The importance of public health courses

Posted: December 15, 2022

Public health courses are a big deal when it comes to making sure people have the knowledge and skills they need to stay healthy and improve their health. 

Public health courses focus on the health of entire populations, not just individual patients. These courses typically cover a wide range of topics, like epidemiology, biostatistics, environmental health, health policy, and global health. People who take these courses might be preparing for careers in healthcare, public policy, or research, or they might just be interested in improving the health and wellbeing of their communities.

Public health courses usually include lectures, discussions, and hands-on learning experiences. For example, you might learn how to collect and analyse data, design and implement health programs, and evaluate the effectiveness of interventions. You might even get to work on real-world projects, like researching the impact of pollution on public health or developing strategies to prevent the spread of infectious diseases.

The benefits of public health courses

One of the best things about public health courses is that they give students a well-rounded understanding of the field. This means you’ll learn about the biological, social, and environmental factors that can affect public health, as well as the different ways to tackle those issues. This kind of comprehensive understanding is crucial for anyone who wants to work in public health, because it lets you approach health challenges from all angles.

Another advantage of public health courses is that they give you the chance to gain some hands-on experience. Many public health programs include fieldwork, where you can put the theories and concepts you’ve learned into practice in real-world settings. This kind of practical experience is super valuable for anyone who wants to build the skills and confidence they need to succeed in the field.

Common public health courses

  • Introduction to public health: This course gives you an overview of the field of public health, including its history, principles and major concepts. You’ll learn about the role of public health in promoting health and preventing disease, and you’ll explore the various disciplines that contribute to the field.
  • Epidemiology: In this course, you’ll learn about the study of the distribution and determinants of health and disease in populations. You’ll learn how to use epidemiological methods to identify risk factors for disease and to evaluate the effectiveness of interventions.
  • Biostatistics: This course covers the use of statistical methods in public health research. You’ll learn how to collect and analyse data, and how to use statistical software to generate tables, graphs and other visualisations.
  • Environmental health: In this course, you’ll learn about the impact of environmental factors on human health. You’ll explore issues like air and water pollution, hazardous waste and climate change, and you’ll learn how to assess and mitigate the risks posed by these factors.


All in all, public health courses are a great investment for anyone who wants to make a positive impact on people’s health. By giving you the knowledge and skills you need to understand and address public health challenges, these courses can help make the world a healthier and more equitable place.

Public health internships and volunteer opportunities 

Public health internships and volunteer opportunities are a great way to gain some hands-on experience and make a positive impact on the world.

Public health internships can be a great way to get your foot in the door and learn from the pros. You’ll have the chance to work alongside public health professionals, gaining valuable experience and skills that will set you up for a career in the field. 

GVI offers a variety of programs focused on public health, including projects focused on clean water, vaccination programs, and maternal and child health. Volunteering with GVI is a great way to gain experience and make a positive impact on the world. Plus, it looks pretty good on a resume.

So, whether you go the internship route, volunteer route, research fellowship route or professional apprenticeship route, getting some experience in public health is a smart move. You’ll gain valuable skills, make a positive impact, and set yourself up for a successful career. Good luck!
