Waterborne diseases are infections caused by microorganisms such as bacteria, viruses, and parasites that are transmitted through contaminated water. These diseases can be spread through drinking contaminated water, swimming in contaminated water, or consuming food that has been washed or prepared with contaminated water. Examples of waterborne diseases include cholera, typhoid fever, and giardiasis. Preventing waterborne diseases involves ensuring access to clean and safe drinking water, proper sanitation practices, and adequate hygiene measures. Public health authorities and organizations work to monitor and prevent outbreaks of waterborne diseases through water quality testing, sanitation infrastructure improvements, and public education campaigns.
