I'm not quite seeing why I should worry about whether the linens on my hotel room bed are laundered during my stay. As long as they were clean when I got there, they will presumably only become an infection vector if I am already ill---and in that case it won't matter. What is crucial, it seems to me, is that the sheets are changed and laundered carefully between guests. Sadly, an Atlanta TV station recently found that major hotel chains were not even doing a proper job of cleaning the cups and glasses in the rooms, let alone changing the sheets:
