Introduction to Epidemiology and Measures of Disease

This foundational topic introduces Zambian tertiary students to the core concepts and tools of epidemiology, the basic science of public health. It defines epidemiology as the study of the distribution and determinants of disease frequency in human populations, with the ultimate goal of prevention. Students learn to categorize disease patterns by person, place, and time, and understand key terms like endemic, epidemic, and pandemic. The topic provides a thorough grounding in the calculation and interpretation of essential measures of disease frequency, including prevalence (point and period), incidence (cumulative incidence and incidence rate), and attack rates. For students pursuing diplomas or degrees in biomedical sciences, public health, or medicine in Zambia, this knowledge is directly applicable to monitoring and understanding the burden of both infectious (e.g., malaria, HIV/AIDS) and non-communicable diseases within the country. It forms the basis for conducting disease surveillance, evaluating public health interventions, and contributing to evidence-based health policy and planning in the Zambian context.
