In fact, nearly three quarters of Americans drink coffee every day and an astounding 2.25 BILLION cups are consumed each day. So we aren't exaggerating when we say that Americans love their coffee.
For the full specification of the model, the arrows should be labeled with the transition rates between compartments. Between S and I, the transition rate is assumed to be (/) / = /, where is the total population, is the average number of contacts per person per time, multiplied by the probability of disease transmission in a contact between a susceptible and an infectious subject, and / is ...
