Explain the relationship between sanitation and disease.

Sanitation and disease are inversely related to each other. Sanitation involves proper disposal of sewage and refuses from the house and public places. If sanitation is there, no disease will occur, but if sanitation is not there various types of disease will occur and spread. In order to avoid disease, proper sanitation should be maintained.

[Extra information:  Sewage is a liquid containing wastes that is disposed of by households, industrial and agricultural activities in the water.

It is harmful to discharge untreated sewage into rivers or seas because it can pollute the whole source of water. Untreated human excreta can cause a lot of health-related problems. It pollutes water, air, and soil. It can also pollute the groundwater. The polluted water contains disease-causing bacteria that can spread epidemics like cholera, meningitis, typhoid, hepatitis, dysentery, etc. The germs of these types of diseases can easily reach the human population through air, water, or insects and through contaminated food and water and may even lead to the death of several people.]
