In epidemiology, increased risk of infection is often measured using various epidemiological metrics such as incidence rate, prevalence rate, and relative risk.
Incidence rate: The number of new cases of infection in a specific population during a defined period. Prevalence rate: The total number of cases of infection, both new and existing, in a population at a specific point in time. Relative risk: The ratio of the probability of the event occurring in an exposed group to the probability of the event occurring in a non-exposed group.
