Today I asked my teenage daughters to refrain from sharing food & beverages with their buddies for 2 weeks, and to be more careful about washing up and general cleanliness. I reminded them that these policies should be full time but I know they disagree, and that they should humor me and cooperate until Mother's Day as a gift to me. They indicated compliance. The fact that a case in TN was announced on the news this morning reinforced the compliance.
That's all the preventative action I plan to take. We already have food, beverages, medicines, and chicken feed stocked up. That's the norm for us.
