Your guide to a public health career: what you need to know

Choosing a career in today’s world is about making an impact. If you’re someone who wants to make some real changes, then a career in public health might be exactly what you’re looking for. 

At the University of East London (UEL), we’re proud to offer students the opportunity to gain real-world skills and experience through our specialised public health courses, designed to prepare you for the challenges and rewards of this essential sector.

What does a career in public health look like?

Public health is a field dedicated to improving the health and well-being of populations, not just individuals. While doctors treat patients one-on-one, public health professionals look at the bigger picture: preventing disease, promoting healthy lifestyles, and addressing health inequalities across regions and demographics. The aim is to protect health before illness even occurs.

A public health career spans everything from vaccination programmes and pandemic preparedness to tackling obesity, mental health, and environmental risks. Professionals work across research, government, policy, education, and community outreach, often with long-term societal impact.

What do public health professionals do?

Public health professionals wear many hats depending on their roles. Some analyse health data to track disease outbreaks, while others design public health campaigns to reduce smoking or improve nutrition in underserved areas. Many work closely with governments, NGOs, or community leaders to deliver policies and interventions that address local or global health needs.

For example, during the COVID-19 pandemic, epidemiologists and public health officials were on the frontline of decision-making, guiding lockdown measures, vaccine distribution, and public messaging. These are the people behind the scenes ensuring that healthcare systems remain proactive, not just reactive.

Is it a good career?

Absolutely, and it’s more in demand than ever. According to the UK Office for National Statistics (ONS), health and social care remains the largest employment sector in the UK, with over 4.3 million workers (ONS, 2023). The World Health Organisation (WHO) estimates that the global public health workforce will need to grow by 13 per cent by 2030 to meet rising health demands. 

The job market for public health is not only growing but also diversifying across sectors, including digital health, sustainability, and international development. This makes a public health career path both stable and future-proof. It also comes with high levels of personal satisfaction, as professionals know their work has a direct and lasting social impact.

What are the benefits of working in public health?

One of the biggest draws of a career in public health is the diversity of opportunities. You can work locally or globally, in public or private sectors, and across a wide range of roles—from research and statistics to community outreach and policymaking. There’s also room for mobility: a strong foundation in public health can open doors in government, academia, nonprofits, and international organisations like the WHO or Médecins Sans Frontières.

What’s the best degree for a career in public health?

An undergraduate degree, such as a BSc (Hons) Public Health, provides a comprehensive introduction and is ideal for starting your journey. A Master of Public Health (MPH) or MSc Public Health is more advanced and suitable for those looking to specialise or enter leadership roles.

According to Prospects UK, public health graduates typically enter careers in health promotion, health education, research, and policy development. Over 90 per cent of UK public health graduates are employed or in further study within six months of graduation.

Is public health more science or management?

The answer is both. Public health blends evidence-based science with policy-making, programme design, and even behavioural economics. You’ll need a strong grasp of scientific thinking, but you’ll also apply that knowledge in ways that influence laws, budgets, and community outcomes. If you enjoy both logic and leadership, this balance can be very rewarding.

So, is a public health career right for you?

If you're interested in improving lives, solving complex challenges, and working in a field with global relevance, then yes, public health could be an excellent fit. It offers more than just a job. It offers a purpose. With the right public health course, you can build a career that’s not only intellectually fulfilling but also socially transformative.
