Top 7 In-demand careers in public health

The public health industry evolves and expands like any other. This list includes seven in-demand public health careers:

1. Epidemiologist

The work of an epidemiologist focuses on determining the causes and trends of diseases and injuries that occur within communities. Public health policy can then be improved, and future outbreaks can be avoided with the use of this information.

You will be essential in recognising and containing pandemics as an epidemiologist. As a result, their work is more important than it has ever been. You can save lives while also advancing societal well-being in this way.

2. Public health educator

Community education is vital in the field of public health. Teaching communities the value of healthy behaviours and how to implement them is the mission of public health educators. This role ensures access to healthcare and prevents disease spread.

As a public health educator, you will have a direct impact on helping individuals live healthier lives and promoting well-being within your community.

3. Public health researcher

Public health researchers play a crucial role in our understanding of health and disease. They plan and perform research to study, collect, and draw findings regarding illnesses and health. These findings can lead to new drugs, treatments, and health guidelines.

As a researcher, you might be the first to identify a medical discovery that saves or significantly enhances the lives of countless people. Just picture yourself as the one who discovers a novel approach to either treat or prevent a disease.

4. Public health nurse

Nurses also play a vital role in the world of public health. These superheroes in scrubs don't just work in hospitals. They can be found in many different settings, helping people stay healthy and providing essential care when they're sick. 

Public health nurses specialise in illness prevention and community health. They might work in schools to teach kids about healthy habits, or they can be involved in large-scale health policy planning. 

5. Biostatistician

Biostatisticians are the maths whizzes of the public health world. They use their number-crunching skills to understand health trends and patterns. They can determine what's causing illness, where diseases are spreading, and how to stop them by analysing study and survey data.

Important decisions on where to deploy vaccines or how to better health services are made easier by using this data by health officials. So, this might be the right career for you if you have a knack for numbers and want to have a large impact.

6. NGO managers

Non-governmental organisation managers also impact public health. This field is ideal for those who wish to make a difference. As an NGO manager, you'll work on key health issues, develop public health programs, and lead teams to execute these programs.

Policy advisors are the masterminds behind public health policies. These professionals research, analyse, and provide recommendations for policymakers to improve public health outcomes.

Working as a policy advisor allows you to influence and shape healthcare policies at local, national, or even global levels. Health equity, disease prevention, and healthcare access advice can improve society.

What is the role of a scientific advisor?

To offer the evidence.

According to the Oxford Centre for Evidence-based Medicine, they state; scientists do not present what they think; they offer the evidence, its strengths and weaknesses and possible interpretations. 

There may be many interpretations. Therefore, the scientific process entails testing these and eliminating the unlikely ones one by one until you are left with the most likely or the least falsifiable- what you would call “following the science.”

Your interpretation may not be the truth, but it’s the one with the least uncertainty, and it allows you to weigh the known benefits and risks as dictated by the precautionary principle.

Then, if asked, you should give a view of why, on a balance of probabilities, interpretation A is more likely than B or C, bearing in mind the methodological quality of the original studies. If there is genuine uncertainty and you do not know if A Is better than B or C, then your advice should reflect this. 

To ensure that advice is reliable, we must follow the scientific method, which requires testing hypotheses and acknowledging uncertainties. Any advice that fails to reflect these principles is misguided.
