One of the most often used statistics regarding a disease is its basic reproductive rate. This is unfortunately denoted as Ro, even though it has little to do with the recovery curve R(t). So what is Ro? It measures how many people an infected person will spread the disease to over the course of their illness. Recall that if a person is infected for W weeks, then the recovery rate is b = 1 Thus, the length of the W influenza is W = 1 weeks. Also remember that a was the rate an infected person spread the virus to others each week. So if we spread to a people each week, and the disease lasts 1 weeks, then we can expect each person to spread 1 others over the course of their illness.
