Disease Prevention

Introduction

In order to control or prevent a disease, the cause of that disease, and the manner in which the disease spreads from one person to another must be understood. If the disease is caused by an organism, the life cycle of that organism must be known. Then the knowledge of the cause of the disease, the mode of infection of human beings by the disease and the life cycle of the causative organism can be applied in the control or prevention of the disease.
Several diseases are spread through water. In this article, some water-borne diseases will be identified and measures that can be taken to control or prevent these diseases will be discussed.

Water-borne diseases

How disease is spread

If infected stool passes into a stream, all persons that use the stream water may be at risk. If a cook, who carries cholera bacteria goes to toilet, and handles food without properly washing her hands, those that eat the food may be infected.
