The definition of public health has changed throughout the years. Additionally, people define public health from his or her perspective. However, each definition covers a vast range of approaches, concepts, and sectors. According to Dr. Richard Riegelman, public health is “The totality of all evidence-based public and private efforts that preserve and promote health and prevent disease, disability, and death.” Public health takes into consideration a large canvas representing social, economic, and environmental elements while examining many concerns.

In the last decade people have become increasingly aware of threats to their physical and mental health due to environmental factors, terrorist threats, costs and availability of quality health care, and pandemics such as SARS, AIDS, and H1N1. It has become more apparent to not merely focus on individual care, but to also consider the overall population.

Putting forward public health advances, practices, policies is an ongoing process. Present day approaches entail what is known as the evidence-based approach. First, problems are identified; the cause or etiology of a problem is determined followed by recommendations to eliminate or curtail the health concern; finally, implementation or intervention options are considered and administered. The preceding steps may appear as a simple formula; however it is an ongoing, recycling, complicated process.

Once more, there are many definitions for public health. Nonetheless, the overall consensus is that public health is instrumental in preventing disease and promoting quality health. It is also responsible for providing policies and research to professionals who use this information to educate the public, as well as reduce health care costs, provide accessibility to quality care facilities, and protect the public from harm. For instance, state, local, and city departments implement educational campaigns of the proper way to wash hands to deter the spread of viruses.
