I have not seen any mention of the bacterial illness that travelers often get. Is that because it is now so easy to avoid? I heard things like you shouldn't let sink water touch your lips during your shower, nor should you use tap water to brush your teeth let alone drink it. What about eating lettuce in salads, on sandwiches?
Are ice cubes in cocktails a problem? Does alcohol help? How careful do I have to be? I do have a pretty sensitive system and don't want to spend my vacation indoors. Any advise? Are these old wives tales?
