Disease virulence The Kermack-McKendrick model for infectious disease transmission (see Exercise 7.6 .23 ) can be used to predict the population size $P$ as a function of the disease's virulence (that is, the extent to which the disease kills people). The population size $P$ is large when virulence $v$
is low and it is also large when virulence is high because the disease kills people so fast that very few people get infected. For a specific choice of constants, the population size is
$$P(v)=\frac{10+v+v^{2}}{1+v} \quad 0 \leqslant v \leqslant 9$$
Find the smallest and largest population sizes and the virulence values for which they occur.

Everybody. So today we're gonna be going through problem number five in chapter 15 therapy, and this problem is testing our knowledge of behavior therapy. So I'll first start off by talking a little bit about the main idea behind behavior therapy or the principal. We can say so. Behaviorists believe that every single behavior we can learn all behaviors are learned. I'm gonna write that down here, all behaviors I learned. So they postulate that if all behaviors are just learned responses, we can unlearn unhealthy behaviors, which makes enough sense. So I'm gonna write that down. Unhealthy behaviors can be unlearned, so that's essentially what they try to dio. The overall aim of this specific type of therapy is to stop any unhealthy or unwanted actions by simply unlearning them.

Okay, So if we have a differential equation off D I d t is equal to beta times that I hind end minus I almost minus mu times I where eyes the number of infected people so we can find all the equal of river plugging in points. So beta is equal to 0.1 uh, played by eye and is equal to 1000 minus. I minus muse equal to two eye. So he set this equal to zero. Uh, and then solve this out. End up with this s t zero. So this is becomes 10 I minus 0.1 I squared minus two. Eye is equal to zero. Eight. I, minus 0.1 I squared is equal to zero. We factor out I ate my eye. It's equal to zero. So we know that eyes equal to zero and I is equal to, um eight. Divided by 0.1 is equal to 800. Okay, So to determine whether each of these air stable or unstable, we define a function g off I that is equal to veda I times and minus I minus mu. I sold for G prime off I on then plug in chief crime of zero energy crime off 800 and check with these were greater than or less than zero.

In this problem. They want us to evaluate the limit as he approaches infinity and then interpret our result. Now, if we were to evaluate the limit here, um, applying it directly, we get infinity over affinity, which I don't know that means, but we call it a little trick that they tell us to do is to find the largest power in our denominator and then divide the number and denominator by that. So in the dominated, the large power is B squared. So we'd multiply the top and bottom by b squared. And doing that, we would end up with the limit as he approaches infinity of eight over B all over one, over B squared plus two overby plus one. And now, if we were to go ahead and apply this limit, we know that all of these approach zero and one just a purchase want. So we'd have zero over zero plus zero plus one, which is just 0/1 or zero. So this here would be our limit now to interpret this well, V is our mortality look great? So because the saying is, as the mortality rate increases, then well, this function here was supposed to tell us number of infected. So then the number of infected approaches or gets very close to zero, so number of affected approaches zero, so this year would be our interpretation of the limit.
