Question 2 : Consider a disease for which only 25% of individuals who have become exposed are progressing to become infectious. However, whether or not an individual becomes infectious can only be determined after a 5-day latent period. Individuals who are not progressing to become infectious will remain susceptible. The average time an individual stays infective is 2 days. Also, after an average of 10 days after having recovered, 10% of recovered individuals will revert to become susceptible again. 90% of the individuals, however, acquire lifelong immunity. (a) Develop the transition diagram that depicts the move of individuals between compartments. Hint: you can use PowerPoint or online tool such as https://app.diagrams.net/ to draw the diagram. The diagram should contain the labels of the stages and have arrows indicating from one stage to another stage. ******Susceptible, invectives, and recovered individuals in the SIR model are moving through "the compartments " S-I-R. The SIR model is referred to as compartmental model as you move individuals out of one compartment into another. *******
