*        Principle of Prevention

 

One of the basic principle of prevention is the community hygine. We can prevent the communicable disease by increasing the public awareness regarding the causes of disease. While treating the infectious disease we normally face the problems like unrecoverable situation of the patient one he suffers from the disease, the treatment taking long time to cure and lastly we have to take care that it does not spread from one person to another. Thus, we can say that prevention is, much better than cure. To prevent the spread of disease we should have proper living condition that is hygienic. There should be proper facility of safe drinking water and clean surroundings. If some one is suffering from the disease we should keep him away from the others, till he gets well properly. The best way to prevent the disease is to immunize the children against various disease, by giving them vaccines. The process of inducing vaccine to the children against certain disease is called vaccination.
