Epidemiology Foundations: Understanding Public Health and Disease Patterns

In an interconnected world, understanding how diseases spread and how health outcomes are measured is more critical than ever. This course introduces you to the core science of public health, demystifying the patterns, causes, and effects of health conditions in defined populations. You will transition from having a general curiosity about public health to being able to read and interpret epidemiological data, calculate basic disease frequency measures, and understand how modern health policies are formed. What you'll learn: - Understand foundational terminology, including incidence, prevalence, endemic, epidemic, and pandemic. - Calculate key public health metrics such as mortality rates, relative risk, and odds ratios using written step-by-step guides. - Analyze different study designs, from observational cohorts to randomized trials, and recognize their strengths and limitations. - Explore modern digital epidemiology methods and surveillance systems used to track outbreaks in real time. - Evaluate public health interventions and the ethical considerations of data collection and population health tracking. The course begins with essential definitions and historical foundations of public health science, gradually guiding you through study designs, quantitative calculations, and modern digital tracking methodologies. Through structured readings and written practice scenarios, you will build a practical foundation in epidemiological thinking.
