International Health Programs

The Department of International Health is organized into four program areas: Global Disease Epidemiology and Control; Health Systems; Human Nutrition; and Social and Behavioral Interventions.

We offer a Master of Science in Public Health (MSPH) and doctoral-level training for research (PhD) in these program areas, as well as a Master of Health Science in Health Economics (MHS). We also offer many continuing education programs online and on campus.

Master of Health Science (MHS) in Global Health Economics

Onsite | Full-Time | 9 months

The MHS in Global Health Economics is a nine-month program that provides students with the skills necessary to use economic tools in the promotion of healthy lifestyles and positive health outcomes. Students will learn how to develop health systems that promote equitable access to care, using applied health cases from around the world.

Master of Science in Public Health (MSPH)

Onsite | Full-Time | 1.5 years - 2 years

The MSPH training program is intended for students who wish to pursue a professional career in the field of public health. Some prior health and/or international experience is preferred.

Doctor of Philosophy (PhD)

Johns Hopkins Researchers Identify Two Distinct Perspectives on Power Imbalances in the Field of Global Health

Connected to decolonizing health, there are current debates in global health concerning power imbalances between the global north and global south. In a series of three articles published in BMJ Global Health, PLOS Global Public Health, and Third World Quarterly, researchers at the Johns Hopkins Bloomberg School of Public Health examined these debates with a focus on understanding differences in how the problems and solutions to redress the power imbalances are understood by different stakeholders.

New Low-Cost Rapid Field Diagnostic Tests for Pathogens ETEC, Shigella, and Cholera May Be the Future in Infectious Disease Outbreak Response and Surveillance

Researchers developed a new, highly sensitive, molecular diagnostic field assay that detects cholera from a stool or water sample in minutes.  The Bloomberg School team has already used similar technology to develop rapid tests for both ETEC and Shigella.
