A guide to public health issues

Our in-depth guide to public health issues lists some of the current public health issues, both in the UK and globally, as well as discussing how they’re prioritised and dealt with by public healthcare professionals. Read on for all you need to know about public health issues.

What is a public health issue? 

Public health involves helping people and communities to stay healthy and protected from threats to their health. Public health initiatives, carried out by public health professionals, include promoting well-being, preventing diseases and mitigating health risks for individuals and their communities.

You may remember these public health campaigns that had a big impact, for example.

Methods for identifying and prioritising public health issues 

As you see, there are multiple public health issues across different communities and countries, impacting millions of people every day. This makes identifying and prioritising a difficult task. In order to prioritise, public health professionals often use a scoring system, taking the following five criteria into account: 

  1. Magnitude of the problem – How many people are affected? Is the public health issue widespread?  

  2. Severity of the problem – Will the public health issue lead to serious illness, disability or death? 

  3. Feasibility of the intervention – Given current resources available, is the public health issue able to be solved or dramatically decreased? 

  4. Government concern – Does tackling the issue have government backing? 

  5. Community concern – Does tackling the issue have community backing? 

Using the above factors and a scoring system, public health professionals will then be able to prioritise the public health issues to address first.

The role of public health professionals in addressing public health issues 

Public health professionals have a significant role in promoting the health of individuals and their communities, by addressing root causes of health issues and implementing feasible strategies to tackle them. Some of their key responsibilities include: 

  • Prevention and education – Developing and implementing resources to educate and empower communities to make the right choices, promoting healthy behaviours. 

  • Monitoring – Using existing data to back decisions on health trends, predicting severity of outbreaks and analysing risks.  

  • Problem-solving – Coming equipped with proposed solutions and developments to policies to improve existing public healthcare. This can either be in the form of gradual roll-out, or emergency response to the likes of natural disasters or infection breakouts such as COVID-19. 

  • Collaboration and partnerships – Collaborating with government agencies, healthcare providers, communities and international partners to address public health challenges collectively and efficiently.
