I'm going to be the first to tell you that I went on a trip to Tenn. feeling fine stayed at a hotel for 3 nights and it was about the 2nd night I was in bed and I started to feel sick. I used their glass to rinse my mouth out from bushing my teeth and i used their glass to take my meds and i to for now on will bring my own disposable glass for such things for now on. you can have 5 health depts down their backs once they leave it goes back to normal routine. the helath depts cant babysit them hotels 24/7 7 days a week, 12 months a year.
