Global Health - The Essentials

Learn how the burden of disease quantifies a disease's impact, guiding public health planning and policy. Explore measurement methodologies and global trends from the global burden of disease study (2000–2016).

Measure global burden of disease using prevalence, incidence, mortality, and morbidity. Compare years of life lost, years lived with disability, and disability-adjusted life years, plus quality-adjusted life years.

Explore the global burden of disease using the online tool to view maps and treemaps, compare causes, risk factors, and DALYs across ages, genders, and locations.

Explains the demographic transition from traditional to modern societies, showing how death rates fall with improved sanitation and food, while birth rates eventually decline due to contraception and women's education.

Explore how the global burden of disease shifted from infectious to non-communicable diseases since 1990, with regional patterns and implications for health systems, policy, and research.

Evaluate the global burden of disease, learn how to measure it with an online tool to explore trends, and consider the implications of a changing burden while testing yourself.

Explore the central role of infectious diseases in global health, compare them with chronic diseases, and examine prevention, detection, and international response to outbreaks such as Ebola.

Explore HIV and AIDS, their transmission routes, rapid detection tests for diagnosis, and how antiretroviral therapies control viral replication and reduce transmission amid testing and access challenges.

Tuberculosis, caused by Mycobacterium tuberculosis, spreads via droplets and coexists with HIV as a co-infection; latent TB can become active, diagnosed by sputum tests, with six months of four antibiotics.

Explore malaria, a preventable and curable parasitic disease spread by female mosquitoes, with prevention through indoor residual spraying and insecticide nets, fast diagnosis, and artemisinin based combination therapy.

Explore how local cultural practices, weak health systems, and international coordination shaped the Ebola outbreak response using a geographical framework that moves from local to global.

Explore HIV/AIDS, tuberculosis, and malaria—their transmission, at-risk groups, and global burden. Assess prevention and treatment strategies, future challenges, and Bala outbreak lessons using a geographical framework for outbreak response.

Explore the major determinants framework for global health, examining social, behavioral, cultural, geopolitical, and environmental determinants and how they shape health outcomes and policy decisions.

Examine how social determinants of health (unemployment, income, housing, education, and social exclusion) shape health status, access to water and services, and inequalities across developing and western contexts.

Explore behavioral determinants—lifestyle risks like smoking, alcohol use, obesity, malnutrition, and sexual practices. The Framework Convention on Tobacco Control shows how international policy addresses tobacco and health.

Explore how culture shapes health beliefs, behaviors, literacy, and access to care; examine cases like cannibalism-linked kuru and alcohol norms to tailor global health solutions.

Examine how politics, geography, and displacement interact to influence health outcomes, as population movements drive infectious disease spread and create demand for health services in both origin and host settings.

Examine environmental determinants shaping global health through water, sanitation, and hygiene; climate change, air pollution, deforestation, and vector-borne diseases, with policy implications like the Paris agreement.

Explore how the major determinants framework links cultural, behavioral, socioeconomic, geopolitical, and environmental factors to population health, with examples and policy implications for global health today.

Explore fundamentals of health systems and their funding models tax-based, private, and social insurance, using the WHO building blocks and services package. Examine universal health coverage, its importance and challenges.

Explore how policymakers and researchers analyze health systems using the six building blocks and the essential package model to compare, evaluate, and improve care.

Compare tax-based, private, social insurance, and out-of-pocket health financing models, highlighting equity, universal access, and the trade-offs of cost, taxation, and coverage.

Examines universal health coverage as a system delivering access and financial protection through a defined service package, funded by public and private sources, highlighting primary care and cost coverage.

Gain a solid understanding of approaches to analyze and compare health systems, explore global financial models for health care, and examine universal health coverage and its challenges.

Explore the origins and definitions of global health and measure the global burden of disease for research. Examine HIV/AIDS, TB, malaria, Ebola, pandemics, determinants, health systems, and universal health coverage.
