Question:

Explain the relationship between sanitation and disease.

Answer:

A large number of diseases are caused due to poor sanitation and contaminated drinking water. Poor sanitation leads to the growth of harmful microbes, flies and mosquitoes which are the source of spreading many diseases like cholera, typhoid, polio, meningitis, hepatitis and dysentery. So it’s better to have good sanitation and proper hygiene. Sanitation refers to public health conditions related to clean drinking water and adequate treatment and disposal of human wastes and sewage. Preventing human contact with faeces is part of sanitation, as is hand washing with soap.

Relationship between Sanitation and Diseases:
1. In our country, a large number of people even today do not have sewage 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, the lack of sanitation resulting in the drinking of contaminated water can cause health problems.
2. If sanitation is there, no disease will occur; but if sanitation is not there various types of diseases will occur and spread. So sanitation should be kept to avoid diseases.
