Question

Quizplus · Accepted Answer

The S-I-R model characterizes the transmission dynamics of infectious diseases by dividing the population into susceptible (S), infected (I), and recovered (R) individuals. It tracks how individuals move between these categories and models how the disease spreads through the population. Therefore, the S-I-R model specifically represents transmission dynamics and not immunity rates, treatments, or fatality rates.
