Promoting development , Strengthening health systems

The focus of a public health intervention is to prevent and manage diseases, injuries and other health conditions through surveillance of cases and the promotion of healthy behaviors, communities and environments.
Many diseases are preventable through simple, non-medical methods.
For example, research has shown that the simple act of hand washing with soap can prevent many contagious diseases.[4] In other cases, treating a disease or controlling a pathogen can be vital to preventing its spread to others, such as during an outbreak of infectious disease, or contamination of food or water supplies.
Public health communications programs, vaccination programs, and distribution of condoms are examples of common public health measures.
Measures such as these have contributed greatly to the health of populations and increases in life expectancy.
Public health plays an important role in disease prevention efforts in both the developing world and in developed countries, through local health systems and non-governmental organizations.
The World Health Organization (WHO) is the international agency that coordinates and acts on global public health issues.
Most countries have their own government public health agencies, sometimes known as ministries of health, to respond to domestic health issues.
For example in the United States, the front line of public health initiatives are state and local health departments.
The United States Public Health Service (PHS), led by the Surgeon General of the United States, and the Centers for Disease Control and Prevention, headquartered in Atlanta, are involved with several international health activities, in addition to their national duties.
In Canada, the Public Health Agency of Canada is the national agency responsible for public health, emergency preparedness and response, and infectious and chronic disease control and prevention.
The Public health system in India is managed by the Ministry of Health & Family Welfare of the government of India with state owned health care facilities.
There is a vast discrepancy in access to health care and public health initiatives between developed nations and developing nations.
In the developing world, public health infrastructures are still forming.
There may not be enough trained health workers or monetary resources to provide even a basic level of medical care and disease prevention.[5] As a result, a large majority of disease and mortality in the developing world results from and contributes to extreme poverty.
For example, many African governments spend less than US$10 per person per year on health care, while, in the United States, the federal government spent approximately US$4,500 per capita in2000.
However, expenditures on health care should not be confused with spending on public health.
Public health measures may not generally be considered "health care" in the strictest sense.
For example, mandating the use of seat belts in cars can save countless lives and contribute to the health of a population, but typically money spent enforcing this rule would not count as money spent on health care.

I think that public healthcare needs to also stimulate people to take care of their health because not everyone does it, and that's pretty bad. I believe that taking supplements like Dermal Repair Complex is not that hard, and it's way better than not doing anything at all to support your health, so it needs to be done.

Thanks for your answer. Public health as mentioned is cover the preventive side while clinical side cover the management of admitted ill patients. Role of Public Health is very much important in a sense to control the disease through prevention.It also strengthen the health system by creating awareness through different communications,it help for the development of health policies. Further the load on the hospitals will be less. The most important is to save the life of people and provide the health services at the door step of the community.
