Not sure how this is applicable. Really good book, but the super flu in the book had a fatality rate of 99.4%, and wiped out the entire world's population in like 2 or 3 weeks.
Wildly overrated, IMO terrible book. I know this will enrage the King fanbois. It's more than 800 pages of occasionally interesting vignettes mired in tedious narrative, and after all that investment in slogging through it, King basically gives up and delivers the worst sort of deus ex machina ending (nukes magically apprear and...something...the check cashed...and we're done here...).
