a. infectious diseases

Contaminated water transmits pathogens (cholera, typhoid, dysentery, diarrheal diseases) and causes far more immediate illness and deaths worldwide than the other effects. Algal blooms, toxic bioaccumulation, and low oxygen mainly harm ecosystems and seafood safety, but waterborne infectious disease is the largest direct human health impact.
