|Description:||This 1993 photograph depicted a view of Istanbul, Turkey, from the Bosphorus, which is the winding strait that separates Europe from Asia. The Bosphorus is its own tourist destination with a mixture of modern hotels, and stone fortresses, as well as fishing villages. Istanbul, as can be seen from the photo, has air pollution problems similar to many of the world’s largest cities, and is increasingly becoming a business destination, as well as a place for tourists. It is important for all travelers to be aware of the potential health hazards of travel to any destination, foreign or domestic.|
Improvements in transportation and communication have linked people around the world as never before. Rising levels of affluence have meant that people from all over the world now travel with greater frequency. To address health issues associated with travel, the Centers for Disease Control and Prevention offers tips for U.S. travelers on how to avoid illness while away from home. A greater problem is that of globalization’s effect on infectious disease transmission. Health problems can no longer be thought of as “local.” CDC’s “PulseNet” is one effort used to monitor laboratory gel patterns to quickly identify dispersed domestic and international outbreaks of infectious disease.
