Just pass 'it" to a successful hooker
I know its kinda implied that Paul goes to a hooker (does he ?)
wouldn't that give a you long start line? if you pass it to a hooker, especially a successful one, she would probably infect several people ,before "it " even shows up to her (it might not even show up to her because she's already passed it on)..and if if its a guy who frequents hookers, he may pass it on to more hookers, who pass it to more johns, making a large web of people who would have to be knocked off before it gets back to you
