Our family took the Western cruise in August and visited the Tulum Ruins as our Cozumel excursion. We loved it and I've previously posted on that. A couple of weeks ago, my daughter and I went to give blood at the Red Cross. The nurse was going down the long list of screening questions which are designed for the answer to be "no" to be eligible to give blood. When she got to the one about "Have you traveled outside the US or Canada in the past year" I almost said no, but then thought about the cruise and said "We went on a Carribean cruise this summer". She got very interested and asked where we went, exactly. Then she grabbed a big notebook and flipped open a page. There it was on a list of "Unacceptable risk of Malaria": Tulum Ruins. So, my daughter and I were both deferred for 1 year from the trip. We, of course, went home and looked up the symptoms of Malaria (mental confusion is one and my daughter thought perhaps I had it, but did not have the fevers, etc.). Just thought I'd let folks know in case others out there routinely give blood. I'm so used to answering "no", "no", "no" that I almost didn't respond correctly.
