You can do a search for Parvo threads. There are quite a few recent ones here. I copied this one for you. 9 Week old Puppy W/ Parvo Day by day
I have no personal experience with parvo. Yes, it does live a very long time and bleaching is important.
BTW, watch your language. It isn't allowed, not even the letters, or substitute words. It doesn't bother me, but I don't want you to get into trouble. Good luck. I hope your pup stays well.
