What Does Public Health Mean?
Public health is the study and practice of prolonging life and promoting the overall wellbeing of society. This is done by investigating how to contain and prevent disease and educating communities on healthier ways of living. Public health entails both physical and mental wellbeing. Public health workers search for ways to make cost-effective healthcare available for all.
Safeopedia Explains Public Health
According to the World Health Organization (WHO) public health workers focus on three prime tasks. The first being to assess and monitor at-risk populations and identify with an aim of eradicating possible health risks. The second focus is to articulate policies to solve national and international health problems. Third, to ensure as many people as possible have access to health education, in aims of preventing the spread of disease and viruses. As the world is becoming a "global community," public health workers often have to look at risks globally and not just nationally.
