Since I last posted here... I'm infecting folks in all the worlds by giving them the fruit while out in active careers and also out visiting and planting the fruit in gardens and community lots on my infected sims. It doesn't just spread on it's own and the infection won't spread on it's own... You the player have to make that happen. If you don't want it in other worlds it won't happen unless you put it there.
The infected become possessed for some hours during the night.. and eating fruit will bring on a possession state. I did read from another player that a vampire can become infected by drinking of an infected sim. I haven't tried that.. but is pretty funny to me.
