Explanation

Water diseases are grouped by how the water spreads them, each matching a typical example.

Water-borne disease comes from drinking polluted water, as with typhoid.

Water-washed disease comes from a lack of clean water for hygiene, as with trachoma.

Water-based disease comes from contact with water hosting a parasite, as with schistosomiasis.

Water-related disease spreads through insects that breed in water, as with malaria.

Malaria is water-related because its mosquito vector breeds in stagnant water, not by drinking it.
