Which disease is NOT caused by waterborne pathogens?

Measles is a viral disease that is primarily transmitted through respiratory droplets and is not associated with waterborne pathogens. This illness is caused by the measles virus, which spreads easily among unvaccinated populations, particularly through close contact with infected individuals or surfaces.

In contrast, cholera, dysentery, and hepatitis are all diseases linked to waterborne pathogens. Cholera is caused by the bacterium Vibrio cholerae and is often contracted through contaminated drinking water. Dysentery, typically referring to an inflammatory disorder of the intestine, can be caused by various pathogens, including bacteria and protozoa, which can also be ingested through contaminated water. Hepatitis A is another example of a waterborne disease, caused by the hepatitis A virus, which can spread through ingesting contaminated water or food.

Understanding the transmission routes of different diseases helps in implementing effective public health strategies, particularly in areas where water quality is compromised. Recognizing that measles is not a waterborne disease highlights the importance of vaccination and airborne transmission prevention in controlling outbreaks.
