Global Health with Greg Martin

Epidemiology underpins everything we do in public health and global health. Epidemiology is more than just research methods and qualitative and quantitative study design. Its about understanding the distribution of states of health and the exposures that cause them. And its about causation. Epidemiology is about population health, outbreaks, pandemics, epidemics. And of course its includes non-communicable diseases too. This channel posts global health and public health teaching videos and videos about how to find the right job in global health.

Pandemic preparedness is a hot topic. Why might the next pandemic be much worse that the COVID-19 pandemic? To answer that question, we need to consider the epidemiological factors like disease transmission, immunological response and virus mutation. We also need to understand R0, Case Fatality Rate, the incubation and infectivity periods and other factors that feed into how bad a pandemic might get. Understanding the epidemiology will help us plan a public health and global health strategy.

Dr Greg Martin talks about the sensitivity and specificity of diagnostic tools used in global health programs. This forms part of the epidemiology series. Global health (and public health) is truly multidisciplinary and leans on epidemiology, health economics, health policy, statistics, ethics, demography.... the list goes on and on. This YouTube channel is here to provide you with some teaching and information on these topics. I've also posted some videos on how to find work in the global health space and how to raise money or get a grant for your projects. Please feel free to leave comments and questions - I'll respond to all of them (we'll, I'll try to at least). Feel free to make suggestions as to future content for the channel.

Incidence and prevalence use in Public Health as a measure of the burden of disease in community or country. We also sometimes refer to point prevalence and period prevalence. These are basic concepts in epidemiology that help plan health interventions and measure the impact of public health actions.

Universal Health Coverage is about providing healthcare to people without pushing people into poverty. It's an exciting public health and global health tool. Countries that implement universal health coverage provide better healthcare at lower costs (the health economics evidence is clear).

You probably know a couple who both work full time to support their children, but even with their dual incomes, they’re finding it more and more difficult to afford health insurance. Everyday incidents like sports injuries, asthma, and blood pressure, combined with their anxiety over rising premiums, are turning their American dream into sleepless nights. Why can’t people catch a break? It wasn’t always this way!

If you're about to or have started a Master of Public Health degree or MSc Public Health, then this video will talk you through what you need to do to get the most out of the experience. Public Health includes health promotion, health economics, health policy and many other subjects. The most important one however is epidemiology. As you do your Masters in Public Health, focus on epidemiology if you can. Your MPH is an excellent opportunity to network with other public health professionals and people involved with global health issues. Most importantly however - enjoy your MPH.

I f you are about to start or thinking of doing a Master of Public Health degree, then this video will tell you what you should expect from the program. An MPH is an excellent stepping stone into a public health or global health career. If you're wanting to work on local public health problems or international public health, then doing an MPH is usually a requirement. In your Masters in Public Health or an MSc in Public Health you'll learn about epidemiology, statistics, health policy, health economics and more. These subjects will then be applied to domains of public health including health protection, health promotion, health intelligence and health services improvement. It's an exciting time. Enjoy being a student.

In this video, Dr Greg Martin describes how randomized control trials work and how they deal with confounding variables. This is episode three in a series of videos looking at epidemiology, research methods and study design in the context of global health.

In this video, Dr Greg Martin provides an introduction to research methods, methedology and study design. Specifically he takes a look at qualitative and quantitative research methods including case control studies, cohort studies, observational research etc. Global health (and public health) is truly multidisciplinary and leans on epidemiology, health economics, health policy, statistics, ethics, demography.... the list goes on and on.

In this short video, Dr Greg Martin discusses Case Control and Cohort studies. He compares the strengthes of each study design and descibes when each of them would be a preferred research method.

R0 (the basic reproductive number) tells us more than just how many people will be infected in a totally susceptible population. It can be used to calculate the how much vaccine coverage is needed to get to herd immunity. As COVID-19 continues to spread, the development of a vaccine that will be used to immunise people is being talked about. A Coronavirus vaccine is likely to give immunity for about a year. Although we'll only know for sure once vaccination programmes are started. R0, which is pronounced R naught, can be used to calculated how many people need to be immunised to end the pandemic. This video should be of interest to pubic health doctors, epidemiologists and people interested in global health.

Determining causality isn't easy. Correlation doesn't mean causation. And yet where we see a strong correlation between an exposure and an outcome, we need to be able to determine if there is a cause and effect relationship. Public Health professionals and epidemiologists have typically use the Bradford Hill criteria to establish causality. I don't like the Bradford Hill criteria. Instead I advocate for a process of exclusion (exclude chance, bias, confounding, reverse causation and fraud).
