adding antibiotics to water could cause harm and antibiotic resistance, while restricting natural water sources does not ensure safe water.
