Can you seal up the bag and keep it away from the family till AFTER the holiday? this way no one is exposed? The laundry mat is a great idea as well. Wash on the hottest setting possible, and make sure you add bleach! Bleach will kill antrax as my momma sez.

Keep YOUR hands spectacularly clean and dont touch your face. Make sure all the little ones wash before meals, and use soap AND hot water. kids are kids and they all have their own virus stuff going around, but that nursing home stuff can be quite nasty. I used to have special shoes to wear at work, and left them on the door stop when I worked on the ambulance. I didnt allow them in my house. Drag out the lysol and get spritzing.

I hope mom feels better quick.
