Discinfect your entire house, wash all bedding and clothes in hot water, and there is a soap you can get over the counter that the entire family will need to bathe with for 3 days straight (feet to neck, no head or face). It is the same soap that surgeons scrub with before surgery. I apologize that I can't remember the name of it. Keep the sore covered until it is totally healed.
I strugged with this earlier this year. It took us a long time to get everyone cleared up for good. If you want you can email me and I will share more info with you or find the name of the soap (I think I still have some left).
