What Are the Key Concepts in Epidemiology of Infectious Diseases?
Several fundamental concepts are essential:
Incidence: The number of new cases of a disease in a specific population and time period. Prevalence: The total number of cases, both new and existing, in a population at a given time. Reproductive Number (R0): The average number of secondary infections produced by an infected individual in a completely susceptible population. Herd Immunity: When a large portion of a community becomes immune to a disease, making the spread of the disease from person to person unlikely.
