Cholera and typhoid fever serve as classic examples of what category of disease.?
Show answer Hide answer
Answer: B. Water Borne Disease
Explanation
Cholera and typhoid fever are typical examples of infectious diseases spread primarily through contaminated water. Pathogens contaminating public water supplies transmit easily to large human populations rapidly. Ingesting water tainted with fecal bacteria causes severe gastrointestinal infection and systemic illness. Waterborne diseases remain a significant public health challenge in regions lacking advanced sanitation infrastructure. Vibrio cholerae and Salmonella typhi are the specific bacterial pathogens responsible for these diseases. Public health agencies focus heavily on water purification and sewage treatment to prevent outbreaks.
Access to clean drinking water is recognized as a fundamental human right essential for disease prevention. Epidemiologists trace contamination sources quickly during waterborne disease outbreaks to protect communities. Boiling drinking water during emergency situations effectively kills harmful bacteria preventing severe illness. Option A is incorrect because airbone diseases spread via respiratory droplets rather than water. Option C is wrong since infection disease is a broad category rather than specifying water transmission. Option D is incorrect because waterborne disease is the accurate classification for cholera and typhoid.
