Take precautions - wash your hands more than you would at home, (especially before eating) and use the sanitizer dispensers provided and you should have no problem. In fact if everyone followed those precautions, there would be a lot less cases reported.
Could not agree more. Whan we cruised Alaska on the MS Statendam we were required to "Purel up" prior to entering the dining room and prior to eating on the Lido buffet. I never used as much Purel during that 7 days than I have during the by prior 60+ years. I got into the habit of taking a shot of Purel whenever I passed a dispensor...hallway, elevator, dining areas etc. It worked as we were as healthy after 7 days as when we started.
