"Public Health" is the Science and the art of preventing diseases, prolonging life, and promoting physical health and efficiency through organised state effort, by the sanitation of the environment, the control of infections, the education of the individual in principles of personal hygiene, the organisation of medical and nursing service for the early diagnosis and preventive treatment of disease, and the development of the social machinery which will ensure to every individual a standard of living adequate for the maintenance of health. It is the organising of these benefits in such a fashion as to enable every citizen to realise his birthright of health and longevity.
The preservation of the public health is one of the duties devolving upon the State, as a sovereign power. Infact, among all of the objects sought to be secured by Governmental
laws, none is more important than the preservation of the Public Health and an imperative obligation rests upon the civic body through its agencies to take all necessary steps
to promote this object . It is as much for the interest of the civic body that the public health should be preserved as that life should be made secure. The right to the enjoyment
of the health is a subdivision of the right of the personal security, one of the absolute rights of personal.
"Salus populi supreme lax" or the safety of the people is the supreme law, is an ancient Roman maxim. The power to protect the health
and welfare of the people has always been considered an inherent right and duty of any sovereignty. From time immemorial, health has been recognised by Government as the thing
without which life is not worth living. Accordingly, the civic body has always taken such measures as seemed wise to maintain and preserve the health of those subject to its authority.
This is a power inherent in every Government to enact such laws, as will promote the health, Safety, Morale, Order, Comfort and General Welfare of the Society. It means to some
extent the power of promoting public welfare, by restraining and regulating the use of liberty and property.
