An Insight into Public Health

GREETINGS…… ASSALAMUALAIKUM.
This is an introduction for all my respected viewers and readers. I assume we all have an idea on our own about Public Health. But really, what is Public Health by exact definitions?
Hurmmmmmmm…. Interested? Then allow me the honor to share a little bit of my knowledge about the facts and fun of PUBLIC HEALTH.

In 1920, Winslow stated that "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". It is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health is typically divided into epidemiology, biostatistics and health services. Environmental, social, occupational health, and behavioral are other important subfields.

The focus of Public Health intervention are primarily directed towards prevention rather than treating a disease through surveillance of cases and the promotion of healthy behaviors. In addition to these activities, in many cases treating a disease may be vital to preventing it in others, such as during an outbreak of an infectious disease. Hand washing, vaccination programs and distribution of condoms are all examples of public health measures. So basically, everything that we saw on television or other mass medias are all linked back to Public Health.

The goal of public health is to improve lives through the prevention and treatment of disease. The United Nation’s World Health Organization defines health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."

Now for the big question, what does Public Health has to do with healthcare? Actually, as well as seeking to improve population health through the implementation of specific population-level interventions, public health professionals also seek to improve population health by improving the contribution of medical care to life extension and quality of life. Such improvements could be identified by assessing what need for health services existed within the population, and also by checking all of these followings,
1. Assessing current services
2. Ascertaining requirements as expressed by professionals, public and other stakeholders
3. Identifying the most appropriate interventions
4. Considering the effect on resources
5. Agreeing and implementing any necessary changes

So that is basically all u need to know about Public Health in general so that you will have a better understanding about the general idea of Public Health, and why it existed in the beginning. Thank you for your kindness of lending me your most precious time, tune in next time for my eagerly anticipated topic, mHealth.
