What Even Is Public Health?
First and foremost, we should discuss what is public health. You probably have heard the term, but no one would blame you for not precisely knowing what it is. By definition, public health is “the art and science dealing with the protection and improvement of community health”.

It involves organized community effort, preventive medicine, and sanitary and social sciences. In other words, public health is the joint effort to improve the quality of life and increase the length of life for communities and society as a whole.
What matters is not just getting healthy after a massive sickness, but also preventing such spread of disease from happening in the first place. It’s about making sure you have suitable conditions for the population to be healthy without needing treatment.
Public health can manifest in various ways. The more obvious examples are measures like vaccines, restrictions and regulations during a pandemic, etc.
Something you may not have thought of as public health are cases like educating teenagers in schools about the potential damage of alcohol, tobacco, or drug substances. It’s setting safety standards in the workplace or establishing healthy nutrition recommendations for school meals.
As you can see, public health can be everywhere around us, even more than you or I could realize.
Public Health in the Professional World
So, now you have a slightly better understanding of what public health is. Great! But what’s next? You want to know what you can do with your online public health degree, once you complete the relevant public health online courses.
The medical field does differ from public health as such, but there is some overlap too. A lot of more direct medical professions are related to public health as well. In most cases, however, for such positions you would need a relevant medical degree, rather than just a public health one.
The first profession that comes to my mind, when talking about public health, is epidemiologist. As stated in the name, these specialists mainly work with epidemics and other contagious diseases. They also conduct a lot of research, analyze data, and communicate with officials in order to implement better public health policies.
Another profession where you would put effort into preventing harm to people is health and safety engineer.
These engineers use their knowledge to identify and evaluate potential risks and hazards in places like an office, a laboratory, a construction site, or an industrial plant. The majority of health and safety engineers are employed either by manufacturers, or by local and state governments.
Public health attorneys also work with local and state governments. They do so in order to establish or improve policies and regulations regarding public health standards.
In case companies violate public health standards, public health attorneys can also function as representatives for the victims. Of course, for this specialized profession, an online public health degree would not be enough - you would need to hold a degree in law as well.
To think on a bigger scale, another great option for a public health specialist would be the environmental sector. Environmental scientists try to protect both the environment and human health, by using their knowledge in natural sciences.
Usually, such specialists collect data, and provide advice to government or industry officials to improve policies and reduce waste. They can sometimes work in a field, helping to clean polluted areas.
Some of these positions do require an equivalent of a masters’ degree in a relevant field. However, public health online classes are still a great way to start your educational journey towards such position. In addition, both edX and Coursera platforms offer programs for a master's degree.

We all are probably tired of hearing about COVID at this point. At the same time, I think this long-term relevant issue has proven to a lot of us how crucial it is to understand epidemics. And how important it is to have such knowledge at the ready before an actual pandemic even happens, instead of scrambling while it’s in full flight.
This program looks into the fundamental scientific principles behind epidemics and pandemics of the 21st century. It analyzes the spread of infectious diseases and discusses public health actions in order to prevent and control such epidemics or pandemics.
On top of lectures from experienced scientists from The University of Hong Kong (HKU), the program includes some panel discussions about certain outbreaks in recent history.
This program has 11 instructors in total - probably the most I have seen in public health online classes, or in online courses overall. 9 of those instructors are from HKU, the others representing Harvard University and London School of Hygiene & Tropical Medicine.
The leading instructor for this program is HKU’s Gabriel M. Leung. In addition to being the dean of the Li Ka Shing Faculty of Medicine in HKU, he has served as Hong Kong’s Under Secretary for Food and Health.
Gabriel also regularly consults various global entities, such as World Health Organization, World Bank, or the Chinese Center for Disease Control and Prevention.
This being one of the public health certificate programs, it actually consists of 4 courses. The courses — Epidemics I through IV — each take either 3 or 5 weeks to complete.
The program is calculated as if spending 2-3 hours per week, but you can set your own pace for studying as you see fit or convenient. Such calculations mean that in total you would spend about 30 to 40 hours on this program.
You can take individual courses, rather than the whole program as well. The program as a whole offers a professional certificate. Individual courses do entail their own course certificates. And if you complete all 4 individual courses, you would still be entitled to the full professional certificate as if completing the full program.
The first course reviews the history of epidemics and factors, leading to an epidemic outbreak. Specifically, the course looks into Ebola and Zika virus outbreaks, and discusses the discovery of microbes during viruses or epidemics.
The second course covers the spread of infectious diseases, with an in-depth review of the epidemiological triangle. The course is finished with the modeling of infectious diseases.
The third course is essentially about disease control. It provides several evaluations of control measures, and explores both vaccines and non-pharmaceutical interventions. This course also includes 2 panel discussions: one on WHO’s actions regarding Ebola, and another one on anti-vaccination.
The fourth and final course of this program is about communicating the disease risk, as well as perceptions of risk and the public not following the advice of health professionals.
The price of this program is $556 (discounted to $500.40 at the moment). If you decide to take individual courses, it will cost you $139 for each. Therefore, making use of the discount for the full program is absolutely a nice catch.
After finishing this program, you’ll have extensive insight into:
- History of epidemics and pandemics
- Models and spreading methods of infectious diseases
- Risk communication

The climate of our world is undeniably changing[1]. With so many sources - both credible and not so much - it’s normal to feel lost or at least confused regarding how it affects our health and what to do about it.
This course comes to your rescue! In this online public health degree course, you will learn various aspects of how climate change influences our health. Starting from the impact on nutrition and infectious diseases, finishing with strategies to relieve this impact.

The course is estimated to take you 7 weeks, with 3-5 hours devoted to it per week. Every corresponds to a different syllabus topic. The first two weeks are about introducing climate change overall and how it affects heat-related illnesses.
The following three weeks cover the impact on water-borne diseases, the effect on crops, and how would human migration look like. The latter would especially focus on island residents, because they would be affected the most by the rising sea levels.
The final two weeks focus on research methods for understanding the climate change impact on health, and what actions to take as a response to climate change.
There are no individual reviews available, but the course has almost 140 thousand students enrolled in it. That sounds like a great crowd for you to join!
The verified track costs $149. This provides a certificate upon completion of the course, as well as makes the course materials available indefinitely after you complete it.
A free audit track option is available as well, but this option would not entail access to any graded assignments, nor the certificate. This means that you would have gained the knowledge, but you wouldn’t actually have the online public health degree you seek.

- What would happen with human migration due to climate change

The WHO defines mental health as “state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community”.
Mental health has definitely been more on the forefront during these last several years and it has been more recognized as an important factor for our physical health[2].
Usually, a mental health ambassador is someone who advocates for the importance of mental health. They share their own experience or function as public speakers, informing others about the importance of mental health and related issues.
This course will provide an online public health degree in mental health, without requiring prior knowledge of mental health or similar aspects. An interest in mental health and in helping others will be enough to start.

This specialization’s aim is to turn you into an effective public health professional. Whether you choose to be either an academic or a practitioner in this field after obtaining your online public health degree, this specialization is meant to prepare you for the role.
Throughout this specialization, you will learn to use principles to articulate public health objectives, and apply appropriate measures to improve public health programs.
This specialization is offered by Imperial College London, where the instructor Dr Richard J Pinder completed his Master’s degree in Public Health. His credentials include a fellowship of the UK Faculty of Public Health, as well as of the Royal College of Physicians of London.
The specialization consists of 4 courses:
You can take any of these public health online classes within the specialization individually or in combination. Bear in mind that courses 2-4 will require the knowledge from the first course.
The specialization comes with a certificate upon completion. You are able to receive certificates for the specific courses you complete. If you complete all 4 courses individually, you will receive the specialization certificate as well.
The first course will teach you to identify and describe various public health challenges in professional and adequate terms.
The second course covers the topics like evaluation of health needs and approaches to public health intelligence. It coaches you on how to conceptualize issues, conduct analysis, and decide on recommendations for the public health sector.
The third installment in the specialization focuses on the behavioral changes within public health practices. It covers risk communication and behavior changes, based on theories from psychology and economics.
The last and final course is all about health protection, as can be guessed from its title. It explains principles of practical microbiology, before diving into more serious topics like vaccines, incident management, or even environmental threats.
Calculating for a pace of 4 hours of learning per week, this specialization would take about 4 months to finish. If you’re interested in these individual public health online courses, each of them would take about 3 weeks to complete.
The courses’ ratings range from 4.5 to 4.9 stars out of 5. Even two out of the four courses had the almost-perfect evaluation of 4.9! Comments depended on each course, but the overall tendency in the reviews was that the covered topics were interesting, and that the courses were easy to understand and very practical.
The prices for specializations on the Coursera platform start at $39 per month, making this specialization total to $156 as the starting point. Very much worth the investment into your online public health degree, and you can even apply for financial aid.

- Articulate public health objectives
- Use behavior change theory to make suggestions for improving public health approaches
- Apply relevant measures for health protection and disease prevention
