Hepatitis-B is not caused due to the contamination of the water.
Explanation:
Other diseases like Jaundice, Cholera and Typhoid can be caused by the infectious agents of food and water. So other diseases can be caused due to the contamination of the food and the water.
On the other hand Hepatitis-B or liver infection can be caused by the hepatitis B virus. This virus passed from one body to another by blood and other fluid.
