Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems. There are three main types of epidemiology: descriptive, analytic, and experimental.
- Descriptive Epidemiology: This type of epidemiology is used to describe the frequency, distribution, and patterns of a health-related event or condition in a population. Descriptive epidemiology can be used to identify risk factors for a disease, identify trends in the incidence of a disease, and understand the natural history of a disease. This type of epidemiology is often used to generate hypotheses about the causes of a disease, which can then be tested using analytic or experimental epidemiology.
- Analytic Epidemiology: This type of epidemiology is used to examine the relationship between a specific exposure or risk factor and the occurrence of a health-related event or condition. Analytic epidemiology can be used to determine the strength and direction of the relationship between an exposure and a disease, and to identify the specific factors that contribute to the development of a disease. This type of epidemiology is often used to test hypotheses generated by descriptive epidemiology and to identify risk factors for a disease.
- Experimental Epidemiology: This type of epidemiology is used to test the effectiveness of interventions or treatments for a health-related event or condition. Experimental epidemiology can be used to determine the causal relationship between an exposure or risk factor and a disease, and to evaluate the effectiveness of interventions or treatments. This type of epidemiology is often used in randomized controlled trials (RCTs) to determine the effectiveness of a new treatment or intervention.
Each type of epidemiology has its own strengths and limitations, and the choice of which type of epidemiology to use will depend on the specific research question and the available resources. Descriptive epidemiology is often the starting point for a research study, providing important information about the distribution and patterns of a disease in a population. Analytic epidemiology can then be used to identify risk factors for a disease and to test hypotheses about the causes of a disease. Experimental epidemiology is used to test the effectiveness of interventions or treatments for a disease.
It is worth noting that the distinction between these three types of epidemiology is not always clear-cut and some studies may have elements of more than one type. For example, a study may use descriptive epidemiology to identify a problem, analytic epidemiology to identify risk factors, and experimental epidemiology to test interventions. Additionally, as the field of epidemiology continues to evolve, new methodologies and techniques are being developed to further enhance the understanding of health and disease in populations.

Loan Amounts and Repayment
The loan amount you can receive depends on your chosen lender and financial need:
- NSFAS: Covers full tuition, residence, books, and a personal allowance. The loan becomes a bursary if you pass all your courses.
- Banks: Can provide up to R120,000 or more annually, depending on tuition costs and credit history.
Repayment usually starts after graduation or once you start earning an income. Bank loans may require interest-only payments during your studies. NSFAS repayment only begins when you earn above a specific income threshold.
FAQs on Student Loans in South Africa
1. Can I apply for a student loan without a parent or guardian?
For government loans like NSFAS, yes. But most banks require a financially responsible co-signer, especially for students without an income.
2. Is NSFAS a loan or a bursary?
NSFAS starts as a loan, but it converts to a bursary if you meet academic performance requirements. This means you may not have to pay it back.
3. What is the interest rate on student loans?
Private banks offer competitive rates between 5% and 12%, depending on the applicant's credit profile. NSFAS charges a much lower interest rate, usually linked to inflation.
4. What happens if I fail my courses?
If you’re funded by NSFAS and fail, your loan won’t convert into a bursary, and you’ll need to repay the full amount. Banks may continue charging interest, and your co-signer may be held liable.
5. Can I use a student loan to pay for accommodation and laptops?
Yes. Both NSFAS and many bank student loans cover costs beyond tuition, including housing, meals, textbooks, and electronic devices like laptops or tablets.
