Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare ...
Epidemiology plays an essential role to ensure the public's health through research and practice. Without research—at Johns Hopkins and at thousands of other universities, medical schools, and research institutions across the nation—scientific breakthroughs suffer, and the lifesaving treatments of tomorrow are at risk.
This course provides an overview of epidemiology, including key terms, sources of data, and study design. Learners will calculate different rates of disease and go through the steps an epidemiologist takes to investigate a disease outbreak.
Epidemiology is the branch of medical science that investigates all the factors that determine the presence or absence of diseases and disorders. Epidemiological research helps us to understand how many people have a disease or disorder, if those numbers are changing, and how the disorder affects our society and our economy.
Epidemiology publishes original research from all fields of epidemiology. The journal also welcomes review articles and meta-analyses, novel hypotheses, descriptions and applications of new methods, and discussions of research theory or public health policy. We give special consideration to papers from developing countries.
Epidemiology, branch of medical science that studies the distribution of disease in human populations and the factors determining that distribution, chiefly by the use of statistics. Unlike other medical disciplines, epidemiology concerns itself with groups of people rather than individual patients
