Which bacteria is NOT commonly associated with waterborne illnesses?

Latent viruses are not commonly associated with waterborne illnesses in the same way that the other options are. Cholera, typhoid, and E. Coli are all bacterial pathogens that can cause significant illnesses through contaminated water supplies. Cholera is caused by Vibrio cholerae, which can lead to severe diarrhea and dehydration. Typhoid fever, typically linked to Salmonella Typhi, occurs from consuming contaminated water or food. E. Coli, particularly certain strains like E. coli O157:H7, can also be transmitted via water and cause serious gastrointestinal issues.

Latent viruses, while they can persist in water sources, do not necessarily cause illnesses in the same direct manner as these bacterial infections. Many viral pathogens may be associated with water-related illnesses, but they aren't classified strictly as bacteria and typically require different considerations for their transmission and effects on human health.
