Public Health

Public health in its very core means to market health and quality of life by preventing and controlling disease, injury, and disability. Public Health’s mission is to make the conditions within which individuals are often healthy. Public health practitioners are mainly nurses and doctors running screening programmes, local residents campaigning for better housing, engineers drilling bore holes to supply clean water for villagers during a developing country. The target of public health is on inhabitants and sections of people. This is a really different objective from the day-to-day focus of most health professionals on the health problems of people. Examining the health of a population and the threats it faces is the basis for public health. Public health focuses to improve the quality of life through inhibiting and treatment of disease, including mental health. Public Health shapes the context within which individuals and communities are often safe and healthy. As a whole, public health is about protecting the health of entire populations. These populations are often as little as an area neighborhood, or as huge as a full country or region of the planet. The essential services for public health include: monitoring heath status, diagnosing and investigating health problems, informing and educating, mobilizing communities to address health problems, developing policies and plans, enforcing laws and regulations, linking people to needed health services, assuring a competent health services workforce, evaluating health services and conducting research for new innovations. The core functions of public health are evaluation, policy evolution and promise. Assessment includes surveillance of disease/injury, monitoring trends; analyzing causes; and identifying needs. Policy Development defines broad community involvement; promote scientific basis of decision-making; strategic approach; development of comprehensive public health policies.
