Infected: a novel

Yesterday I was in Borders looking at their buy one get one 1/2 off table and found this book: Infected: a novel. It looked kind of interesting so I read the back:

A mysterious disease is turning thousands of ordinary Americans into raving, paranoid, murderers who inflict brutal horros on strangers, their own families, and even themselves. And one morning, ex-football star Perry Dawsey awakens to find mysterious welts growing all over his body. Soon Perry finds himself acting and thinking strangely, hearing voices, fighting uncontrollable rage...he is infected. Worse, the disease wants something from him, something that could alter the fate of the human race.

Sounds like a kind of zombie book to me. So I read a couple chapters and ended up buying it. So far the writing isn't that great, but the premise of the book is really interesting. I'm wondering if it will bring up SIR models, how many individuals need to be vaccinated (if there is a vaccine) to protect the community, and issues about quarantines.
