Which disease can be transferred to a new victim through contaminated water?

Typhoid fever is directly associated with contaminated water sources and is primarily caused by the bacterium Salmonella Typhi. This disease spreads when individuals consume water or food contaminated with the feces of an infected person. The connection to water contamination is crucial, as outbreaks often occur in areas with inadequate sanitation and unsafe drinking water.

In contrast, diphtheria is transmitted through respiratory droplets rather than water. Gonorrhea is a sexually transmitted infection, and while it's concerned with personal contact and not water, malaria is caused by a parasite transmitted through the bite of infected mosquitoes, not through water. Hence, typhoid is the only disease in the list that is specifically linked to water contamination and can be transferred to individuals through that medium.
