Summary
Epidemiology is the study of how diseases spread. This guide helps students understand key terms and interpret data about disease outbreaks.
Key Terms in Epidemiology
Epidemiology studies diseases. It explains terms like communicable, noncommunicable, bacteria, virus, outbreak, epidemic, pandemic, surveillance survey, risk, vector, fomite, zoonosis, transmission, incidence rate, mortality rate, prevalence, agent and host.
Triads for Disease Outbreak Analysis
Scientists use triads to analyse disease outbreaks. The triads are time/place/person and agent/host/environment. Each triad helps understand the outbreak situation.
Disease-Causing Agents and Transmission
Disease-causing agents have different categories. Each category has different modes of transmission. Students learn how to prevent the spread of disease.
Data Interpretation and Calculations
Students learn to interpret data from tables, charts, maps and graphs. They calculate relative risk, attack rates and odds ratios. They use data to understand disease situations.
Key terms
- Communicable (Infectious)
- Diseases that spread from one person to another.
- Noncommunicable (Noninfectious)
- Diseases that do not spread from one person to another.
- Epidemiology
- The study of how diseases spread in populations.
- Outbreak
- A sudden increase in cases of a disease.
- Incidence rate
- The number of new cases of a disease in a population over time.
- Prevalence
- The total number of cases of a disease in a population at a given time.
