Which of the following is a waterborne disease?

Hepatitis is considered a waterborne disease because it can be transmitted through contaminated water. Specifically, Hepatitis A and E viruses, for instance, can spread when a person ingests food or water that has been contaminated by fecal matter containing the virus. This is particularly a concern in areas with inadequate sanitation or where water quality is compromised.

In contrast, hypertension, diabetes, and asthma are primarily chronic conditions influenced by lifestyle, genetics, and environmental factors, rather than by pathogens in water. While poor water quality can contribute to health problems more broadly, these conditions do not have direct links to waterborne transmission like hepatitis does. Therefore, understanding the transmission routes for diseases is crucial in the context of public health and water treatment to prevent outbreaks and protect communities.
