Have you ever wanted to travel to an exotic, tropical locale, while taking part in an important study that could end a scourge that has plagued travelers for centuries? If you answered yes to that run-on question, then we have a travel tip for you. is currently seeking travelers to take part in a clinical research study to test an experimental new patch designed to prevent Travelers' Diarrhea. In fact, they're even willing to pay for all travel expenses for the men and women who join the study, provided they are willing to go to one of nine different destinations in Mexico or Guatemala and stay for at least seven days. The destination cities in Mexico include Guadalajara, Oaxaca, San Miguel de Allende, and Mexico City. Those interested in visiting Guatemala instead, are asked to visit Antigua, Quetzaltenango, Panajachel, or Guatemala City instead.

Eligible travelers must be between the ages of 18-64, in good overall health, and be willing to maintain a diary of their usage of the new patch for up to 17 days. To remain eligible, you must also meet some other criteria, such as not having received a diarrhea or cholera vaccine before you travel. To view the complete list of requirements, click here. You can also find answers to many other questions on the research studies' FAQ which is found here.

Unfortunately, this study, and therefore the travel deal, are not open to just everyone. There are also a list of departure cities with clinics which will be conducting the research, and all participants will have to travel through those cities. That list includes Belfast, Glasgow, London, Manchester, Birmingham, and Reading in the U.K., and Berlin, Munich, Hamburg, and Potsdam in Germany.

Interested travelers who meet the requirements and would like to join the study are encouraged to apply online.
