Public health as a discipline is really both the science and art of preventing disease, improving health, and prolonging the quality of life within a given society by use of public and private organizations. Overall, it is concerned with threats that are the type that may hurt society as a whole -- epidemics, dangers, social and mental well-being, etc. Modern public health is a multi-disciplinary field that includes medical professionals, statisticians, biologists, ecological and environmental professionals, dental professionals, nutritional experts, veterinarians, engineers, lawyers, sociologists, anthropologists, academics, and the political process itself (Rosen, 1993). Historically, disease vectors, polluted water and pathogens, and lack of sewage without any scientific basis for control or actual understanding of pathogens created public health problems. In the modern world, public health focuses on several levels of health: local/regional, state, national and global -- typically based upon population statistics, demographics and the analysis of disease. Even in modern times, the most predominant issue is communicable diseases that may result epidemic or pandemic proportions, particularly within areas that are unprepared for such outbreaks. In this, the two basic paradigms of public health are: 1) dealing with the preventative side of human health as opposed to focusing on the curative side (prevention and control rather than reaction), and; 2) looking at health from a population level rather than an individual level basis to understand how communities react to health issues overall and what the best means of control might be given the technological and environmental issues at hand (Schneider, 2006).

Overall, public health has historical ties to cultural and religious law, which often attempted to regulate certain behaviors that kept individuals from getting sick (dietary restrictions,...

At times, these laws may have seemed primitive, but were in place prior to the formal study of epidemiology, which was not typical for society until after 1854 when the water from certain wells was linked to cholera, and the germ theory of disease began to glean acceptance (Breslow, 2002).
Public Health at the Local Level- Essentially, the local/regional level of public health is the tactical rather than strategic level of data collection, planning and enforcement of public health needs. Local medical professionals are, by law, required to report certain diseases (hepatitis, STDs, etc.) and that data is used to follow up and report to higher levels to gauge the level of seriousness. At the local level, professionals use educational programs, legal inspections, and integration with the medical community to ensure compliance and prevention. For instance, the inspection and monitoring of local restaurants for cleanliness and adherance to ordinance is the responsibility of local public health officials. Many describe the local health departments as the arms and legs of state and federal agencies -- and most especially to monitor and respond to outbreaks of health related issues (flu, higher than average occurance of disease, etc.). In recent years, this has expanded to the role of helping to prevent pandemic diseases like Type-II diabetes, obesity and chronic hert issues. Many of these issues arise from diet, lifestyle, smoking, alcohol consumption, and behavior, and can be best addressed at the local level on an ongoing preventative means through educational programs and partnerships with schools and the medical community (National Association of County and City Health Officials, 2011).
