Which of the following is a water-borne disease ?

  • A.Cholera
  • B.Fluorosis
  • C.Influenza
  • D.Tuberculosis

Answer: A

The water-borne disease is cholera.

Cholera is caused by the bacterium Vibrio cholerae and spreads chiefly through drinking water or food contaminated with faeces, causing acute watery diarrhoea.

Fluorosis is caused by excess fluoride in water, a chemical cause rather than a water-borne pathogen. Influenza and tuberculosis are air-borne, spread by droplets from coughing and sneezing.
