Public health is an important aspect of healthy communities, and the people who carry out this work make an important contribution to individuals, families and communities’ health & quality of life. However, public health is not perceived as the most popular career opportunity. This is because even the most remarkable achievements in public health were not sufficiently appreciated. For example, the global progress in reducing under-5 deaths from 12.6 million in 1990 to 5.2 million in 2019 was the conscious result of the public health sector, but is under appreciated by the general public. It’s not surprising that jobs in public health are less known and respected because public health practitioners aren’t acknowledged and valued for their contributions and services. Because the field is so hard to describe, it becomes underestimated. On one level, it might refer to treatment that is offered in the community rather than in a hospital setting or it might be the efforts to avoid epidemics and enhance the health of an entire country.

Although public health may bring up thoughts of government medical hospitals or public awareness campaigns promoting healthy living, the field is far broader. Instead, public health experts are involved in everything from disease detection to public policy development to assisting immigrants with their integration into new communities. A pandemic like COVID-19 has been experienced by the majority of the world more than ever before, and there will be no scarcity of need for well-trained public health workers.

The functional features of public health are distinguished by the presence of a distinct team of individuals who set public health practitioners apart from those in other areas. Public health is carried out by physicians, nurses, dentists, social workers, nutritionists, anthropologists, pharmacists, economists, managers, lawyers, and people from many other professions and fields. As a result, public health encompasses a broad range of professions. These again ranges from epidemiologists who help prevent disease to more unusual ones like marketing professionals who work on wellness initiatives or public health law enforcement officers who focus on substance misuse prevention. This multi-disciplinary workforce allows public health to use an inter-disciplinary approach in identifying and solving community problems, which are trademarks of public health practise.

The Masters in Public Health (MPH) is the most common graduate degree earned by those working in this field, and at minimum, includes these six areas of study: Research, Global Health, Epidemiology, Environmental Health Sciences, Health Systems & Services, Social & Behavioral Science and Biostatistics.

While there are many people working in the domains of public health, there are considerably fewer who have obtained their degrees in these fields. As a vast field, public health can lead to a variety of job options. For example, public health graduates with a combination of research and communication abilities are good candidates for planning projects and initiatives for a variety of employers. However, as previously said, they all begin with the appropriate degree. MPH can train students for jobs in a range of industries, in addition to traditional ones. In future international battles of disease prevention, environmental concerns, and bio-terrorism, these public health experts will be on the front lines of defence.
