Explain the relationship between sanitation and disease.

Explanation

Sanitation and disease are related to each other as lack of sanitation can cause diseases.
In our country, a large number of people even today do not have sewerage facilities and thus defecate in open fields, railway tracks, etc. The untreated human excreta thus pollute soil and water sources including the underground water. When this contaminated water is used for drinking, it can cause diseases such as cholera, typhoid, hepatitis, dysentery, etc. which may even lead to death. Therefore, lack of sanitation resulting in drinking of contaminated water can cause health problems.
