PUBH6005 Epidemiology course will test student's skills in epidemiology and learn key concepts about Epidemiology. It will cover topics such as different epidemiological methods, statistical analysis, ways to determine a correlation between diseases, and the use of different critical appraisal checklists. It is the study and evaluation of the distribution of diseases and disease patterns in a given population.
Epidemiology is one of the important elements of human health and epidemiological investigation helps to determine the risk factors of diseases and preventive care needs. Epidemiologist plays a role in designing such investigations, collecting data, conducting statistical analysis, and interpreting changes. Eventually, one such study is accepted, they also take part in the dissemination of findings. Epidemiology is a subject that ensures the development of methods to promote clinical research, public research, and other primary research in biological science.
Unit details of this course include the following:
Unit code: PUBH6005
Location: Torrens University Australia
Study level: Graduate students
Brief on PUBH6005 Epidemiology
The course is designed for bachelor's students and it will test their knowledge in grasping the subject. Some of the important topics of epidemiology are estimating disease prevalence rates, approach and methodologies, calculation methods, and different areas of epidemiology such as environmental and clinical epidemiology.
The assessment will consist of two parts. The first assessment will be related to online quiz with 70 multiple-choice questions. It will test students’ ability to understand the epidemiological context and understand the decision-making process to be implemented for specific disease-related scenarios. The quiz will have direct questions related to theories. In addition, it will also have a certain tricky question that will ask students to calculate the prevalence rate or risk ratio of any disease. It will test the critical thinking skills of students by asking them to interpret the actions to be taken in a specific scenario.
The minimum qualification score for the quiz will be 50% and anyone below the score cannot move to the next semester. The second part of the assessment will be a critical appraisal activity. Each group of students will be given different epidemiological articles and they will be asked to critically appraise the articles using a specific checklist. The qualifying marks for the critical appraisal task will be 40% and it will evaluate how far students can develop their critical appraisal skills.

Each module gives students a basic understanding of the subject. In relation to PUBH6005 assessment answers, it can be defined as a study that investigates the prevalence and risk factors of the disease and evaluates the future course of action to minimize the burden. The purpose of epidemiological studies is to identify the strategies to prevent any disease. It is useful in guiding policy-related changes. All the findings in epidemiology are related to a definite population group. One of the key features of epidemiology is that it can effectively identify the population at risk, healthy or sick people, and those who cannot engage in any further calculations.
The different epidemiological model also exists to test the occurrence of diseases. One model is linked to susceptibility and exposure factors. It is based on the assumption that the development of any disease depends on susceptibility to any disease and exposure to the illness. For example, a person must be exposed to a person who is infected with measles disease before the disease is transmitted to that individual. The second immunological model is the epidemiological triad, which regards that the occurrence of any disease depends on the balance of host, agent, and environmental factors.
The course introduces students to many new terms and concepts related to epidemiology. It includes terms like crude, specific and adjusted rates; relative risk, risk ratio, morbidity, and mortality rates. The crude rate is the total number of disease cases and the entire population in the calculation. The specific rate is the differences in cases by age, race, and other factors. The advantage of an adjusted ratio is that it allows for the comparison of people belonging to different groups. The morbidity rate is the presence of illness or symptoms related to a disease, whereas mortality refers to the rate of death caused by any disease. These terms can give an insight into the burden of acute and chronic diseases.
Incidence and prevalence rate is a widely used term in epidemiology. The incidence rate is defined as the measure of the occurrence of any new disease in a population. The prevalence rate is termed as the total number of existing cases or new diseases in a population group. Epidemiology is a subject that has great implications in the field of public health. It supports the disease surveillance process and helps to identify hazards. The other uses of epidemiology are as follows:
To conduct an investigation on the history of any disease and propose useful projections about the future
To diagnose the health of any community by measuring the distribution of illness using variables such as the incidence rate, prevalence rate, disability, and mortality rate.
To study the performance of health services and identify areas of improvement
To survey a population group regarding their risk of disease and accident
To identify any syndromes by evaluating the distribution of any clinical phenomena
To understand the complete picture of any chronic disease by looking at their natural history
To assess the causes of health and disease by calculating the relative risks.
