Which of the following is not a water-borne disease?
Dengue
The question asks us to identify which among the given options is not a water-borne disease. Let's analyze the options one by one:
- Typhoid: This is a water-borne disease caused by the bacterium Salmonella enterica, primarily transmitted through contaminated water or food.
- Hepatitis: Specifically, Hepatitis A and E are commonly transmitted through water, making them water-borne diseases. They spread through fecal-oral transmission, often via contaminated water.
- Cholera: This is a well-known water-borne disease caused by the bacterium Vibrio cholerae, typically transmitted through drinking water contaminated with the bacterium.
- Dengue: This is a viral infection transmitted by the bite of infected Aedes mosquitoes, primarily Aedes aegypti. It is not related to water transmission; instead, the mosquito vector breeds in stagnant water but does not spread the disease through water directly.
Based on the analysis above, Dengue is not a water-borne disease as it is transmitted through mosquitoes and not through direct contact with contaminated water.
Hence, the correct answer is Dengue.
