Students begin by developing an understanding of the evolution of epidemiology and how the discipline is applied today. This provides important context for understanding how epidemiologists investigate patterns of disease, identify risk factors and contribute to public-health decision-making. For Caribbean professionals, this foundation can help connect historical approaches to modern challenges involving infectious diseases, chronic diseases and population health.

This area introduces fundamental measures used to understand disease within populations. Students examine concepts such as prevalence and incidence, which are essential for determining how widespread a condition is and how frequently new cases occur. These measures are particularly useful for interpreting health statistics and evaluating the burden of disease within Caribbean communities.

Students develop an understanding of how statistical information can be organised, summarised and interpreted. Descriptive statistics provide the foundation for communicating health trends and identifying meaningful patterns in population data. These skills can be valuable for professionals involved in health reporting, programme monitoring and community-health planning.

This study area introduces methods used to draw conclusions from research data. Students explore concepts including confidence intervals, p-values and hypothesis testing, helping them understand how researchers determine whether observed findings are likely to represent meaningful relationships rather than random variation.

Students explore important analytical tools used to examine relationships between exposure and health outcomes. Odds ratios and relative risk are widely used in epidemiological research to assess associations, while simple regression provides an introduction to analysing relationships between variables. These skills can strengthen a student's ability to interpret published health research and evidence.

Effective epidemiological research depends on obtaining appropriate samples and determining whether a study has enough participants to produce useful findings. Students examine sampling principles and sample-size calculation, developing an appreciation of how research studies can be designed to generate reliable and meaningful results.

Students investigate observational research approaches and the importance of standardisation when comparing health outcomes across different populations. This is especially relevant when examining disease patterns across communities, age groups or geographic areas and can support more accurate interpretation of Caribbean health data.

Ethical practice is fundamental to health research. Students consider ethical issues associated with epidemiological research while examining the types and sources of data available to researchers. This helps future health professionals appreciate the importance of responsible data use, confidentiality, research integrity and protecting individuals and communities.

This area introduces students to studies designed to evaluate interventions and to methods for reviewing research evidence. Understanding how interventions are assessed can help professionals determine whether particular public-health strategies are supported by evidence and whether they are appropriate for specific populations.

Students develop the ability to critically assess research rather than simply accept published findings at face value. Critical appraisal is an important professional skill because healthcare and public-health decisions increasingly depend on the quality and reliability of available evidence.

Global surveillance examines how health information can be monitored to identify emerging patterns and threats. This is particularly relevant to the Caribbean, where effective surveillance can support early identification of infectious-disease outbreaks and other public-health risks. The knowledge gained can be valuable for professionals working across national, regional and international health systems.

The course also considers the relationship between epidemiology and social media, reflecting the growing role of digital communication in public health. Students can develop a better understanding of how health information, public perceptions and disease-related communication interact in the digital environment—an increasingly important consideration for health agencies and professionals.
