FROM MARTY'S EARLIER POST, THERE HAVE BEEN NO OUTBREAKS OF ANYTHING REPORTED!
If you have plans to go down and are concerned, get the vaccines that your travel doctor recommends, use bug spray, wash your hands and follow the normal travel rules regarding what you eat. Also, check with CDC on the internet: http://www.cdc.gov/travel/camerica.htm
Let's stop the rumours before they begin unless they have been substantiated by reliable sources. Thanks!
