We stayed at the Barcelo Maya Beach resort from December 28, 2007 until Jan 4, 2008. My fiance started to show signs of illness a couple of days after we returned. He died on Jan 11. Another couple that we met at the resort also where sick when they came home. They where treat for Malaria and are fine now.
If you plan to visit this area be cautious. If you are sick when you get home go to the doctors immediately.
