Public health system in promotion of water sanitation and hygiene: an analytical study

Abstract

Public health is defined as the science of preventing disease, prolonging life and improving quality of life through organised efforts, choices of society, communities and individuals which are achieved by promoting healthy lifestyles, prevention, detecting, and responding to diseases. Prevention is carried out by implementation of educational programs, recommending policies, administering services and conducting research. The aim of public health is reached through surveillance of cases and health indicators, promotion of healthy behaviours and limiting the health disparities by promoting healthcare equity, quality and accessibility. The concept of health takes into account physical, psychological, and social well-being as prescribed by World Health Organization that health is not merely the absence of disease or infirmity and more recently, a resource for everyday living. Common initiatives also include promotion of hygiene, education on water and water borne diseases, sanitation, vaccinations, etc.
