What is Public Health?

It is a complicated term that nobody uses and aware of it. Yet, it is a most important area to study if we are talking about any developing and non-developing issue, be it the economy, environment, politics, mental issues, society, media, and things revolving around us. 



Definitions of Public Health:

According to WHO (1988), It refers to both general and private organizations measures to prevent disease, promoting-health, and prolonging life among the country as a whole. Thus the services include provisions of individuals, such as vaccination, behavioral counseling, or healthcare advice.

According to the Centers for Disease Control and Prevention (CDC), It is a system or department or government responsibility. In contrast, all public, private, and non-governmental entities contribute to providing essential services of it with authority. 

Besides, John H. Bryant (2020) added detailed roles of this health plays in the definition given by WHO. It also promotes mental health, sanitation, personal hygiene, control of infectious diseases, and availability of the services where community action plays a vital role in achieving the goals.

  • On the basis of M&E, policymakers design the program to fulfill the needs, such as a family planning program to eradicate poverty. 
  • After analyzing and reforming policies, it is important to ensure that each and every individual has access to get the service. Therefore, The experts study the mind of community people to make the service adaptable, approachable, and affordable, and accessible to them. 

According to the book review (Risk communication and health (public), 1999) of ENRIQUE PERDIGUERO (2001), It is like a big umbrella containing interdisciplinary fields. For instance:
