Which of the following diseases can be caused by contact with wastewater?

Cholera is a disease that is primarily caused by infection with the bacterium Vibrio cholerae, which is often found in contaminated water supplies, including wastewater. When individuals come into contact with untreated or inadequately treated wastewater that contains this pathogen, they are at risk of developing cholera. The disease is characterized by severe diarrhea and dehydration, which can be life-threatening if not treated promptly.

The other options do not have a direct link to wastewater exposure. Hypertension is primarily related to lifestyle factors such as diet and exercise. Diabetes is a metabolic disorder associated with insulin resistance or deficiency, and asthma is a respiratory condition influenced by genetics and environmental factors, but not specifically associated with exposure to wastewater. Thus, cholera stands out as the disease directly linked to contact with contaminated wastewater.
