article imageReview of tourists and disease 'hot spots'

The U.S. CDC has analyzed travel-associated illness trends and clusters for the period 2000–2010. The report has highlighted the most common diseases and the regions of the world where infections occur most often.
The Centers for Disease Control (CDC) has conducted a review of U.S. tourists and the types of illnesses that they pick up when traversing the globe.
For the research an international study analyzed data from more than 42,000 returned travelers to the U.S. The tourists visited 18 travel health clinics worldwide between 2000 and 2010. The clinics were part of the GeoSentinel surveillance network.
The analysis revealed that travelers who presented for post-travel care increasingly had visited developing regions. The most common destinations from which ill travelers returned were sub-Saharan Africa, Southeast Asia, South Central Asia and South America, with a substantial increase in proportion detected among those returning from South Central Asia.
The clinics reported significant increases in ill travelers returning with enteric fever (typhoid or paratyphoid) and dengue (a viral infection). At the same time, they observed a significant decrease in malaria, which may in part be due to better tolerated malaria preventative drugs.
It is hoped that these data will help guide physicians and travel health experts caring for travelers presenting with illness. It is also hoped that the information will counsel travelers about steps travelers should take to protect themselves from disease while traveling internationally.
The full report will be published in next month's edition of the journal Emerging Infectious Disease.
