Explanation

Water-borne diseases spread by drinking contaminated water, as with cholera.

Water-washed diseases spread through a lack of hygiene water, as with trachoma.

Water-based diseases involve an aquatic host, as with schistosomiasis.

Water-related diseases spread through insect vectors bred in water, as with malaria.

Matching gives water-borne-cholera, water-washed-trachoma, water-based-schistosomiasis, water-related-malaria.

This classification guides which water intervention prevents each disease.
