Which of the following is a water borne disease ?

Question

Accepted Answer

Hepatitis is a waterborne disease, which means it can be transmitted through contaminated water. Specifically, Hepatitis A and E are known to spread through the consumption of water or food that has been contaminated with the feces of an infected person. This is common in areas with poor sanitation and inadequate water treatment facilities. The virus can survive in water for extended periods, making it a significant public health concern in regions where clean water is not readily available.

Now, let's examine why the other options are incorrect:

1. **Diphtheria**: This is a bacterial infection caused by Corynebacterium diphtheriae. It spreads through respiratory droplets from coughing or sneezing of an infected person, not through water. Therefore, it is not classified as a waterborne disease.

2. **Tetanus**: Tetanus is caused by the bacterium Clostridium tetani, which is commonly found in soil, dust, and animal feces. It enters the body through wounds or cuts, especially those contaminated with soil or manure. Tetanus is not transmitted through water, so it is not a waterborne disease.

3. **Cough**: Coughing is a symptom rather than a disease itself and can be caused by various conditions, including respiratory infections like the common cold or flu. These infections are typically spread through airborne droplets, not through water. Therefore, cough is not considered a waterborne disease.

In conclusion, Hepatitis is the correct answer as it is a disease that can be transmitted through contaminated water, unlike the other options listed.
